From Michael Barrier:
Clyde Henry “Gerry” Geronimi was born in Chiavenna, a village north of Lake Como in the Italian Alps, on June 12, 1901. His family moved to New Rochelle, New York, in 1907 (according to Geronimi himself) or 1909 (according to the 1910 federal census). Not long after that, Geronimi’s given names, Clito Enrico, were Americanized to Clyde Henry. [...]
As I interviewed other members of the Disney staff during research for my book Hollywood Cartoons: American Animation in Its Golden Age, I grew used to hearing fierce criticism of almost all the directors (only Wilfred Jackson was largely immune), but the hostility to Geronimi was uniquely broad and comprehensive.[...]
Milt Gray and I interviewed Geronimi on November 5, 1976, in Newport Beach, at the very end of one of my hurried trips to California to record interviews with animation veterans for Hollywood Cartoons.[...]
