History
The Mighty Mite
Al Pratt was born in 1920. Pratt was a sophomore at Calvin College in 1940 and suffered indignity due to his short stature. This led to him being ever the target of harassment and bullying, and referred to as "Atom Al" by his tormentors, leading to him being unable to impress Mary James, the girl of his dreams. One day, feeling sympathetic he bought dinner for a vagrant who turned out to be Joe Morgan, a former boxing champ. Morgan promised Pratt he could be made into a muscular man with the right training. In under one year Pratt became a massively strong fighter, and he decided to use his new ability to protect the oppressed as the “mystery man” Atom.
World War II
At the start of World War II, President Roosevelt organized the "mystery men" to band together and create the Justice Society of America. Al was a founding member and later the All-Star Squadron where he struck up a strong friendship with fellow member Wildcat. He was present when the JSA battled Ian Karkull, in which Atom was bathed in mystical energy that kept him young for decades in the course of his battle with Karkull.
The Human Atomic Bomb
In another battle alongside the All-Star Squadron, Al Pratt fought the reluctant villain known as Cyclotron. Energy released in that battle caused Al Pratt to develop radiation immunity by the late-1940s. But when Al and Starman went to the Manhattan Project site to stop a rising foe, Atom, without thinking, ran out to the fallout area to save Starman and was caught in another explosion. He was unaffected by this, however their foe was defeated. Surviving the blast completely unharmed, it was discovered that the further radiation gave him more superpowers.
Career, Marriage, Life
Al was always very intelligent but ignorant towards nuclear physics; but after the incident with Starman at the Manhattan Project site, he then started studying nuclear physics and gained his PhD to become a brilliant scientist. Later he took up a job of a nuclear physics professor at Alma Mater Calvin Collage. In the early 50s, Atom retired along with the rest of the JSA after being urged by the American government to remove their masks and work for them. Al then revealed himself as The Atom to his sweetheart Mary James and her parents and then proposed to her. They married and had a happy life together.
Years later, Atom came out of retirement to rejoin the JSA. He and the rest of the JSA teamed up with the Justice League of America for the first time to battle a group known as the Crime Champions. During this adventure, Atom met Ray Palmer, the modern-day Atom. Al continued battling evil alongside the JSA and his best friend Wildcat. Atom's bravery inspired his godson Albert Rothstein, the grandson of Cyclotron (who looked up to Al as a father figure), to use his powers for good as the superhero known as Nuklon.

Tragedy
Al and his wife became pregnant and were expecting a son, but a great enemy of Al and the JSA deduced that the child would inherit the Atom's powers of a human atomic bomb and be a tool in his plot to dominate the world. When Mrs. Pratt gave birth, Savage stole the child and killed Mary Pratt. When Al discovered the news of her death, he was utterly devastated. After this tragedy he stayed close to his friends Wildcat, Jay Garrick and Alan Scott. Despite his reluctance to get back into crime fighting, Atom joined his teammates in battling a scheme concocted by their old foe, Ultra-Humanite. He stayed with the JSA when the group reassembled.
Death
Years later, Atom joined his fellow JSA members in taking part in the event known as Zero Hour. Most of the JSA went to the realm known as Vanishing Point where they were ambushed by the being known as Extant. Extant taunted his foes with boasts about how he could control time, and as usual, the hot headed Atom hurled himself at Extant. The time-controlling villain fired an energy blast and killed Atom instantly. He then proceeded to decimate the ranks of the JSA. Waverider rescued the heroes and took them and Al Pratt's body back to Earth. Al Pratt was buried in the superhero cemetery known as Valhalla.
Legacy
Blackest Night
Albert's body was later reanimated by Black Hand as a member of the Black Lantern. Like all Black Lanterns, he was sent out to kill the person who his death most affected, his son Grant, though he was stopped by Ray Palmer. After the crisis was over, Pratt’s corpse was returned to Valhalla.
Afterlife
In the afterlife, Al befriended David Knight. David brought his brother, the next Starman, Jack Knight to a banquet in limbo attended by Atom and several other deceased mystery men.
