Best known as a Scottish zoologist with a deep interest in crustaceans, he brought museum science and clear, wide-ranging natural history writing together. His work helped make a complicated corner of animal life easier for general readers and specialists alike.

by W. T. (William Thomas) Calman
Born in Dundee in 1871, William Thomas Calman was a Scottish zoologist who specialized in crustaceans. He studied at the University of Dundee and the University of Glasgow, and he went on to build his career at what is now the Natural History Museum in London.
Calman became a leading authority on Crustacea and later served as Keeper of Zoology at the British Museum (Natural History) from 1927 to 1936. Alongside his museum work, he wrote books including The Life of Crustacea, which is still remembered for turning detailed zoology into readable natural history.
He died in London in 1952. For listeners coming to his work now, he stands out as a careful scientific writer from a period when classification, observation, and museum research shaped how many readers first encountered the diversity of animal life.
