Information Technology (IT) Pioneers

Retirees and former employees of Unisys, Lockheed Martin, and their predecessor companies

Our Legacy Chapters

Our Legacy theme consists of People Engineering Systems and Computers at Locations in the Minnesota Twin Cities environs and throughout the world. These chapters are an on-going web site anthology, now a decade long innovative approach to document and publicize our Information Technology (IT) industry pioneering history.  The 'Our Stories' and 'Exhibit Sites' chapters complement and supplement the Legacy topics theme of this site. In addition to the navigation buttons at the left, the chapter select links immediatly at the left have corporate threads, important milestones, etc.  the Site Map has an ANTHOLOGY Table of Contents
    In late 2005, Lockheed Martin Corporate, motivated by the realization that their current company was created from over 20 predecessors, asked their various operating units to “capture their legacy” without a real concept of what was to follow.  In Eagan Minnesota, Ole (Dick) Olson was tasked to respond; he formed an ad hoc group of employee volunteers and then contacted the VIP Club Board to form a Legacy Committee. [lab]
    "The committee quickly realized that the history of Engineering Research Associates (ERA), continuing to the present, was a remarkable story of technological innovations and contributions to the computer industry in general and specifically Minnesota.  This story, particularly the early years, has never really been completely told; e. g. the ATHENA computer launching over 300 missiles at the beginning of the space age - with never an abort caused by the computer system!
    To be sure, there are some accounts written from the business history perspective, from various customer and user perspectives, and partial documentation in many places.  However; we are unaware of any account, which properly gives credit to the ingenuity, vision, and hard work of ERA and its successor company employees, and their contributions to Minnesota and the world.  The legacy committee feels that it would be a terrible loss not to capture the full history, thus inspiring our efforts to determine just what can be accomplished.  There is a bit of urgency, as the memories and materials relating to the ERA beginnings are disappearing rapidly.  Our pioneers are dying, successor corporations are shredding records, and memories are fading."
By Harvey Taipale - November 2007.

BTW & FYI:  From the CBI Fall 2018 newsletter:  "Over the past year Charles Babbage Institute staff, a University of Minnesota History of Science, Technology, and Medicine (HSTM) doctoral student and an HSTM postdoc collaborated with the Minnesota High Technology Association, the Dakota County Historical Society, Twin Cities Public Television (the local PBS affiliate), the VIP Club (a local IT retirees group), and industry veterans (especially Rich Daly and Dale Weeks), to conduct a major research and public history project on computing history in Minnesota. This has been a very rewarding partnership, and we have just completed this important one-year project, funded by the state of Minnesota through the program, which is administered by the Minnesota Historical Society."

A Google Search Box is provided for your use in searching this site with over 60 Legacy chapters.

 Foremost throughout this Legacy are the people; most now enjoying retirees' camaraderie; others still working at UNISYS, LMCO, and other high-tech companies in Minnesota and throughout the world; and so many who have passed away.  
   During our Legacy, a few management and engineering personnel left to form other companies (spin offs), most notable was the 1957 creation of Control Data Corporation (CDC) led by Bill Norris, et al'.  Seymour Cray joined him, then later left CDC to establish the the super computer company "Cray".  This site mentions those computer industry pioneers but does not detail their careers outside of this ERA Legacy.  Several threads weave their way through these corporate ownerships:

  • People Performing in Partnership with customers to solve complex system information and control problems!
  • A resilient cadre of management and engineering personnel, some with military training/experiences, applied to understanding the problems facing government and business customers.
  • Systems for processing of real-time signals and data from radar, sonar, satellites, and other sensor sources to provide users with operational information and action options.
  • Computer Instruction Set Architectures (ISA) normalized over several product line generations.
  • Availability of technology researchers and new graduates from the world-class Institute of Technology [now the College of Science and Engineering' (CSE)] at the University of Minnesota (U of MN) and other Midwest colleges.


The committee began at the October 2005 VIP Club board meeting. Ole [Richard D. Olson] representing Lockheed Martin Company (LMCO) and Lowell Benson representing the Club volunteered to be co-chairs.  Dick Lundgren immediately volunteered to support the committee.  Then Dick made arrangements for us to meet with Dr. Norberg at the Charles Babbage Institute.  Dr. Norberg told us that we should do oral interviews and that if we could get 200 mini-bios from people we would have told 'The Story'.  Ole said that he would solicit product/systems development stories and mini-bios.  Lowell started a web site in March 2006 to make the stories and mini-bios public, merged with the VIP Club site in March 2007.  Dick Lundgren said that he would help write and edit stories. 

The Legacy Committee and project set three priority objectives:

  • to capture whatever remaining material and information we can,
  • to catalog and archive all the material collected, and
  • to publish/publicize our history and heritage in a way that interests others within our industry and our fellow Minnesotans.

Our Committee volunteers have given countless hours over the decade: Lowell Benson - Engineering Manager; Bill Bergen - Systems Engineer; Larry Bolton - Component Engineer; Millie Gignac - Human Resources; Bernie Jansen - Engineering Manager; Dick Lundgren - Instructor/Writer; Tom Montgomery, Systems Engineer; Keith Myhre - Systems Engineer & Marketing Manager; Tricia Myhre - Systems Programmer; Les Nelson - Systems Engineer; Bob Pagac - Program Manager; Dan Rogers - Systems Training Director; Jon Simon - Systems Engineer; Ron Q. Smith, UNISYS Fellow; Mike Svendsen - VP of Procurement and Semiconductor Development; Harvey Taipale - Engineering Manager; Earl Vraa - Engineering Manager; Don Weidenbach, Engineer & Manager; and John Westergren, Program Manager.

We've had steadfast archiving support and guidance from first Dr. Norberg then for over a decade from Dr. Thomas Misa  and now Dr. Jeffrey Yost and the staff at the Charles Babbage Institute at the University of Minnesota. Appropriately, the CBI Director holds the Engineering Research Associates Land Grant Chair for the History of Technology position endowed by private donations.

Sadly, many of our contributors/pioneers have passed away during our Legacy initiative: Warren Becker, Warren Burrell, Quint Heckert, Bill Klingner, Edwin Nelson, Richard 'Ole' Olson, Jim 'Rapp' Rapinac, Jack Sater, Marc Shoquist, Tom Turba, Harry Weis, Paul Welshinger, ...

Legacy Anthology Chapters by Retirees, et al'

Our corporations employed People who Engineered Systems and Computers in Locations locally and throughout the world, thus the Legacy chapter titles, structure, and theme of this web site. When we eventually write a book, because of the physical size, i.e. printed page count, we may have to publish the history as volumes.

  • People - Over 250 project experiences and career summaries from and or about the people who have experienced parts of this Legacy.
  • Engineering - Our designs transition all electronic generations; vacuum tubes, transistors, integrated circuits, micro-processors, application specific integrated circuits, etc. We've included Software, Field Service, Training, Antenna Couplers, Patents, Peripherals, and Interfacing chapters or subsections.
  • Systems -Aerospace, Airborne, Naval Tactical Data Systems, Air Traffic Control, Marine Systems, Air Force, ASOC, Government, and Commercial since the File Computer systems in the 50s. This century, people would just call them apps.
  • Computers - The world's first stored-program cryptography computer shipped to a customer in October 1950, Aerospace computers, Navy shipboard computers, airborne search computers, ..., embedded micro-processors.
  • Locations - Not only the Twin Cities of Minnesota, but facilities throughout the U.S. and a few overseas sites. Marketing Offices, Technical Services Division (TSD), Canada, etc.  Operations at these sites have yet to be fully documented.
  • Our Stories - Since April 2007 we have been soliciting, editing, and posting stories as the 'Article for the Month'. Some are technology tidbits, some are committee status summaries, a few are duplication of other publications from other organizations used with permission, and some developed in response to questions posed by people who have browsed our site pages/chapters.
  • Exhibits - In January 2013 the Dakota County Historical Society's Lawshe Memorial Museum became the repository and displayer of artifacts collected by the committee since 2006.  This chapter also provides information about other displays of UNIVAC/Sperry/UNISYS/ equipments at museums throughout the United States.
  • Contacts and Links - Many web sites provide heritage related information.  Also, we have provided links to a few 'educational' sites for youth who want to have Science, Technology, Engineering, and Mathematics (STEM) careers. 

No, we did not created a Blog nor Facebook nor Tweet nor Wiki-pedia approach because we want to assure accuracy of information and identification of the source of information.  BUT, we do welcome reader inputs.

Thank You to:

  Thanks to the 300+ retirees, active employees, customers, and former equipment users who have contributed to our Legacy A anthology. Thanks to staffs of the Charles Babbage Institute (CBI) and the DCHS Lawshe Memorial Museum for their guidance and support as we have and are sorting and cataloguing hundreds of 3-D artifacts and thousands of 2-D papers and photographs. Among our artifacts are several hundred 'Code Cards' which have been donated to CBI with some copies at the Lawshe Memorial Museum. PDF copy links to these code cards are on our computer chapters, software chapter, peripherals chapter, etc.
   We appreciate the efforts of the Computer History Museum, located at 1401 N. Shoreline Blvd Mountain View, CA 94043. They have a number of artifacts from Univac including a 642B computer as part of their NTDS exhibit. They also facilitate the site where there are pdf files of many UNIVAC/Sperry/UNISYS manuals and brochures among their 32,000 electronic items.

A special thanks to Dr. Tom Misa - Director, Charles Babbage Institute at the University of Minnesota - From 2007 into 2017, Tom has been an advisor to our Legacy committee giving valuable advice on what to preserve and how to do some of that preservation. He developed a book, The Digital State, incorporating some of our committee findings and references some of our web pages in his Technology History Class lectures.
