Series I. General Electric Company Proposals, 1966-1986

Arranged chronologically by date, this series contains twenty-seven General Electric Company proposals that were collected and maintained by Adelbert T. Tweedie. The proposals preserved in this series are for projects Tweedie worked on at General Electric Company’s Missile and Space Division and the division's successors between 1966 and 1986.

A majority of the proposals in this series were prepared for the National Aeronautics and Space Administration (NASA) and the United States Air Force. A handful of proposals for other federal government agencies, including the United States Department of Health, Education and Welfare (HEW), the National Science Foundation, and the Energy Research and Development Administration are also preserved here.

A large majority of the proposals in this series concern materials developed for space flight applications. A handful of proposals for materials developed for other purposes, including medical applications, energy storage, and energy generation are preserved here as well.
