    Ronald Leighton McGregor
    1919–2012
    R
    onald Leighton McGregor, Curator Emeritus of the
    Ronald L. McGregor Herbarium at the University
    of Kansas, died April 21, 2012, at the age of 93. Born in
    Green, Kansas, on April 4, 1919, he graduated from high
    school in Oregon, Missouri, in 1937. He received his B.S.
    degree in botany from the University of Kansas in 1941
    and started graduate studies at KU that same year. He
    served in the U.S. Army from 1942 to 1946, stationed
    most of that time in the Pacific Theater.
    Ron resumed his graduate studies at KU in 1946,
    completing his M.S. in 1948 and Ph.D. in 1954. He was
    promoted to Assistant Professor at KU in 1954, when he
    also took over directorship of the herbarium, then with
    about 70,000 specimens. He was promoted to Associate
    Professor and Chair of the Department of Botany in
    1957 and to Professor in 1961. He administered the construction of a new botany greenhouse and a new herbarium building on KU’s West Campus in the early 1960s.
    Around that same time, he initiated systematic efforts to
    document the plants of the Great Plains with financial
    support from the Bridwell Foundation. The Foundation
    helped underwrite field expeditions to every county in
    the Great Plains, garden plot studies of range grasses,
    and specimen preparation into the 1980s.
    Ron continued to serve as Chair of Botany until 1969,
    when he became the first Chair of the Department of
    Biological Sciences. He continued in that capacity until
    1973. From 1955 to 1973, he advised 21 M.A. and 19
    Ph.D. students, many of whom went on to careers in
    academia and science. In 1971, he helped convene a
    meeting of Great Plains botanists. That group formally
    organized as the Great Plains Flora Association in 1973,
    with Ron serving as the coordinator. The Association
    published the Atlas of the Flora of the Great Plains in
    1977 and the Flora of the Great Plains in 1986.
    From 1973–1983, Ron served as Director of the
    Kansas Biological Survey. In 1984, with funding from
    the Bridwell Foundation, he oversaw construction of
    an annex to the herbarium building; the entire building
    was named the Joseph S. Bridwell Botany Research
    Laboratory in 1985. Ron continued to serve as Professor
    and Curator until 1989. At his retirement in 1989, the
    herbarium had grown to nearly 300,000 specimens. In
    1990, the collection formally was named the Ronald L.
    McGregor Herbarium and “dedicated to the study of the
    Great Plains flora.”
    Ron authored nearly 200 papers and books during
    his career and collected nearly 42,000 specimen numbers
    in the U.S. and Mexico. His duplicate specimens are
    widely distributed among North American herbaria and
    frequently cited in the literature. He served as a regional
    reviewer for the Flora of North America project, putting
    his prodigious knowledge of Great Plains plants to good
    use. He also authored treatments for five genera in
    Hydrangeaceae; those will be published posthumously
    in Volume 12. He was active at various times in more
    than a dozen professional organizations.
    Ron continued to work in the herbarium nearly every
    day after retirement until April 2009. On rare occasions
    when he took time off from the herbarium, he enjoyed
    fishing and working in his garden. Ron was keenly interested in Kansas history, and he had an encyclopedic
    memory for dates, places, people, and events. He is
    survived by his wife of 70 years, Dorothy M. McGregor.
