Baby Face Nelson: The Violent Criminal Who Killed More FBI Agents Than Any Other

History · Published 3 October 2026 Swipe more like this →

In short: Lester Joseph Gillis, known as Baby Face Nelson, was a diminutive bank robber who rose to become Public Enemy Number One. A key figure in the Depression-era crime wave, his short life ended in a brutal shootout that claimed his own life and those of two federal agents.

Born in Chicago in 1908, Lester Joseph Gillis began his criminal trajectory early, serving time in a reformatory after an accidental shooting at age twelve. By the early 1930s, he had transitioned from bootlegging to organized armed robbery. His nickname, 'Baby Face,' stemmed from his youthful appearance, though he was known to associates as 'Jimmy.' His violent reputation was cemented through a series of high-stakes heists and a willingness to engage in lethal gunfights, eventually leading to his association with the notorious John Dillinger.

The FBI's pursuit of Nelson intensified following the disastrous 1934 raid on Little Bohemia Lodge in Wisconsin. Despite the bureau's goal of capturing the gang, the operation resulted in the death of agent W. Carter Baum and the escape of the criminals. Nelson’s subsequent notoriety grew as he became the primary target for J. Edgar Hoover, who sought to restore the FBI's reputation after the public relations failure at the lodge. Nelson was eventually designated Public Enemy Number One following the deaths of John Dillinger and Pretty Boy Floyd.

The end came on November 27, 1934, in Barrington, Illinois. After a high-speed chase, Nelson engaged in a fierce gun battle with agents Herman 'Ed' Hollis and Samuel P. Cowley. Despite sustaining a fatal abdominal wound from a machine gun slug, Nelson continued to advance, ultimately killing both agents before fleeing the scene. He died later that evening, with his wife Helen Gillis by his side. His body was later discovered wrapped in a blanket, a final act of care from a wife who would herself serve time for harboring him.
