Lou Henry Hoover (March 29, 1874 – January 7, 1944) was the first lady of the United States from 1929 to 1933 as the wife of President Herbert Hoover. She was active in community groups, including the Girl Scouts of the USA, which she led from 1922 to 1925 and from 1935 to 1937. She was the first woman to earn a geology degree from Stanford. In the first twenty years of their marriage, the Hoovers lived in several countries; during World War I, they led efforts to assist war refugees. Beginning in 1917, they lived in Washington, D.C., as Herbert became a high government official. In the White House, Lou Hoover dedicated her time as first lady to her volunteer work, though she did not publicize it. Her invitation of Jessie De Priest to the White House for tea was controversial in the South. After Herbert's defeat for re-election in 1932, Lou Hoover continued her work, helping provide refugee support with her husband during World War II, and died suddenly of a heart attack in 1944.
