Carter Clarke. See this article: https://www.wired.com/2003/09/diamond/

For anyone else googling this like I just did, Carter Clarke Jr. is the Gemesis founder.

Took me longer than I care to admit reading the Wikipedia page for Carter Clarke Sr. (also a brigadier general) who led a pretty interesting life of his own (e.g. leading the War Department investigation of Pearl Harbor intelligence failures) before I realized I had the wrong generation of Clarkes.
