DETROIT -

Buffalo Bills founder and owner Ralph Wilson Jr. has died at the age of 95.

He was the longest tenured active NFL franchise owner. He lived in Grosse Pointe Shores and was born in Detroit in 1918.

Wilson was elected to the Pro Football Hall of Fame in 2009. He was one of the original founders of the American Football League.

Bills President Russ Brandon made the announcement at the league's winter meetings in Orlando on Tuesday. The cause of death has not been revealed, but Wilson had been in failing health for several years.

Under Wilson's ownership the Bills achieved two AFL championships -- 1964 and 1965 -- and four American Football Conference championships -- 1990, 1991, 1992 and 1993. They never won a Super Bowl and are the only NFL to go to the big game in four straight years.
