This 1958 photo, A Great Day in Harlem by Art Kane, brings together 57 Jazz greats of the period. You can find their names on Google.
There is also a 1994 documentary by Jean Bach. The film shows how photographer Art Kane was able to get these night crawling cats & kitties together at 10:00 in the morning. It also answers the question, "Why did it take Monk so long to show up?"
