Sidney Ivan Davison Jr. (August 7, 1936 – May 5, 2014), known professionally as Dave Diamond, was an American radio DJ whose programs in the late 1960s and early 1970s helped popularise many psychedelic and acid rock bands.
He attended Howard Public High School, where he was known as Slide Davison and won medals and championships playing basketball, football and golf.
