Bogart
1960s: from Bogart, Humphrey, who often smoked in films.
wiktionary
From actor Humphrey Bogart, from Dutch surname Bogart(“keeper of an orchard”), from boomgaard(“treegarden, orchard”), cognate to English boom(“piece of wood”)/ beam + garden.
Senses of selfishness and excess evolved from the original 1960s use meaning “keep a joint in the mouth instead of passing it on”, recalling the actor’s signature practice of keeping a cigarette dangling from his mouth even while speaking. Other senses of “bullying” or “tough guy” also originated in the 1960s and recall the actor’s various movie roles.
Another potential origin of the vernacular comes from Humphrey Bogart's role in the film The Treasure of the Sierra Madre (1948) in which his character, Dobbs, becomes increasingly selfish with the gold mine that he shares with his two partners.
