Sir Alfred Lane Beit, 2nd Baronet (January 19, 1903 – 12 May 1994) was a British Conservative Party politician, art collector and philanthropist and honorary Irish citizen.
His uncle was Alfred Beit, a South African mining millionaire, after whom he was named when he was born in London on 19 January 1903. His father Otto Beit (1865–1930) was awarded the KCMG in 1920 and was created a baronet in February 1924. His mother was Lilian, daughter of Thomas Lane Carter of New Orleans, US. On Sir Otto's death in 1930, Alfred inherited a large fortune as well as numerous works of art, including works by Goya, Vermeer, Rubens and Gainsborough. Having lived at 49 Belgrave Square, he bought a mansion on Kensington Palace Gardens (the most exclusive address in London), where these paintings were put on display.
Beyond personal wealth, by 1930 the Beit family had philanthropically supported primarily the Imperial College of Science and Technology, the Rhodes Trust and had established the Beit Memorial Fellowship for Medical Research, besides many smaller donations to other groups.
Known from 1930 as Sir Alfred Beit, he was elected Conservative Member of Parliament (MP) for St Pancras South East at the 1931 general election and re-elected in the 1935 general election. When the Second World War started he joined the Royal Air Force serving in Bomber Command. In 1944 he was appointed PPS to Oliver Stanley, the Colonial Secretary.
