Eubie Blake said he was 100 years old but after he died researchers found his SSI application he made out in the late 30's and it revealed he was actually born in 1887 instead of 1883. I may be wrong about the 1887 date because I read that a long time ago and am going by memory but if it is not 1887 then it is 1886 or 1888. He was a few years younger than he said.
Also there were three men that claimed to be the last living Confederate veterans after the last real one died in 1954. The oldest and last was a man who died in 1959 claiming to be 117 years old making him born in 1842. It was discovered 20 years after he died that he was actually born in 1855. Then after that was found out they checked for information on two others and discovered they were frauds too.
So by a man making himself older than he actually is he can claim certain distinctions and honors.
