Biography

Rolla Milton Tyron Jr. was born August 26, 1916, in Chicago. His father was an American history and education professor at the University of Chicago.[2]

Tyron's first scientific paper was published in 1934 on the ferns in Chesterton, Indiana where his family’s summer cottage was located. In 1935, he received an A.A. degree and in 1937 his B.S. both from the University of Chicago. He enrolled in the University of Wisconsin for a Ph.M., graduating in 1938. He attended Harvard, earning both an M.S. in 1940 and a Ph.D. in 1941.[2] While at Harvard, he was influenced heavily by Merritt Lyndon Fernald and Charles Alfred Weatherby.

During World War II, he worked as a lab technician in the U.S. Chemical Warfare Service at the Massachusetts Institute of Technology. After the war, he returned to teaching at Dartmouth College and the University of Wisconsin, where he met his future wife and lifelong collaborator, Alice Faber, a student at the time. In 1947, Tyron joined the faculty at Washington University in Saint Louis as an associate professor of Botany and became assistant curator in the herbarium of the Missouri Botanical Garden.[2]

Tyron left Missouri in 1957 to travel with Alice to Peru and study fern flora of the American tropics. When they returned, Tyron became a research associate at the University of California Herbarium at Berkeley. In 1958, Tyron returned to Harvard as Curator of Ferns at the Gray Herbarium where he remained with his wife until 1987. In 1972, he became a professor of biology at Harvard and supervised pteridologist graduate students.[1][2]

The couple wrote a complete survey of ferns, Ferns and Allied Plants: with Special Reference to Tropical America, with emphasis on tropical America, which was published in 1982.[2][3]

He was a member of the American Fern Society for 69 years, starting in 1932, and held various roles in the society including curator and librarian of the library and herbarium from 1946 to 1957; president from 1974-1975; and was made an honorary member in 1978.[2][4] At the New England Botanical Club, he was recording secretary from 1964-1968, associate editor of the Society’s Journal Rhodora from 1961-1977, editor-in-chief from 1977-1981, vice-president from 1984-1986 and president from 1986-1988.[2] In 1984, he received a Merit Award from the Botanical Society of America.[4]

Following his Harvard retirement, he became an adjunct professor at the University of South Florida in Tampa. He died August 20, 2001.[2]
