Herbert Hoover was a highly accomplished mining engineer, businessman, and humanitarian before he had the bad luck to be inaugurated as President of the United States shortly before the outbreak of the Great Depression. He then had a long post-Presidential career, living all the way until 1964.
Hoover married well. Lou Henry Hoover, First Lady of the United States, met her future husband while they were students at Stanford University. She had a sharp mind and became the first woman to graduate from that institution with a degree in geology.
Lady Hoover was a polyglot and, like her husband, had an education in the Latin language. Together, they translated De Re Metallica, a historically important Sixteenth Century Latin text by Georg Bauer about mining and metallurgy. After several years of labor, Herbert and Lou Hoover created the first English translation of the work, making use of their expertise of both geology and Latin. It remains the definitive English translation to this day.
