Josiah Gregg was an American merchant, explorer, naturalist, and author of Commerce of the Prairies, about the American Southwest and parts of northern Mexico. He collected many previously undescribed plants on his merchant trips and during the Mexican-American War, for which he has often been credited in botanical nomenclature. After the war he went to California, where he reportedly died of a fall from his mount due to starvation near Clear Lake on 25 February 1850, following a cross-country expedition which fixed the location of Humboldt Bay.
