This 1974 file picture shows Yves Saint Laurent. The legendary designer who reworked the rules of fashion by putting women into elegant pantsuits that came to define how modern women dressed, died Sunday evening, June 1, 2008, a longtime friend and associate said. He was 71.[Agencies]

When Saint Laurent announced his retirement in 2002 at age 65 and the closure of the Paris-based haute couture house he had founded 40 years earlier, it was mourned in the fashion world as the end of an era. His ready-to-wear label, Rive Gauche, which was sold to Gucci in 1999, still has boutiques around the world.

In October 2006, Saint Laurent slipped and fell outside a Paris restaurant during Fashion Week, suffering slight scratches but reminding fans of the perennially fragile designer's advancing age.

Saint Laurent was born Aug. 1, 1936, in Oran, Algeria, where his father worked as a shipping executive. He first emerged as a promising designer at the age of 17, winning first prize in a contest sponsored by the International Wool Secretariat for a cocktail dress design.

A year later in 1954, he enrolled at the Chambre Syndicale school of haute couture, but student life lasted only three months. He was introduced to Christian Dior, then regarded as the greatest creator of his day, and Dior was so impressed with Saint Laurent's talent that he hired him on the spot.

When Dior died suddenly in 1957, Saint Laurent was named head of the House of Dior at the age of 21. The next year, his first solo collection for Dior — the "trapeze" line — launched Saint Laurent's stardom. The trapeze dress — with its narrow shoulders and wide, swinging skirt — was a hit, and a breath of fresh air after years of constructed clothing, tight waists and girdles.

In 1960, Saint Laurent was drafted into military service — an experience that shattered the delicate designer, who by the end of the year was given a medical discharge for nervous depression.

Bouts of depression marked his career. Berge, the designer's longtime business partner and former romantic partner, was quoted as saying that Saint Laurent was born with a nervous breakdown.
