Rad Lab in Building 20 at MIT, Cambridge, MA, 1943 (via MIThistory)
“Building 20 at 18 Vassar Street was a temporary wooden structure hastily erected during World War II on the central campus of the Massachusetts Institute of Technology. Since it was always regarded as “temporary”, it never received a formal name throughout its 55-year existence. The three-floor structure housed the Radiation Laboratory (or “Rad Lab”), where fundamental advances in physical electronics, electromagnetic properties of matter, microwave physics, and microwave communication principles were made. After the Rad Lab shut down after the end of World War II, Building 20 served as a “magical incubator” for many small MIT programs, research, and student activities for a half-century before it was demolished in 1998.”
