Bernard Reich Transistor Museum Historic Profile
Recognizing Significant Contributions to 20^th Century Semiconductor History and Technology
Notable Contributions, Continued
Bernie was the inventor/co-inventor of several key patents relating to early semiconductor technology.  These patents are listed at right.  Several of the patents illustrate the U.S. government/Signal Corps affiliation with Bernie’s work.  For example, as shown in the  patent  above:  (1) The assignee is “The United States of America, as represented by the secretary of the Army”.   (2) The patents state: “The invention described herein may be manufactured, used and licenses by or for the Government for governmental purposes without the payment to me of any royalty thereon”.
