Winslow, Lorenzo Simmons, 1892-1976

Lorenzo Simmons Winslow (1892-1976) worked as an architect in the White House from 1933 to 1953, the longest duration of any architect at the White House. While at the White House, he designed the White House swimming pool in the West Terrace for President Franklin D. Roosevelt in 1934, assisted with the West Wing expansion, also in 1934, and designed new roads, gates, and fences on the south grounds in 1936. He designed a new White House kitchen and pantries in the residence, and new work spaces for carpenter and paint shops under the north grounds in 1937 and 1938. Also in 1938, he oversaw changes to the ground floor White House Library for President Roosevelt. Winslow was appointed official White House architect in 1941 and assumed responsibility for the design and construction of the East Wing in 1942. At President Harry S. Truman's request, Winslow oversaw the addition of the Truman Balcony to the South Portico and in 1948 was named architect-in-charge of the renovation of the White House that continued until 1952. He retired to Florida in 1953.
