Lester Joseph Gillis (December 6, 1908– November 27, 1934)

Gillis, known by the alias George Nelson, better known as Baby Face
Nelson, was a notorious bank robber in the 1930s. Gillis was given the
nickname Baby Face due to his youthful appearance and small stature,
although few dared call him "Baby Face" to his face. Criminal associates
instead called him "Jimmy". Nelson entered into a partnership with John
Dillinger, helping him escape from prison during the famed Crown Point,
Indiana Jail escape, and was later labeled along with the remaining gang
members as public enemy number one.

Nelson was responsible for killing more FBI agents in the line of duty
(three: W. Carter Baum, Herman Hollis, and Samuel P. Cowley) than
any other person. Nelson was fatally shot by FBI agents during a
shootout called The Battle of Barrington.
