William Dunn (1859-1934) was a mathematician and structural engineer with a flair for design in concrete. One of the first exponents of reinforced concrete, he acted as chief advisor to the British Office of Works on the use of it. During his working life, Dunn made a special study of dome construction and was consulted about repairing the dome of St. Paul's Cathedral. He spent most of his later years in Kenya.
