London, May 29th 1917. Leopold de Rothschild died this morning at his home at Leighton Buzzard, after an illness of six weeks. Mr de Rothschild was 72 years old and was the third son of Baron Lionel de Rothschild, founder of the English branch of the famous banking house. For many years prior to the war Mr de Rothschild was a prominent figure in English horseracing circles and in 1904 his horse, St Amant, won the Derby.
Leopold de Rothschild was the younger of two surviving brothers of the late Lord Rothschild and had been considered the social member and sportsman of the family. He was a close friend of the late King Edward VII and his generosity made him popular everywhere. He was a leading member of the Jockey Club and was an authority on handicapping, of which he made a study. He was also the first President of Ealing Football Club (RU) in 1896 and remained in office until 1914.
In 1912 he had a narrow escape from assassination by a man known as William Tibbetts, who fired four shots at him as he was leaving his offices.
