Felix Cassel

Sir Felix Maximilian Schoenbrunn Cassel, 1st Baronet, PC, QC (16 September 1869 – 22 February 1953) was a British barrister who served as Judge Advocate-General from 1915 to 1934.

Cassel was born of an Anglo-German family in Cologne, Germany. He was educated at Elstree School, Harrow School and Corpus Christi College, Oxford. He was called to the Bar at Lincoln's Inn in 1894 and took silk in 1906. In 1910 he was elected to House of Commons as Conservative member for St Pancras West, a seat he held until 1916.

In 1914, he was commissioned into the London Regiment of the British Army and served in France until 1915, when he was recalled to London to assist the Judge Advocate-General. In October 1915 he was appointed Judge Advocate-General himself, despite opposition from some MPs, who were worried about his German origins.

Cassel was created a baronet in the 1920 New Year Honours. In 1937, he was appointed to the Privy Council, entitling him to the style "The Right Honourable".

He was succeeded in the baronetcy by his son Francis.
