Originally from Cleveland, Ohio, Slam loved to fight and was typically portrayed in the middle of a brawl. His career was originally as a tough private detective. Slam often went undercover as a teacher, a magician, a prizefighter and even a singer on the radio. His partner was an aggravating, buffoonish man named Shorty Morgan. Slam was not too original. He started out as a slightly exaggerated version of Race Williams and other hard-boiled pulp detectives. Slam had many notable characteristics. He was the first private eye to appear regularly in comic books and he resembled Superman in his features, while being tall, muscular, raven-haired and square-jawed. Given his roots, that should not come as a surprise.
Currently Slam is a private detective, in his late 50's, operating in Gotham City. He has one son working in the GCPD, Sam Bradley Jr. Slam was once a cop working for the GCPD, but quit after watching years of corruption. He decided to open up his own detective agency because he still wanted to help, but not within the confines of the corrupted police force.
In 2001 he was brought back to Gotham PD after a long hiatus to investigate the death of the Catwoman and is also the Grandfather of Helena Kyle, Catwoman's daughter.
