William Trelease was born in Mount Vernon, New York in
1857. In his teens he was briefly apprenticed in a machine
shop, but in 1877 he decided to enter Cornell College and
study the natural sciences. After Cornell, he taught at the
University of Wisconsin, and planned to study bacteriology
there; but when he was offered the director's job at the St.
Louis Botanical Garden, he accepted. It was an ideal
position for Trelease, a gifted botanist with a genius for
classifying plants. He directed the 75 acre garden for 23
years, during which time he identified and named 2500
species and varieties of flora. Trelease's botanical
interests were broad: he published a paper on the giant
cactus of Mexico in the same year that he published his
findings about coastal species in Alaska. He studied apple
scab, leaf blight, nematodes.
While on the Elder, he
worked with the others involved in botany, collecting
specimens, but tending to play second fiddle to Muir,
Gilbert and the other, more talkative, scientists. He was
first and foremost a scientist, not a story-teller.
After the expedition, he
returned to St. Louis, and eventually taught at the
University of Illinois. His work includes hundreds of
scholarly papers, but Trelease was not solely an academic.
He published a small, inexpensive set of guides for the
everyday gardener, that remain, to this day, a value for
anyone who wishes to graft an apple tree, or identify and
avoid poison ivy in the winter. Trelease died in 1945.
