Born in Missouri Valley, Iowa, on March 24, 1879, Brayton Howard Ransom studied at the University of Nebraska, earning bachelor's and master's degrees before later completing a Ph.D. He also studied medicine at George Washington University and became known as a specialist in medical zoology.
Ransom spent most of his professional life with the United States Department of Agriculture's Bureau of Animal Industry. From 1906 until his death in Washington, D.C., on September 17, 1925, he served as chief of its Zoological Division, building a reputation as one of the country's leading experts on animal parasites.
He is especially remembered for research on parasitic worms, including important work on nematodes and tapeworms that affected livestock. Though he died at just 46, his studies helped lay the groundwork for modern veterinary parasitology and for a better scientific understanding of diseases that carried major economic costs for farmers.
