Solomon Cutner, who lived from 1902 to 1988. He was a gifted pianist, whose career was cut short by a stroke. This paralysed his right arm, but in spite of that, he managed to finish a recording session on which little evidence of the stroke can be heard. The Wikipedia article links to an obituary in the New York Times, which states that the stroke occurred in 1965. Everywhere else the date is given as 1956. Transcription error? Don't think so. The NYT also states that the pianist recorded in the 1960s, which is not correct.
