Willard J. Gertsch: A Renowned Arachnologist

Willard James Gertsch, a prominent American zoologist and arachnologist, was born on October 4, 1906, in Montpelier, Idaho, to Swiss-born parents Paul and Louise Sarbach Gertsch.

Early Education and Influences

Gertsch pursued his higher education at the University of Utah, earning his bachelor's degree in 1928 and a master's degree in 1930. He then embarked on doctoral studies at the University of Minnesota, where he met two influential figures: renowned entomologist Frank E. Lutz, who became his mentor, and his future wife, Jean Elizabeth Moore.

Marriage and Family

On August 20, 1932, Gertsch and Jean Moore were married in Duluth. They had three children: daughters Louise (b. July 25, 1934) and Mary Alice (b. August 6, 1945), and a son, John (b. May 24, 1936).

Career at the American Museum of Natural History

Through the recommendation of Frank E. Lutz, Gertsch joined the American Museum of Natural History as an Assistant Curator in 1935. He received his Ph.D. degree that same year for his dissertation on Nearctic crab spiders of the subfamily Thomisinae. Gertsch served as Curator of Arachnida and Arthropoda at the museum until his retirement in 1968.

Later Years and Legacy

After retiring, Gertsch settled in the Chiricahua Mountains of southeastern Arizona, where he continued his arachnological research. His home became a gathering place for arachnologists, inspiring the establishment of the American Arachnological Society in 1972. Gertsch played an instrumental role in the organization as a board member and editor of the Journal of Arachnology.

Impact and Recognition

Throughout his career, Gertsch described approximately 1000 new species of spiders and other arachnids. His groundbreaking work advanced the field of arachnology and earned him widespread recognition. In 1965, he was awarded the Thomas Say Award by the Entomological Society of America for his outstanding contributions to insect taxonomy.
