In honor of International Women’s Day 2019, on March 8, 2019, BRIT Library highlighted the botanist Mary Sophie Young. As one of the earliest botanists at University of Texas, Mary Sophie Young’s extensive collecting throughout Texas greatly contributed to the flora of Texas as well as the holdings of the University of Texas herbarium. The estimated number of her collection is thought to be in the vicinity of 10,000. Young was born in Glendale, Ohio, in 1872. She earned her B.A. at Wellesley College in 1895 and her PhD from the University of Chicago in 1910. In 1912, she became the curator of the University of Texas at Austin herbarium as well as a faculty member in the botany department.
