William Mitchell Baird Allison (? – 1923) was an Irishman who joined the Staff in 1896, and quickly became senior Mathematics Master. He was respected as a teacher of outstanding fairness and integrity, and was one of the few who were able to maintain discipline without resorting to the cane. He was a natural choice as a Housemaster in 1908, the first of Allison’s House. Allison became Second Master, and was asked to deputise in April 1922 when the Headmaster died suddenly. He declined because of recurrent ill-health, which included a digestive disorder and persistent insomnia, and he died soon after on the 2nd of March 1923. The immense regard in which he was held was demonstrated by the installation of the clock in his honour in the Main Tower.
