John Nelson was the father of Prince
He died Saturday (August 25, 2001) at the age of 85 or 87 (I've seen conflicting reports).
Nelson was a jazz musician who began his career playing for the jazz group the Prince Rogers Trio in the 1950s. The band inspired his son's regal-sounding name.
While he was with the trio that he met Mattie Shaw, his eventual wife.
When Prince was a young boy, Nelson abandoned his family.
Prince's 1984 film Purple Rain, which featured a physically abusive father character based on Nelson, told the accounts of Nelson and Shaw's rocky abusive marriage.
During Prince's rise to fame in the mid-'80s, Nelson reconciled with his son and became one of Prince's writing partners, contributing to the tracks "Computer Blue," "The Ladder," "Christopher Tracy's Parade," and "Scandalous."
