Sir Alexander (Alec) Balmain Bruce Valentine OStJ MA (22 December 1899 – 1 December 1977),[1] was Chairman of the London Transport Executive from 1959 to 1963 and Chairman of the London Transport Board from 1963 to 1965.

[1] Valentine was educated at Highgate School and Worcester College, Oxford before working in the gas industry until 1927.

[1] In 1928, he moved to the Underground Group where he worked as assistant to its managing director Frank Pick.

[1] As part of the board, Valentine argued for the abandonment of Trams in London, seeing them as a major cause of road congestion, which would be relieved by the introduction of buses, with the aesthetic benefit of doing away with overhead wires and the noisy operation of trams.

[8] Valentine was a keen bird-watcher and walker, and, taking his pen-name from a British wild bird, he wrote articles on country walks as Fieldfare in the Evening News during the 1930s.
