MIT’s Building 20, built in 1943,was called the “Magical Incubator” because over the course of its long history it housed a range of laboratories involved in some of the most important and ground-breaking developments in science and technology, from acoustics to radar. This short piece was produced to share at the March 1998 commemoration that gathered former tenants of the building before its demolition in 1998 to make way for the Ray and Maria Stata Center. An exhibit showcasing its history can be enjoyed within the Stata Center (Bld. 32). [T #?]
