Project Cirrus, 1891-1985, Undated

Extent:
4.25 cubic ft.
Scope and content:

This series documents the Project Cirrus program, a weather modification initiative undertaken by GE along with the United States Signal Corps, Office of Naval Research, and the United States Air Force, with general oversight handled by the Department of Defense. As part of the effort, Dr. Vonnegut discovered that AgI, Silver Iodide, was a superior nucleation agent. This discovery significantly influenced the science of artificial precipitation and this method came to be adopted as the chief means of "rain making".

The series contains the research, data, reports, correspondence, publicity, and photographs regarding the project. Please note that the archivist filed all of the loose photographs together. The archivist kept any photograph accompanying research, data, or reports with that respective material.
