John Merton Aldrich (1866-1934) was born in Minnesota. After graduating from South Dakota State University, Aldrich worked briefly for the South Dakota State Agricultural Experiment Station, and then became the first Professor of Zoology at the University of Idaho in 1891. While at Idaho, he worked on many phases of economic entomology and also began work on his catalog of American Diptera, which was published in 1905. In 1913, Aldrich was appointed Entomological Assistant in the Bureau of Entomology, United States Department of Agriculture, and was assigned to the Cereal and Forage Crop Insects Section in Indiana. In 1919, he moved to Washington, D.C., where he worked in the United States National Museum as Custodian of Diptera and Associate Curator of Insects, positions he held until his death.
