Born in Missouri Valley, Iowa, on March 24, 1879, Brayton Howard Ransom studied at the University of Nebraska, earning degrees in 1899, 1900, and 1908. He went on to build his career in federal science, serving with the United States Department of Agriculture and eventually leading the Zoological Division of the Bureau of Animal Industry.
Ransom became especially known for his work on parasitic nematodes and tapeworms affecting animals. Sources describe him as an important early figure in American parasitology, and he was also among the founding members of the American Society of Parasitologists.
He died in Washington, D.C., on September 17, 1925, at just 46 years old. Even in a relatively short life, he left behind a large body of scientific work and a reputation for advancing veterinary parasitology in ways that mattered both to researchers and to the livestock industry.
