Finding for the Charles W. Yodzis Papers (HSF-71)

The Charles W. Yodzis Papers is composed of correspondence, memorandums, organizational charts, handbooks, manuals, technical reports, technical drawings, handwritten research and calculations, engineering performance studies, general propulsion studies, research files, notes, scientific studies, presentation slides, staff lists, photographs, 35mm slides, directories, magazine issues, and miscellaneous materials, created, used, or collected by Charles W. Yodzis from 1957 to 1994. Yodzis served as the Chief of the Primary Propulsion Branch of the Propulsion and Power Division at NASA Johnson Space Center from 1964 through his retirement. Most of the materials were used by Yodzis in his research and design for the engine systems for the Apollo Command Service Module and Lunar Module, and for the Space Shuttle Orbiter—for which he and his team were primarily responsible for developing. The collection consists of materials stored in Yodzis’ original office subject and research files by project, purpose, engine type, and mission names. The collection is unique in that there is a large amount of Yodzis’ original handwritten scientific calculations and notes on all aspects of the development of primary propulsion systems for spacecraft.
