The Right Honourable Robert Anthony Eden, 1st Earl of Avon, KG, MC, PC (June 12, 1897 January 14, 1977), British politician, was Foreign Secretary during World War II and Prime Minister of the United Kingdom during the 1950s. He is remembered mainly for his role in the disastrous Suez Crisis of 1956. In a 2004 poll of 139 political science academics organised by MORI, Eden was voted the least successful British Prime Minister of the 20th Century. This echoed the outcome of an earlier survey by BBC Radio's The Westminster Hour, ranking the British Prime Ministers of the 20th Century. Winston Churchill came top, Eden bottom.
