The VT Fuze
From 1942 to 1945, The Johns Hopkins Applied Physics Laboratory designed, built, and tested a proximity fuze that significantly increased the effectiveness of anti-aircraft shells. Six decades later, with a grant from the National Film Preservation Foundation, APL teamed up with the Johns Hopkins Sheridan Libraries to restore the 1945 Laboratory-produced film, VT Radio Proximity Fuze. The 45-minute, silent color movie shows the development and deployment of the fuze—APL's founding invention, which was judged to be one of the three most valuable technology developments of World War II (along with the atomic bomb and radar).
