An heir to the Johnson & Johnson fortune, Robert Wood Johnson IV is the fat checkbook behind the New York Jets.

The great-grandson of Robert Wood Johnson I, who co-founded the pharmaceuticals behemoth Johnson &a Johnson, Woody was still in high school when his grandfather fired his father. But young Woody decided against going into the family business; instead, he took his share of the family fortune and settled in Florida, investing in cable businesses and real estate deals in the 1970s. His years down south weren't without controversy: A series of messy lawsuits unfolded and he endured an acrimonious split with his business partner. Johnson moved to New York in 1984, shortly after marrying his first wife, and set up a firm to manage his fortune as well as handle investments for other members of the Johnson family. He became increasingly active in philanthropy in the '90s, and moved into the sports business in 2000 when he purchased the Jets for $635 million from the estate of long-time owner Leon Hess.

After buying the Jets, Johnson announced plans to move the team into a proposed West Side Stadium that was to be built in Manhattan. After the project's defeat in 2005, however, Johnson decided to move the team into Metlife Stadium, a space the Jets share with the New York Giants. The cost of the entire project, split between the two teams, reached $1.6 billion, making it the most expensive stadium ever constructed.

With his ex-wife, Sale Johnson, Woody had three daughters: Daisy, Jaime and Casey. In 2009, Johnson married Suzanne Ircha Johnson, with whom he has two sons: Robert Wood Johnson V and Jack Wood Johnson. In late 2009, Johnson's daughter and tabloid-fixture, Casey, died of diabetic ketoacidosis. [Image via Getty]
