Catherine Lacoste Biography:
Lacoste never turned pro, and played only a handful of big tournaments. But she won three of the biggest: the U.S. Women's Open, the U.S. Women's Amateur, and the British Ladies Amateur. Then she practically gave up the game.
Lacoste was the daughter of French tennis legend Rene Lacoste, who also founded the apparel company that carries the family name. Her mother, Simone de la Chaume, won the 1927 British Ladies Amateur - the tournament Catherine would also win 42 years later.
Catherine took up golf at Chantaco Golf Club - founded by her parents - in Saint-Jean-de-Luz, France, and quickly dominated the junior circuit in her region.
She developed a powerful game - Golf Digest many years later called her "arguably the most powerful player of her era."
As a 19-year-old in 1964, Lacoste led the French to victory in the World Amateur Golf Team Championships. She was supposed to play in the European Team Championships in 1967, but decided to skip the event to play the U.S. Women's Open.
Good choice. Lacoste took a 5-stroke lead into the final round, then held on for the victory despite bogeying five straight holes on the back nine of the final round. At the 17th hole, her competitors had to play a long par-5 needing three shots to reach the green. Lacoste pounded a 3-wood over trees to cut the corner of a dogleg, hit the green in two and birdied, sealing the victory.
She remains the only amateur to win the U.S. Women's Open. She was also the first European winner of that tournament and, at the time, the youngest.
In 1969, Lacoste scored an impressive double by winning both the U.S. Women's Amateur and British Ladies Amateur.
Then, having won all the tournaments she had set out to win, she essentially gave up the game. Lacoste continued playing for the French in the World Amateur Golf Team Championship in 1970, 1974, 1976 and 1978, but never again played in a top-level individual event.
Instead, she pursued family life, having four children, and business interests. She was president of Chantaco Golf Club for 30 years and still serves on the board of directors of Lacoste, the company her father founded.
