Acc.#1998.0191 Danko - Introduction AC#667

Danko 1998.0191  Stanislaus (Stan) Francis Danko was instrumental in the development and invention of ©AUTO-SEMBLY; as well as the designer for flexible circuits, and the solder dipped circuit process. This process was subsequently patented by the US Army and immediately adapted by both military and industrial designers.

Danko also kept calendars for each year with copious notes regarding developments of particular designs, engineering, and reference to significant personalities involved with his (and others') work. References are scattered throughout these calendars as well as equations and sketches.

The Danko Collection represents very early discrete transistors as well as pre and post 1958 technology. The NMAH Archive Collection includes a complete biography: A Career In Perspective, 1916-1969 of Danko and professional publications supporting Danko's work in integrated circuit technology.
