David Keller Caldwell

Born in 1928 and active through the mid-20th century, he was an American zoologist whose research centered on marine biology, especially fishes and marine mammals. Bibliographic and authority records identify him as David Keller Caldwell, and published work linked to his name shows a career that moved across ichthyology, cetacean studies, and field-based natural history.

His writing reached both specialists and general readers. He coauthored Whales, Dolphins, and Porpoises of the Western North Atlantic, a widely circulated identification guide, and he also published on subjects such as bottlenosed dolphins, Amazon river dolphins, Caribbean small-whale fisheries, and fish species from places including Bermuda and Jamaica. Records from GulfBase describe him as a curator of ichthyology at the Los Angeles County Museum of Natural History, reflecting the breadth of his scientific work.

Available records indicate that he died in 1990. Even in brief library and archival listings, his legacy stands out for connecting careful zoological research with books and articles that helped readers better recognize and understand life in the sea.
