Larisa Latynina, who won 18 medals in the 1956, 1960 and 1964 Olympics while competing for the Soviet Union, was at the Aquatics Centre in London on Tuesday to watch Phelps, and she says she was happy for him.
"I saw him swim, and I saw my record swim away," she told The Associated Press in a telephone interview.
"He's very talented — no doubt about that," the 77-year-old Latynina added.
Latynina competed in an era when gymnastics was more about femininity and maturity, rather than teenage acrobatics, which has dominated the sport for decades.
It's not unusual for gymnasts today to retire at 18, while Latynina made her debut in international competition at the age of 19. She was four months pregnant with her daughter Tatyana while competing at the world championships in 1958.
Latynina won her last medal at the Tokyo Games in 1964 when she was nearly 30 — unusually old for gymnasts.
Three-time Olympic medallist Nadia Comaneci, described as the best female gymnast in history, retired in 1981 when she was 20.
"We knew about her because we are in the same sport, and you always pay attention to the history," Comaneci said in an interview. "We grew up watching — I didn't compete with her, but I watched her performances."
Latynina's fame peaked at a time when television in the Soviet Union was practically nonexistent. Although she is revered and respected by the gymnastics community at home and abroad, she is not as visible as Comaneci and younger gymnasts.
Comaneci said Latynina was determined "to be the best," although gymnastics was a very different sport in that era.
"They were actually ladies competing in gymnastics. And you look back at the equipment, it was different then," Comaneci said. "I don't want to say primitive, but that's what it was. The beam was wood, it was not very good for your heels."
Latynina came from a background in ballet, raised by a single mother amid World War II because her father was killed in the Battle of Stalingrad in 1943 when she was nine. She told state-owned Rossiya TV n 2010 that her mother swept floors, washed dishes and worked as a night guard to pay for her dance classes in her hometown of Kherson, on the Black Sea, while Ukraine was part of the Soviet Union. But Latynina had to give up ballet when her teacher left town, and she turned instead to gymnastics.
Because Latynina's success was so long ago, people outside the sport may have forgotten what she accomplished.
"This is the first time people worldwide are acknowledging her in such a wonderful way for what she's done," Comaneci said. "People tend to forget things. Eighteen medals — that's a lot."
Latynina said that she doesn't regret that her record was broken, because Phelps deserves it.
"He did a great job. As an athlete, I could only be happy to see that there is such a talented athlete who was able to break that record," she said.
Latynina still owns several records and is the only woman to have won nine Olympic gold medals.
Russian Sports Minister Vitaly Mutko told the news agency R-Sport that Latynina "will still remain one of the greatest athletes in history."
