Jack Keller was born on June 16, 1922 and grew up in Pennsylvania. The year after graduating from high school, this self-taught artist broke into com-
ics, working at the famous Quality Comics Group in 1941 and doing backgrounds for cartoonist Will Eisner's legendary Spirit newspaper comic. By 1950, he was working regularly at Atlas Comics drawing horror, cowboy and crime stories. There he started on one of his most well-known series, Kid Colt, Outlaw, from 1953 through the mid-60s.

By 1955, he began work for Charlton Comics, freelancing on such titles as Billy the Kid, Battlefield Action, Cheyenne Kid, Fightin' Air Force, Fightin' Army, Fightin' Marines and Submarine Attack. By 1957, Atlas Comics was virtually dead before it was reborn as Marvel Comics, so Keller began working at a car dealership while still drawing for Charlton. Keller applied his love of automotives to writing and drawing titles for them, comprising Drag 'n' Wheels, Grand Prix, Teenage Hotrodders, Surf 'n' Wheels, World of Wheels and most importantly, Hot Rods and Racing Cars. After ending his association with Marvel in 1967, he also did stories for DC Comics from 1968 to 1971, including Hot Wheels, based on the popular toy cars from Mattel. His artwork is notable for his attention to detail and intense drama, sometimes reminiscent of many of his contemporaries, like Jack Kirby, John Romita and Joe Kubert.

After retiring from comics, he still engaged in his love of cars by selling autos at Marshall Chevrolet in Reading, Pennsylvania and as a salesman at Fun Stuff Hobbies and Kiddie Kar Kollectibles. Jack passed away at St. Joe's Hospital in Reading at age 80, on January 2, 2003 and is buried at Forest Hills cemetery in Reiffton, Pennsylvania.
