Sir John William Maxwell Aitken, 2nd Baronet, DSO, DFC (15 February 1910 – 30 April 1985[1]), briefly 2nd Baron Beaverbrook in 1964, was a Canadian-British fighter pilot and flying ace of the Second World War, a Conservative politician, and press baron. He was the son of Max Aitken, 1st Baron Beaverbrook.
In 1946, he entered the family newspaper business, as a director of the Express Group, and would become Chairman of Beaverbrook Newspapers Ltd. At the 1945 general election, Aitken was elected Member of Parliament for Holborn with a majority of 925.
Unfavourable boundary changes meant that the Labour Party took the successor seat in 1950 comfortably and Aitken did not stand at that or subsequent elections. He also served as Chancellor of the University of New Brunswick.
