Margaux Louise Hemingway was born in Portland, Oregon, February 16, 1955, and was the older sister of actress Mariel Hemingway and the granddaughter of writer Ernest Hemingway. Hemingway was named for the wine, Château Margaux, which her parents, Puck and Jack Hemingway (eldest son of Ernest), were drinking the night she was conceived. In addition to Mariel, she had another sister, Joan. She grew up on her grandfather’s farm in Ketchum, Idaho.
At six feet tall, Hemingway experienced success as a model, including a million-dollar contract for Fabergé as the spokesmodel for Babe perfume in the 1970s. Her lucrative contract with Fabergé was the first million dollar contract ever awarded to a fashion model. She also appeared on the covers of Vogue, Elle, Cosmopolitan, Harper’s Bazaar, and appeared on the June 16, 1975 cover of Time dubbed as one of the “new beauties”. The September 1, 1975 cover issue of American Vogue christened Hemingway as “New York’s New Supermodel.”
In an E! True Hollywood Story that profiled Hemingway’s life, her mentor and close friend Zachary Selig discussed how he helped launch Hemingway’s early career with his initial marketing and public relations work as she became a global celebrity.
