Hennigan attended LSU on a trackscholarship but wanted to play football. He therefore transferred to Northwestern State University (then Northwestern State College) in Natchitoches, Louisiana, where he became the star of the team. In 1960, he joined the American Football League's Houston Oilers in the team's first year of operation. Prior to joining the Oilers, he had taught high school biology at a salary of some $2,700 per year. He kept his teacher pay stub in his helmet to remind him that he must succeed in pro athletics.
Hennigan scored the first touchdown in Oilers history, catching a 43-yard touchdown pass from George Blanda in the first quarter against the Oakland Raiders. That year, he caught 44 passes for 722 yards, averaging 16.4 yard per catch. He had six touchdowns. In the 1960 American Football League Championship Game, he caught four passes for 71 yards as the Oilers prevailed 24–16 to win the inaugural AFL title over the Los Angeles Chargers. After a promising rookie season, in 1961, he started all 14 games and established himself as a superstar in the AFL by setting a single-season record with 1,746 yards receiving along with 12 touchdowns. His record stood for 34 years until it was surpassed by both Jerry Rice and Isaac Bruce in 1995. In October alone, he had 822 receiving yards, the most in a single calendar month. One of quarterback George Blanda’s main targets, Hennigan was the second professional football player to catch more than a hundred passes in a single season (101 in 1964, an AFL record) and to twice gain over 1,500 yards receiving (1961 and 1964). He holds the all-time records for most games in a season with over 200 yards receiving with three, and most games in a season with over 100 yards receiving with 11. Hennigan had the All-time AFL single game record of 272 yards receiving, against the Boston Patriots on October 13, 1961. The 13 passes caught in the game is tied for the most ever in the AFL, shared with Lance Alworth, Lionel Taylor, and Sid Blanks. In the 1961 American Football League Championship Game, he had five catches for 43 yards as the Oilers prevailed for their second and final AFL title.
On January 19, 1962, Minden observed "Charlie Hennigan" Day. Then State SenatorHarold Montgomery, State Representative, Parey Branton, Mayor Frank T. Norman, and other local officials presented Hennigan with a signed document of his accomplishments. A luncheon and evening meal were served in his honor.[2] The event was postponed because of hazardous weather the previous week.[3] That year, he had 54 catches for 867 yards with eight touchdowns. In the AFL title game, he had three catches for 37 yards, but the Oilers lost in double overtime to the Dallas Texans.
Most 100+ yard receiving games (season): 10 (1961)

Hennigan had seven children, the oldest being Charles Jr., who was born in Natchitoches in 1957.
On April 6, 2002, Hennigan, then a Democrat but a registered Independent as of 2014,[8] ran in a special election for Place 8 on the Caddo Parish Commission, his parish's governing body. He was defeated by Republican Michael Long, 2,139 votes (74.9 percent) to 716 ballots (25.1 percent).
On December 20, 2017, Hennigan died at the age of 82.[9]
