Blake continued to play and record until shortly before what everyone thought was his 100th birthday. He uttered the memorable quote, "If I'd known I was going to live this long, I would have taken better care of myself."
Recent research by Peter Hanley in 2003, however, suggests that this was an exaggeration. His birthday is recorded in the 1900 US Census as 'February 1887', and when he had applied for a social security number in 1937, had given his date of birth as 7th February 1887. Hanley himself concluded 'In the final analysis, however, the fact that he was only ninety-six years of age and not one hundred when he died cannot detract, in any way, from his extraordinary achievements. He will always remain among the finest popular composers and songwriters of his era.'
Blake's authorized biography, Eubie Blake, was written by Al Rose.
