Yves Saint Laurent, one of the most influential fashion designers of the 20th century, died of a brain tumor yesterday at his home in Paris. He was 71.

Getting his start in the business at the mere age of 18 when Christian Dior hired him, he was named head designer of that house three years later when Dior died unexpectedly in 1957.

He launched his eponymous couture line in 1962, followed by his ready-to-wear collection Rive Gauche, and soon made fashion history with his signature “le smoking” tuxedo jackets, sleek pantsuits and beatnik looks.

Saint Laurent officially retired in 2002 and Gucci Group acquired Rive Gauche in 1999.
