Li Ching Yuen

Li ChingYuen or Li ChingYun was a Chinese herbalist, martial artist and tactical advisor, known for his supposed extreme longevity. He claimed to be born in 1736, while disputed records suggest 1677. Both claimed lifespans of 197 and 256 years far exceed the longest confirmed lifespan of 122 years and 164 days of the French woman Jeanne Calment. His true date of birth was never determined and his claims have been dismissed by gerontologists as a myth.

Whereas Li ChingYuen himself claimed to have been born in 1736, Wu Chungchieh, a professor of the Chengdu University, asserted that Li was born in 1677 according to a 1930 New York Times article, Wu discovered Imperial Chinese government records from 1827 congratulating Li on his 150th birthday, and further documents later congratulating him on his 200th birthday in 1877. In 1928, a New York Times correspondent wrote that many of the old men in Lis neighborhood asserted that their grandfathers knew him when they were boys, and that he at that time was a grown man.
