"Botany in the Age of Mendel" suggests the importance of classifying biologists as Botanists or even Mendelians. Many researchers who considered themselves botanists, zoologists, or physiologists, would today be thought of as Geneticists. Barbara McClintock, who is currently identified as a geneticist, was starred in the research subject Botany, in her biographical sketch in the Biographical Dictionary, AMERICAN MEN OF SCIENCE, 1944. The subject, Botany, was one of twelve principle sciences of which the editors chose "men" whose work was supposed to be the most important. The star meant that the entrant was one of the leading students of science of the United States. The first professional organization McClintock is affiliated with is the Botanical Society of America. In 1944, McClintock was elected to the National Academy of Science's Section of Botany. Other notable members of the National Academy of Science, who might currently be considered Geneticists or Molecular Biologist, are A.F. Blakeslee, R.A. Brink, G.W. Beadle, R.E. Clausen, Max Delbruck, E.M. East, and L.J. Stadler, but all were elected to the Academy's Section of Botany. In 1957, McClintock received the Botanical Society of America's Merit Award for Distinguished Achievements in Contributions to Advancement of Botanical Sciences. I will describe McClintock's undergraduate and graduate education as a "Botanist." That preparation, so essential to an understanding of Mendelian heredity in plants, led to the achievements for which she was awarded the Nobel Prize in 1983. I will demonstrate McClintock's role as advisor and Instructor of Botany at Cornell University and as Assistant Professor of Botany at the University of Missouri.
