At the start of World War II, the US government bought the estate of Timothy Hopkins from his widow and created the Palo Alto General Hospital, later renamed the Dibble General Hospital (after Colonel John Dibble, who was killed in 1943). After the war ended, some of the land was sold to the city and became the sites of the main library and city hall. More of the land was bought by Stanford University to house the increase in students due to the G.I. Bill; the area was known as the "Stanford Village", which existed as student housing until the mid-1960s. This land also was the site of the Stanford Research Institute (now SRI International) starting in 1947; between 1955 and 1968, SRI bought the rest of the Stanford Village.
