1889–1964
Best known for decades of fieldwork and research on African birds, this American ornithologist helped turn firsthand expedition notes into one of the landmark references in his field. He also spent much of his career at the American Museum of Natural History, where he worked as a curator and researcher.
Born in New York City on July 9, 1889, he became one of the leading American ornithologists of the 20th century. His name is closely tied to central Africa, where he joined the American Museum Congo Expedition as a very young assistant and built the deep firsthand knowledge that shaped his later work.
He spent his professional life at the American Museum of Natural History, serving as a curator and focusing especially on the birds of the African continent. His best-known achievement is The Birds of the Belgian Congo, a major multivolume work published over many years and long regarded as an essential reference for African ornithology.
He died in New York City on April 5, 1964. Remembered for combining careful museum scholarship with demanding expedition work, he helped expand scientific understanding of African birdlife in a way that lasted well beyond his lifetime.
