Mary Agnes Chase (1869-1963) was known for her study of grasses. Because it was inappropriate for women to conduct field work, she often personally funded her own research trips. Chase joined the Department of Agriculture as a botanical illustrator in 1903. By 1935, she was Principal Botanist at the United States National Museum. With numerous awards, including a Certificate of Merit issued by the Botanical Society of America in 1956, Chase was recognized for her work as an agrostologist.
