June 15, 1910—March 3, 2002
BY TOM L. PHILLIPS
HENRY N. ANDREWS JR. WAS an outstanding pioneer in North American paleobotany during the twentieth century. His explorations of past plant life, especially in the structure, development, and reproductive biology of Devonian and Carboniferous plants, provided benchmark foundations for paleoecological and evolutionary studies. Andrews is noted in part for the discovery of determinate growth in lepidodendrid trees (1958), seminal interpretations of early seed structure and the evolutionary origin of the integument (1963), his advocacy of the significance of seed ferns in gymnosperm evolution toward flowering plants (1948, 1966), and the exploration and evolutionary studies of Devonian plants from the high Canadian Arctic, Maritime Canada, Maine, and West Virginia (1984).
Andrews (1951) recognized early the significance of coal-ball studies in North America. During his years at Washington University (1935-1964) and at the Missouri Botanical Garden (1947-1964) in St. Louis, Henry Andrews contributed, as did his many students, a sustained series of fossil plant studies generally entitled “Contributions to Our Knowledge of American Carboniferous Floras,” published in the Annals of the Missouri Botanical Garden.
