Katie Ledecky

Her Czech-born paternal grandfather Jaromír Ledecky arrived in New York City on September 8, 1947, as a student.

He later became an economist and married an Ashkenazi Jewish woman named Berta Ruth Greenwald in Brooklyn on December 30, 1956.

Through her paternal grandmother, Ledecky has relatives who were killed in the Holocaust in Europe.

Ledecky's mother is of Irish descent.

She was raised Catholic and continues to practice the faith, often praying the Hail Mary before her races.

Her uncle Jon Ledecky is a businessman and a co-owner of the NHL team New York Islanders.

Ledecky began swimming at the age of six due to the influence of her older brother, Michael, and her mother, who swam for the University of New Mexico.

In addition, she broke Janet Evans' American record of 8:16.22 that had stood since 1989.

Kathleen Genevieve Ledecky (born March 17, 1997) is an American competitive swimmer.

She has won seven Olympic gold medals and 21 world championship gold medals, the most in history for a female swimmer.

She has won a world record 16 individual gold medals at the World Aquatics Championships.

Ledecky's six individual gold medals at the Olympics and 26 overall medals at the World Aquatics Championships are records in women's swimming‌.

Ledecky is the world record holder in the women's 800- and 1500-meter freestyle (both long course and short course) as well as the former world record holder in the women's 400-meter freestyle (long course).

She also holds the fastest-ever times in the women's 500-, 1000-, and 1650-yard freestyle events.

She is widely regarded as the greatest female swimmer of all time and one of the greatest Olympians of all time.

In the final, Ledecky stunned the field, winning gold by more than four seconds, with a time of 8:14.63, the then second-fastest effort of all time just behind Rebecca Adlington's world record of 8:14.10 set in 2008.

In her international debut at the 2012 London Olympic Games as a 15-year-old, Ledecky unexpectedly won the gold medal in the women's 800-metre freestyle.

During the summer of 2012, she trained with the Nation's Capital Swim Club (formerly the Curl Burke Swim Club) under coach Yuri Suguiyama.

During the summers prior to 2012, she swam for Palisades Swim Team in Cabin John, Maryland.

Ledecky accepted an athletic scholarship to Stanford University, where she swam for coach Greg Meehan's Stanford Cardinal women's swimming team.

At the 2012 United States Olympic trials in Omaha, Nebraska (her first senior national competition), Ledecky made the Olympic team by placing first in the 800-meter freestyle with a time of 8:19.78, which was over two seconds ahead of second-place finisher Kate Ziegler.

In Omaha, Ledecky also placed third in the 400-meter freestyle (4:05.00) and ninth in the 200-meter freestyle (1:58.66).

Her third-place finish in the 400-meter freestyle was the fastest time ever swum by a 15- to 16-year-old American.

At 15 years, 4 months, and 10 days, she was the youngest American participant at the 2012 Olympic Games.

At the 2012 Summer Olympics in London, Ledecky qualified to swim in the final of the 800-meter freestyle by placing third overall in the heats with a time of 8:23.84.

In Bethesda, she attended Little Flower School through eighth grade and graduated from Stone Ridge School of the Sacred Heart in 2015.

During her high-school swimming career, Ledecky twice set the American and US Open record in the 500-yard freestyle, and she twice set the national high-school record in the 200-yard freestyle.

Ledecky finished her high-school career as the holder of the Stone Ridge school record in every swimming event except the 100-meter breaststroke.

Four years later, she left Rio de Janeiro as the most decorated female athlete of the 2016 Olympic Games, with four gold medals, one silver medal, and two world records.

Following Suguiyama's departure to coach for the University of California, Berkeley, she continued to train with the Nation's Capital Swim Club under coach Bruce Gemmell through the 2016 Olympics.

In December 2016, Ledecky was chosen as one of the sponsors of the US Navy aircraft carrier USS Enterprise (CVN-80) alongside Olympic gold medal-winning gymnast Simone Biles.

They are the first Olympians to be given this honor.

Ledecky was also named Associated Press Female Athlete of the Year in 2017 and 2022, international female Champion of Champions by L'Équipe in 2014 and 2017, United States Olympic Committee Female Athlete of the Year in 2013, 2016 and 2017, Sportswoman of the Year by the Women's Sports Foundation in 2017, and the ESPY Best Female Athlete in 2022.

Katie Ledecky was born in Washington, D.C. and raised in the suburb of Bethesda, Maryland, the daughter of Mary Gen (Hagan) and David Ledecky.

At the 2020 Olympic Games, Ledecky also emerged as the most decorated U.S. female athlete and became the first American female swimmer to win an individual event in three straight Olympiads.

In 2023, she won gold in the 800 meter World Championship, becoming the only swimmer - male or female - to win six World Championship gold medals in the same event.

In total, she has won 46 medals (36 golds, 9 silvers, and 1 bronze) in major international competitions, spanning the Summer Olympics, World Championships, and Pan Pacific Championships.

During her career, she has broken sixteen world records.

Ledecky's success has earned her Swimming World Female World Swimmer of the Year a record-breaking five times.

In December 2020, she completed the required courses for a Bachelor of Arts in psychology and minor in political science from Stanford University, and graduated in June 2021.
