The Engineering Design Revolution - Early CAD

The People, Companies and Computer Systems That Changed Forever the Practice of Engineering

By David E. Weisberg

This book has been over five years in the making and is now freely available on this web site for your personal use. It can be read online or downloaded and printed for your later perusal. If a company wishes to produce multiple copies of specific material, please contact me at the address below.

In return for free access to over 650 pages of material discussing the people, companies and products that made the CAD industry what it is today, I am asking readers contribute whatever they wish to a foundation that means very much to me. In the mid-1990s I lost both of my sisters to cancer. I am sure many of you have also had relatives and acquaintances struck by this disease. I became very active in a non-profit organization in Denver that raises funds for cancer research and patient support. The endowment portion of this organization is called Cancer League of Colorado Foundation. You can either make a check out to the Foundation and send it to me at the address below (U.S. funds only) or contribute through PayPal.

Sit back and enjoy a trip through the nearly 60 years that totally revolutionized the practice of engineering design. One final word before you start if you find any errors in this material or take issue with what I have written, please let me hear from you. Also, if you have photographs or illustrations you would like to see incorporated into this document, please forward them to me. Having this book online results in a dynamic document that I will update as needed in the future.
