Challenger Shuttle disaster: Recovery of data from damaged tapes


On January 28, 1986 the Challenger rocket disintegrated shortly after takeoff spreading debris over about 500 square miles.


As an introduction to this event Francine Bellson will cover how Silicon Valley’s engineering & education communities coalesced to return a personal token from the Challenger flight that local students had given to Astronaut Ronald McNair


About seven weeks after the disintegration tapes containing flight and crew data were recovered after having been immersed in 100 feet of salt water. They were so corroded that they resembled a brie doughnut and the data were deemed unrecoverable by NASA and the tape and the drive manufacturers.  A chance meeting of NASA officials with IBM scientists and engineers at IBM’s Tucson laboratory led to the recovery of the data.


Dr. Ric Bradshaw led the team that recovered the data. His observations, findings and conclusions are memorialized in a set of images that he will discuss at this meeting.  Ric has more than 40 years experience in tape media development and can share his opinions and observations on the state of the industry during the question and answer period.




Dr. Bradshaw received a B.S, in Chemistry from New Mexico Institute of Mining and Technology and a PhD in Synthetic Organic/Polymer Chemistry from Arizona State University.  He joined the IBM Tucson laboratory in 1978 and was instrumental in the development of tape formulations starting with the 3480 and continuing thru to today’s LTO.  He was a member of the IBM Academy of Technology and has represented IBM at numerous storage industry and technology organizations.  He retired from IBM in 2007 and is now consulting to the storage industry.


Francine Bellson came from MIT (SM, Physics) to Silicon Valley in 1974, where she’s worked at Fairchild R&D, Varian Assocs. and IBM. Mrs. Bellson is an active member of this committee, a senior member of SWE, a Life member of IEEE and a member of IEEE-WIE.

Gravitational Waves and
The Laser Interferometer Gravitational-wave Observatory (LIGO):
A Technical History

This session will comprise a talk by Stan Whitcomb followed by a panel discussion.

Talk Abstract:

The first detection of gravitational waves by the LIGO is remarkable not only because of its impact on the Theory of General Relativity and on the astrophysics of neutron stars and black holes, but also because of the sensitivity of the detectors required. The LIGO interferometers had to be capable of discerning changes as small as 1E-18 m in the length of its 4-km long arms, certainly one of the most precise physical measurements ever made.

The LIGO Lab is operated by Caltech and MIT through funding from the National Science Foundation. It comprises observatories in Livingston, Louisiana and Hanford, Washington, in addition to the groups at Caltech and MIT. The broader LIGO Scientific Collaboration currently includes approximately 1000 scientists, engineers and students from more than 60 institutions in 12 countries. After thirty-five years of development and construction,

The first gravity waves detected by LIGO were created by the collision of two black holes was made simultaneously in Louisiana and Washington State on September 14, 2015 and announced on February 11, 2016. The detection of gravity waves confirmed the predictions of Einstein’s General Theory of Relativity and ushered in a new era of gravitational wave astronomy.

With its partner the Virgo Project, LIGO will form the core of an international network of gravitational wave detectors, seeking to learn about the universe through a new type of signal. To achieve this incredible sensitivity, LIGO scientists spent over 30 years understanding and overcoming a plethora of competing noise sources.

In this talk, Stan Whitcomb will describe a diverse handful of these noise sources, selected because of their importance to the project or their broader general interest, and trace the sometimes circuitous path that led to each one being brought under control

  • Stan Whitcomb PhD, Former Chief Scientist of the Laser Interferometer Gravitational-wave Observatory
    Stan received his BS degree in 1973 from Caltech and then a PhD at the University of Chicago in far-infrared and submillimeter astronomy in 1980. He returned to Caltech in 1980 as an assistant professor of physics, near the beginning of Caltech’s entry into the field of gravitational wave detection. He has been involved in nearly every phase of the effort to build LIGO—concept development, prototype sensitivity demonstration, detector design and installation, commissioning, data analysis, and management. He is a Fellow of the American Physical Society and of the Optical Society. He was awarded the Henry Draper Medal (National Academy of Sciences) in 2017, and the C.E.K. Mees Medal (OSA) in 2018.
  • Brian Lantz PhD, Senior Research Scientist, LIGO Group, Stanford University
    LinkedIn Biography
  • David Adler PhD, President and CEO of Silicon Valley X-Ray (SVXR)
    In 1981 Dave a sophomore at Caltech was offered a summer job by his physics teaching assistant, Yekta Gursel, to “build a gravity wave detector” on campus. That summer they bolted together the 40-meter predecessor to LIGO. For his senior thesis, Dave worked with Stan Whitcomb to develop a laser stabilizer for the gravity wave detector.  Since then, Dave has developed novel optical systems using ions, electrons and x-rays. He has about 100 patents covering ion, x-ray and electron optics and semiconductor inspection. He started SVXR in 2012 to develop 100x faster x-ray inspection systems.

A presentation on the history of the hard disk drive[i] at the August 2017 Flash Memory Summit identified “key figures” in the hard disk drive industry and their “breakthroughs” – the key figures were mainly PhD’s from IBM which is not surprising given IBM’s dominance of the industry into the 1990s and the fact that the presenter was also a PhD who spent most of his career at IBM.  It wasn’t my list but it is certainly true that everyone identified made significant contributions in HDD technology, products and/or markets.

However, there were a number of incomplete facts or actual errors that need correction, including but not limited to:

  1. RAMAC 350 disk storage – The first production unit shipped in November 1957 (not 1956), it weighed less than 1 ton (not more than) and had a purchase price of $34,500 (not about $50,000) for a capacity of 5 million 6-bit characters (3.75 megabytes not 5 megabytes).
  2. Al Hoagland – Hoagland’s many accomplishments do not include responsibility for either the RAMAC head or the 1301 Disc Storage. There is no question that he was involved in both programs but according to the historical record Edward Quade[ii] was responsible for the RAMAC transducer and Al Shugart was responsible for the 1301[iii]. The RAMAC magnetic transducer was initially developed in 1953[iv] within IBM SJ’s Physics department then led by Quade.  Hoagland a professor at Berkeley did consult with Quade in the summer of 1954[v]; he became full time IBM employee in mid-1956.[vi]
  3. Al Shugart & Finis Conner – Both are well known storage executives. Shugart was not in the storage industry[vii] when it was recognized that “a hard disk drive could replace a floppy drive as a valuable, high capacity product for the emerging desktop computers.”  The first such drive, the SA1000[viii] was publically announced before Shugart reentered the industry with the founding of Seagate Technology in late 1979.    Finis Conner from his experience as a sales executive at Shugart Associates was well aware of the success of the SA1000 when he approached Shugart to found Seagate.
  4. John Squires – The actual founding of Conner Peripherals is different than presented.  Squires with the help of Terry Johnson[ix] in June 1985 formed CoData in Colorado[x] and developed the first low cost 3½-inch 40 Mbyte drive.[xi]  Advised to seek stronger marketing management, Johnson and Squires recruited the then unemployed Finis Conner[xii] which ultimately resulted in the 1986 merger of CoData into Conner’s shell corporation, Conner Peripherals, with Conner as CEO.
  5. David A. Thompson – Thompson is cited for his work in development of the thin film head which although important to IBM was less significant in an industry that continued to improve ferrite heads. Since ultimately, the thin film structure did become the writing element for magnetoresistive heads the omission of the MR head from the presentation[xiii] and Thompson’s indisputably significant work on the MR head[xiv]  was somewhat surprising.
  6. Zoned Bit Recording (ZBR) – The first ZBR products were introduced into the market in the 1960s[xv] long before 1987, the earliest filing date of the three patents cited. Apple introduced a variant on ZBR with its 400K Macintosh Floppy Disk Drive in 1984.
  7. PRML (Francois Dolivo) – The first PRML product introduced to the storage market was not the IBM disk drive in 1990 based upon Dolivo’s work, but rather the Ampex DCRS (digital cartridge recording system) in 1984 based on the work of Coleman et. al.[xvi]

Time was limited so the presenter was limited in the number of key figures he could identify.  I do think there were three key figures that should have been included:

  1. Jack Harker – Harker was actually mentioned in passing but IMO his continuing accomplishments from RAMAC to the 3380 merit individual recognition. Among them was the reduction to practice of the first air bearing head[xvii] for disk storage which was then used in the 1301 and all subsequent disk drives, albeit with further improvements.
  2. Mike Warner – Warner holds the patent[xviii] on the Winchester head, a breakthrough to a low mass, low load, close flying and low cost head which in the opinion of Al Shugart was “one of the four most significant events in the history of mass storage.[xix]” Arguably this concept remains true to date albeit with further improvements.
  3. Tu Chen – As an individual contributor and as a founder of Komag Dr. Chen was instrumental in the commercialization of sputtered media.

On the whole it was interesting to hear one person’s view of the hard disk drive industry’s history.  Of course, mine is somewhat different.

Dialog: The Beginning of Online Search


A panel of former Dialog employees and a Dialog user will discuss growth of Dialog starting with its conception within Lockheed.

Dialog is a computer service that allows users to interactively search databases using keywords. When it was first used by NASA in 1967 and then commercially available in 1972, remote access was by way of a modem and telephone line. Dialog’s unique capabilities allow scientists, engineers and others to stay current with work in their fields. Created within Lockheed Corp., the system has been particularly popular for pharmaceutical, engineering, scientific, medical, educational and intellectual property research.

Prior to the availability of Dialog, research of existing work was performed primarily using printed published literature, microfilm and periodically-published indexes. The system has been in continual use for 50 years, including the 27 years that preceded the emergence of Internet search engines such as Lycos, Infoseek, AltaVista, Yahoo! and Google. Dialog broke ground for online search and provided a sound foundation for all that followed.

The panel will discuss insights that led to its development, how it grew as an intrepreneurial project within Lockheed, the transition to a services business as the Dialog Information Services company, strategies that led to its growth and dominance within the industry, and how Dialog was an important government, educational and corporate tool.  Also discussed will be its sale to Knight-Ridder in 1988.


Roger Summit, PhD, is the founder and Chairman Emeritus of Dialog.  He conducted pioneering work starting in 1964 that led to the creation of Dialog, and held executive positions there until his retirement in 1992.  He has served on national and international advisory boards, in professional associations, has received numerous honors, and has published over 100 papers and journal articles based on his knowledge of and experience with online information services.

Elizabeth Trudell, MLS, joined Dialog in 1983 and has been as a long-time member of the executive team, serving as VP of Global Marketing and VP of Product Management.  She has extensive experience in marketing, product management and strategic planning in the information industry, and she led the development and launch of the first web interface for Dialog.  Since 2014, she has been an Associate in the Information and Knowledge Strategy (IKNS) program at the Columbia University School of Professional Studies.  She also serves on the Advisory Board of the Center for Information Research and Innovation (CIRI) at San Jose State University’s I-School, and is Vice Chair of the Board of the non-profit organization Subud California.

Robert Simons, JD, joined Dialog in 1981, and served as General Counsel for 17 years.  Because of Dialog’s unique data access requirements, his activities ranged from developing database license agreements to serving as Dialog’s liaison to the Information Industry Association.  Simons also testified before government committees and panels in the US, Europe and Asia about the value of information to the emerging institutions that were able to benefit from online research. He currently provides legal guidance and advice to the pathology imaging products team of Leica Biosystems, a division of the Leica’s microscope company.

Peter Rusch’s PhD in Chemistry and his interest in computers and chemical information led to his joining the Chemical Abstracts Service’s research department at the American Chemical Society.  In that position he helped customers understand the increasing offerings of chemical information that were then distributed on magnetic tape media.  That work evolved to his being technical liaison to the developing online services.  After joining Dialog in 1975, he developed its chemical and patent information services.

Deborah Hunt, MLS, ECMp, has pursued parallel librarian careers in digital asset management and knowledge management.  She first used Dialog in 1984 to research scholarly works while assisting doctoral students in their areas of specialty which made her quickly appreciate Dialog’s power. She went on to found the first online user’s group in Nevada.  Her work with Dialog let her to write The Librarian’s Skillbook: 51 Essential Career Skills for Information Professionals.  Hunt is currently Library Director at the San Francisco-based Mechanics’ Institute Library, a consultant at Information Edge and a co-teacher of Special Libraries Association (SLA)’s Knowledge Management/Knowledge Services Certificate courses.

The Other Women of ENIAC: Rethinking IT Innovation
An evening with Thomas Haigh – author of “ENIAC in Action”

Co-sponsored with SCV Women In Engineering Chapter


What makes a computing historian tick?  What motivates their research into arcane topics and to lead a group of information technology historians (SIGCIS)?  We’ll learn that and more in an enlightening conversation with Thomas Haigh which will precede his presentation on the very popular book ENIAC in Actionpublished in 2016 by MIT Press.

Haigh explains that the six women now celebrated as the “first computer programmers” were actually hired as computer operators and worked hands-on with the machine around the clock. Other women, who actually built ENIAC, the first general purpose electronic computer, have been forgotten entirely. So has most of the work that made the project so successful, from procuring the right kind of wire to saving ENIAC from flood water.

Popular stories about the history of information technology have usually focused on great inventors and technical breakthroughs, from Charles Babbage and Alan Turing to Steve Jobs and the World Wide Web. Operations work and the labor of non-geniuses has been mostly written out of the history of innovation, but without it no computer would be useful. Information historian Thomas Haigh has written it back in!

Read more about Eniac In Action

The conversation will be moderated by Alan J Weissberger, past chair and founder of the IEEE SV Tech History committee.


Thomas Haigh, PhD is an Associate Professor at the University of Wisconsin-Milwaukee and Comenius Visiting Professor of the History of Computing at Siegen University. He has published on many aspects of the history of computing including the evolution of data base management systems, word processing, the software package, corporate computer departments, Internet software, computing in science fiction, the “software crisis” of the 1960s, IBM in Europe, and the Colossus code breaking machines.

Besides being the author of ENIAC in Action (MIT, 2016) Haigh is the editor of Histories of Computing (Harvard, 2011), a collection of the work of Michael Mahoney, and the lead editor of a 2015 special issue of Information and Culture on the theme “Histories of the Internet.” From 2005 to 2015 he was chair of SIGCIS, the group for historians of information technology.

Fifty years ago, November 7 thru 10, 1966, at the JCC in San Francisco, HP introduced its first computer, the 2116A, although David Packard preferred to call it an instrumentation controller deferring the term “computer” to IBM.  Management was initially adverse to the computer business going so far as to cancel a time-sharing sale to Holiday Inn.

The design team was lead by Kay Magleby who building to HP’s standards produced a very reliable product.  It was the second computer designed in Silicon Valley.

The product was not immediately successful at least in part due to challenges in getting an instrument oriented salesforce to sell computers; in its first year at most five units were sold out outside HP.   Sales took off following marketing and sales changes under the leadership of Tom Perkins

By 1976 revenue from HPs computer products was $340 million, matching all historic instrument’s revenue.  HP was a computer company.

In November 2015 HPs computer business emerged as a $55 billion/year independent company, HP Enterprise.

HP Enterprise declined our committee’s offer to mark this its 50th anniversary.

In the 1970s, Silicon Valley was a very different place.  There were few consumer companies.  Companies were started by PhDs and seasoned business people.  The value of a company was measured in the depth of its patent portfolio or its profits.  Venture money went to companies that solved difficult technology problems.

HP gave us the story of how a couple of young engineers started in a garage and built a major company over a 25-year period. Atari modified that story: a couple of young engineers started in a garage and built a major consumer company in less than 10 years, while having a blast doing it.  The Atari story was the basis for Apple and many of the major valley companies that followed.

Atari, founded in 1972 by Nolan Bushnell, Ted Dabney and Al Alcorn, created the earliest successful arcade and home video games, as well as early personal computers.  This event will include stories about products such as Pong and the Atari 2600, as well as the fun and turmoil surrounding this corner of Silicon Valley from 1972 to 1984.


Nolan Bushnell, the legendary Silicon Valley entrepreneur who co-founded Atari in 1972, was a founding father of the video game industry, and was named by Newsweek as one of “50 Men Who Changed America.”

Al Alcorn: Atari employee #3 who designed Pong (the first commercially successful coin-operated video game), built the first video game on a custom chip (home Pong), and led the development of the Atari VCS home video game machine which launched the cartridge video game industry.

Owen Rubin: early coin-op engineer who helped in the transition from all-TTL games to microprocessor-based games.

Steven Mayer: chief Atari architect for home video games and computer systems, and who was on the team that brought Activision back from bankruptcy to become the world’s largest independent game’s software company.

Brian Berg, IEEE Silicon Valley History Committee Chair, will moderate this panel.

The SF Bay Area has been a hotbed to technology development since the beginning of the 20th century. In this interview panel meeting, you’ll hear how Sigurd and Russell Varian came up with the plans for the klystron at Stanford in the late ’30’s, with critical theoretical contributions from Bill Hansen, physics professor. With a focus on Hansen, we’ll see how the theory and practice of microwave tubes developed locally during and after WW II, resulting in small linear accelerators, and eventually into the 2-mile-long Stanford Linear Accelerator, out behind the campus. The klystron and linear accelerator technology is still in use today around the world, as the prime radiation treatment for cancer.

Dave Leeson is in the final stages of a two-volume book on the life and career of Bill Hansen; he’ll give us ‘inside information’ about those early days, and how this breakthrough happened. Richard Winkler built the first 1-MW klystrons for his Stanford degree thesis, and will discuss their construction in the mid-50’s.  Allen Odian describes how the Stanford Linear Accelerator Center (SLAC) got started, some stories about Panofsky, and “first-beam”.  Burton Richter will tell of the early days of SLAC, and stories of how it was constructed and used. he’ll conclude with some of the physics experiments leading up to his Nobel Prize in 1976.

SLAC was the first of the many IEEE milestones dedicated in the SF Bay area

Join us for an interview of Profs. David Leeson and Burton Richter, as Paul Wesling, IEEE Life Fellow, explores this Silicon Valley technology


Prof. David Leeson, consulting professor of Electrical Engineering at Stanford.
Prof. Leeson is finishing a book on Bill Hansen’s career and contributions.

Richard Winkler, Stanford Engr ’53.
Winkler worked on high-power klystrons at Stanford. He went to Shockley Transistor (became Cleavite) just after Noyce and Moore left, and was the first regular employee at SLAC, designing equipment to test the 50-MW klystrons, did klystrons for first medical uses of linear accelerators.

Dr. Allen Odian, PhD from MIT, Fulbright Scholar, Assoc Prof at Univ of Ill.
Dr. Odian joined SLAC in 1961 and was involved with detectors.

Prof. Burton Richter (tentative), Physical Sciences, Stanford, and Director Emeritus at SLAC
Prof. Richter began post-doc work at Stanford in 1956, becoming a professor in 1967, and designed the Stanford Positron-Electron Accelerating Ring (SPEAR). He succeeded Wolfgang “Pief” Panofsky as director of SLAC in 1984.  He shared the 1976 Nobel Prize in Physics for his work on the particle that has been dubbed J/psi.

Paul Wesling will moderate this meeting.

In 1956 Lockheed moved its new division, Lockheed Missile Systems Division to a 275 acre site next to Moffett Field in Sunnyvale; Lockheed had been selected as the systems manager for the Navy’s Polaris Fleet Ballistic Missile and the developer of the missile itself. Lockheed in Silicon Valley went from zero employees in 1956 to more than 28,000 by 1965, far greater growth than HP or Fairchild – perhaps it should have been “Defense Valley,” but that’s another story. Polaris was the first submarine launched ballistic missile in the US’s triad of nuclear defense systems. Extended thru four production generations (Polaris A1, A2 & A3 and Poseidon C3) it was retired from service in the early 1990s. They were followed by Trident I C4 and today’s Trident II D5.  Polaris/Poseidon and Trident, collectively known as the US Navy fleet ballistic missiles recently celebrated a sixtieth anniversary and  they are generally recognized as one of the most successful military industrial programs.

Join four Lockheed senior leaders from then to get a retrospective on Defense Valley of the 1950s and 1960s and the Polaris/Poseidon program that led to today’s Tridents than make up the most secure leg of the strategic Triad.

VIDEO of Presentation


Dave Montague a forty year Lockheed employee retired in 1996 as the President of the Missile Systems Division and a Corporate Vice President.  He came to Silicon Valley in 1957 as an engineer on the new Polaris program and progressed up the supervisory and management chain in guidance and control, systems engineering, and program management positions on Polaris, Poseidon, Trident 1, to executive management of Tactical and Defense systems and Trident II as well as several compartmented programs. He is a fellow of the AIAA and a member of the National Academy of Engineering.  He graduated from Cornell University in 1956

Cliff Kancler  a forty two year Lockheed employee retired in 2007.  Starting in 1965 in Silicon Valley with work on the first digital flight control computer Cliff was a major contributor in computer architecture development for guidance computers and for tactical and defense interceptor computers.  In addition to being part of our strategic defense systems computers from Cliff’s group are circling the solar system and have helped explore the moon.  He has earned recognition as a LM fellow and has a number of patents, and awards. He graduated Rensselaer Polytechnic Institute (RPI) in 1965.

Roy Dreisbach a thirty seven year Lockheed employee retired in 1997.  Upon graduating Menlo College in 1960 Roy joined Lockheed and held senior administrative assignments in Missile Systems, Research and Development, Advanced System, and Space Systems Divisions spanning programs such as Polaris A1 through Trident II as well as Tactical and Defense Systems.  He is an ex-naval aviator, having flown Lockheed Super Constellation early warning aircraft from 1954 to 1958.

Charlie Barndt is a forty eight year Lockheed Martin active employee. Upon graduating from Cornell University in 1965 Charlie joined General Electric as an engineer on Polaris and Poseidon. In 1967 he joined Lockheed as an engineer on Poseidon and Trident I.
