Gustave Toudouze, naturalist, was born on April 24, 1819, in Noyent, France. In 1839 he married Josephine Perot. He was a professor of natural history before immigrating to Tennessee in 1846. In 1853 he moved to Losoya, Texas, where, as a taxidermist and natural scientist, he built up a museum consisting of birds, birds' eggs, wild animals, flowers, and rocks. With his close friend, Henry P. Attwater, a Canadian naturalist, Toudouze exhibited an extensive collection of Texas mammals and birds at the World's Industrial and Cotton Centennial Exposition in New Orleans in 1884 and 1885. He died at Losoya on May 8, 1902.
