Hall of Fame inductees are nominated by current Glenn employees and then chosen by committee. This year’s induction coincides with Glenn’s 80th anniversary.

The 2021 class includes:

Bruce Banks – Glenn’s most patented researcher and champion of technology transfer. Banks grew up in Rocky River and now lives in Olmsted Falls, Ohio.

Olga Gonzalez-Sanabria – Leader in battery research and project management and the center’s first Latina senior executive. Sanabria lived in Strongsville, Ohio, while working for NASA. She was born in Puerto Rico and lives there today.

Dr. Henry Kosmahl – Pioneer of traveling wave tube technology whose work led to the center’s emergence as a leader in space communications. Born in Germany, Kosmahl lived in Olmsted Falls, Ohio, and passed away in 2011.

Dr. Patricia O’Donnell – Leader in high-energy propellants, energy conversion, and batteries, and Glenn’s first patented female inventor. She lives in North Olmsted, Ohio.

The NASA Glenn Hall of Fame was established in 2015 to recognize individuals who had a lasting influence on the direction and mission of the center, made fundamental advancements in their field, or served as an inspiration to employees though their character and embodiment of the NASA spirit.

A ceremony for this year’s inductees will take place in 2022 due to the ongoing pandemic.
