Alfred Denny

Born in Leeds in 1847, Alfred Denny came from a natural-history family: his father, Henry Denny, was a noted entomologist and museum curator. Alfred later moved into academic life and joined Firth College in Sheffield in 1884, where he taught biology and remained for decades.

He became professor in 1888 and, when the University of Sheffield received its charter in 1905, served as its first professor of biology. He was also closely connected with the university’s teaching collections, helping promote the idea of a museum where students could learn by studying real specimens and their evolutionary relationships.

As an author, he is best remembered for zoological works including The Structure and Life-history of the Cockroach, written with L. C. Miall. His books reflect the strengths of his career: careful attention to structure, habits, and development, and a talent for turning zoology into something vivid and teachable.
