Jerry Grandenetti studied art at the School of Visual Art and the Pratt Institute in New York, specializing in architectural drawing. In 1946, he was looking for a job at the various comic houses in New York, and he ended up as an assistant to Will Eisner on 'The Spirit'. He soon developed his talent, and started drawing 'The Secret Files of Dr. Drew' in Eisner's style for Ranger Comics. In the 1950s, he did the drawing on 'Crimebuster' and various western and war comics for DC Comics (a.o. 'Tomahawk', 'The Unexpected'). Between 1959 and 1972, he additionally worked on the 'Rip Tide' newspaper strip.

During the 1960s, Grandenetti developed a more "loose" style. He started working for Warren, creating stories such as 'In Close Pursuit', 'The Art of Horror', 'The Adventure of the German Student', 'Type Cast!', 'House of Fiends' and 'Bernice' for the black-and-white magazines Eerie and Creepy. He has become known as one of the best artists in the genre, and retired from comics to go into advertising art.
