 Person

Biographical Note

Theodore (Ted) Koch is a donor to the Aircraft Engine Historical Society (AEHS).

Biographical Information (from 7 September 2025 email): "In my early career I worked as a Pratt & Whitney Aircraft [P&WA] experimental test development engineer. I developed and tested engines and [engine] components, and [was part of] the fuel cell development for the Apollo Space Program. I was part of the launch team for the first six Apollo launches at KSC [Kennedy Space Center, Cape Canaveral, Florida].

As a P&WA Area Director, I became a customer technical representative covering Africa, the Middle East and the Indian subcontinent.

After retirement from P&WA, I contracted to Martin-Marietta [Company] to develop and implement a Customer Service Department for their recently purchased engine nacelle manufacturing program.

Later I became a supplier to antique aircraft refurbishers making unique individual hardware pieces."
