Michael Phelps was born on 30 June 1985 in Baltimore, Maryland, and began swimming at age seven — partly to follow his sisters, partly to channel energy that had been diagnosed as ADHD. He joined the North Baltimore Aquatic Club under coach Bob Bowman, set his first national age-group record at ten, and qualified for the Sydney Olympics at fifteen, the youngest American male Olympian in 68 years. He didn't medal in Sydney. He never missed the podium again.
What followed across four Games — Athens, Beijing, London, Rio — was the most decorated Olympic career in the history of sport: 28 medals, 23 of them gold, both records that may never be approached. The peak was Beijing 2008, where he won all eight events he entered and set seven world records, including the legendary 4×100m freestyle relay anchored by Jason Lezak. Over his career he set 39 individual and relay world records and won 33 World Championship titles. He retired after Rio at 31, the oldest individual swimming gold medallist in Olympic history.
Off the water, Phelps has been equally significant for his public advocacy around mental health, speaking openly about depression and therapy in ways that reshaped how athletes talk about psychological wellbeing. He lives in Scottsdale with his wife Nicole and their three sons.
