Antony Charles Robert Armstrong-Jones, 1st Earl of Snowdon, (born 7 March 1930) is an English photographer and film maker. He was married to Princess Margaret, younger daughter of King George VI and younger sister of Queen Elizabeth II. He is known professionally, and credited, simply as Snowdon.
Armstrong-Jones was born the only son from the marriage of the barrister Ronald Armstrong-Jones(1899–1966) and his first wife, Anne Messel (1902–1992, later Countess of Rosse).
His maternal great-grandfather was the Punch cartoonist Linley Sambourne (1844–1910) and his great-great-uncle Alfred Messel was a well-known Berlin architect.
His parents separated when he was young and as a schoolboy he contracted polio. For the entire six months that he was in Liverpool Royal Infirmary recuperating, his only family visits were from his sister Susan.
Armstrong-Jones was educated at Eton and Cambridge, where he studied architecture. While at Cambridge, he coxed the winning Cambridge boat in the 1950 Boat Race. After university, he took up a career as a photographer in fashion, design and theatre. As his career as a portraitist began to flourish, he became known for his royal studies, among which were the official portraits of Queen Elizabeth II, and the Duke of Edinburgh for their 1957 tour of Canada.
