Gallagher was born in Bayonne, New Jersey. His father, a police officer, died when he was eight. He began working at a young age as a newsboy, and later a soda jerk.[2] He attended St. Mary's School and Bayonne High School and graduated from John Marshall College in 1946; in 1945 and 1946 he was a member of the faculty of Rutgers University. He also graduated from John Marshall Law School with an LL.B. in 1948 (both now part of Seton Hall University, and engaged in additional studies at New York University in 1948 and 1949. Gallagher was admitted to the bar in 1949.
As a congressman, Gallagher chaired the Invasion of Privacy Subcommittee.[4] Gallagher was a critic of the tactics of Federal Bureau of Investigation Director J. Edgar Hoover and Attorney General Robert F. Kennedy. Gallagher was approached by attorney Roy Cohn, who asked him on behalf of Hoover to hold hearings which would shift the blame for government surveillance from Hoover to Kennedy. Gallagher refused.[5]
Media accounts then surfaced, including Life magazine,[4] which contained alleged leaked material from FBI wiretaps suggesting that Gallagher was connected to the mafia, Gallagher accused Hoover of fabricating the stories to hound him from public life.[6][7] Cohn met with Gallagher again, demanding on Hoover's behalf that he resign or face further allegations.[5]
Gallagher was accused of evading payment of $74,000 in federal income taxes in 1966. He pled guilty in 1972 to tax evasion and perjury, sentenced to two years in prison and fined $10,000.[4][8]
A book detailing Gallagher's side of the story was published in 2003.[9]
