Schaefer, Vincent J(oseph) (1906–1993)

US meteorologist. Schaefer worked with Irving Langmuir at General Electric. During World War II they designed an efficient smoke generator to screen military operations and improved the filter for gas masks. In the course of his research, he became accidentally involved in cloud seeding, resulting in the government sponsored ‘Project Cirrus’. He was later instrumental in establishing the Atmospheric Sciences Research Center.
