July 16, 1946

The Canal Zone Biological Area in Panama is put under Smithsonian Institution administration by President Harry S. Truman. The tropical research station, located on Barro Colorado Island and reserved for scientific purposes in 1923, had been set aside by United States Congress in 1940 as a preserve administered by a board on which the Smithsonian had participated. It is later renamed Smithsonian Tropical Research Institute.
