Oh, Lou!

Happy birthday to Lou Henry Hoover, who, if she were living, would be 138 years old today.
Despite being married to one of history's most maligned ex-presidents, Lou Hoover was an extraordinary woman.
She was the first woman to major in geology at Stanford University.
Lou Hoover was the only First Lady to speak Chinese and could also speak five other languages.
She was the first First Lady to broadcast on radio.
She and her husband translated Agricola's De Re Metallica, a 16th century encyclopedia of mining and metallurgy from its original Latin.
Mrs. Hoover was instrumental in establishing the Girl Scouts as an American organization. She was a troop leader in D.C. in 1917 for a deliberately racially integrated troop.
Her future husband, Herbert Hoover, proposed to her via telegram when she was studying abroad in Australia. She accepted via reply telegram.
