Lou Henry Hoover (March 29, 1874 - January 7, 1944) served as First Lady of the US from 1929-33. She was a fine horsewoman, who hunted, and preserved specimens with the skill of a taxidermist. In 1894 she enrolled, as the school's only female geology major, at Stanford University, where she met Herbert Hoover. Marrying her engineer husband in 1899, she traveled widely with him, and became a cultivated scholar and linguist. In the White House the Hoovers would sometimes converse in Chinese to foil eavesdroppers. To date, she is the only First Lady to speak an Asian language. She distinguished herself by becoming the first First Lady to broadcast on a regular basis. Although she did not have her own radio program, she participated as a guest speaker on a number of occasions, often advocating for volunteerism, or discussing the work of the Girl Scouts. She collaborated with her husband in translating Agricola's De Re Metallica, a 16th century encyclopedia of mining and metallurgy. The Hoover translation was published in 1912, and remains in print today as the standard English translation. She died of a heart attack in 1944 at the age of 69.
