John Thomas Baldwin
John Thomas Baldwin Jr. (September 5, 1910 – September 3, 1974) was an American botanist. He specialized in cytogenetics of plants and in his early career studied the family Crassulaceae. In 1946 Baldwin was appointed professor at his alma mater, the College of William & Mary. He also worked for the US Department of Agriculture, accompanying their expeditions to Africa. During the 1947–48 US Economic Mission to Liberia Baldwin discovered that "Strophanthus sarmentosus" was a natural source of the steroid hormone cortisone and it was subsequently used for the manufacture of drugs. He planted an extensive collection of plants on the college campus, which later botanists claimed to be one of the most important in the country. After Baldwin's death, the college donated land to form a memorial park in his honor.
