Lou Henry Hoover

Lou Henry Hoover (née Henry; March 29, 1874 – January 7, 1944) was an American philanthropist, geologist, and the first lady of the United States from 1929 to 1933 as the wife of President Herbert Hoover. She was active in community organizations and volunteer groups throughout her life, including the Girl Scouts of the USA, which she led from 1922 to 1925 and from 1935 to 1937. Throughout her life, Hoover supported women's rights and women's independence. She was a polyglot, fluent in Mandarin Chinese and well-versed in Latin, and was the primary translator from Latin to English of the complex 16th-century metallurgy text De re metallica.

Hoover was raised in California while it was part of the American frontier. She attended Stanford University, and became the first woman to receive a degree in geology from the institution. She met fellow geology student Herbert Hoover at Stanford, and they married in 1899. The Hoovers first resided in China; the Boxer Rebellion broke out later that year, and they were at the Battle of Tientsin. In 1901 they moved to London, where Hoover raised their two sons and became a popular hostess between their international travels. During World War I, the Hoovers led humanitarian efforts to assist war refugees. The family moved to Washington, D.C. in 1917, when Herbert was appointed head of the Food and Drug Administration, and Lou became a food conservation activist in support of his work.
