High Quality Content by WIKIPEDIA articles! Herman Edward "Ed" Hollis (January 1903 – November 27, 1934) was an American law enforcement official and Federal Bureau of Investigation (FBI) special agent. As an FBI special agent in the 1930s, Hollis worked with agents Melvin Purvis, Samuel P. Cowley and others fighting bank robbers, gangsters and organized crime in the Chicago area during the Great Depression. Hollis is best known for being killed in the line of duty during an intense shootout with Chicago-area bank robber Lester Gillis, a.k.a. Baby Face Nelson, at the Battle of Barrington in 1934. Hollis was also one of the three FBI special agents who shot John Dillinger near the Biograph Theater earlier that year, resulting in Dillinger`s death. One controversial account also implicates Hollis in the death of Pretty Boy Floyd. Hollis served as a special agent for the FBI`s field offices in Kansas City, Cincinnati, and Chicago for over seven years; at the time of his death, he was 31 years old.
