In 1925, bookmaker and business tycoon Tim Mara founded the New York Football Giants for the sum of $500, making the team one of the original members of the newly founded National Football League. In 1929, in the midst of the Great Depression, Tim Mara passed the ownership over to his two sons, Wellington and Jack, as a means to protect the team during turbulent financial times. The two would run the team in tandem with their father, until Tim passed away in 1959 and Jack passed away in 1965.
In 1965, Jack’s son Tim took over his share of the ownership and he and Wellington would run the franchise until Tim sold his share of the team to Bob Tisch in 1990, due to the fact he was battling cancer.
