What subject did A. A. Milne study at Cambridge University?

A. A. Milne studied mathematics at Cambridge University.

He attended Trinity College on a mathematics scholarship and graduated with a Bachelor of Arts degree in 1903. His academic subject was very different from the children’s fiction that later made him famous.

Milne’s early professional life centered more on journalism, humor and theater than on mathematics. He wrote for Granta and became associated with Punch before the success of the Pooh books transformed his public reputation.

People sometimes assume Milne studied English because he was a celebrated writer. His formal university subject was mathematics, although his interest in writing was already visible during his student years.
