Commander Archibald Bruce Campbell (21 January 1881 – 11 April 1966) was a British naval officer and radio broadcaster, born in Peckham, London.

He survived its sinking off the island of Islay in October 1918 after it collided with a troopship in fog with the loss of several hundred people.

He also wrote several books of biography, children's fiction and naval history, including When I Was in Patagonia (1953), and a play based on the Mary Celeste mystery.

Julian Huxley took the whole thing seriously, and was irritated to the point of peevishness by foolish answers, especially if they were propounded by the third member of the group, known as Commander Campbell.

Huxley and Joad were furious, but next week Commander Campbell said "I've had 200 letters from people whose heads steam when they eat marmalade".
