Who Is William Devane?
William Devane is an American character actor whose authoritative screen presence made him a natural choice for presidents, politicians, military men and powerful businessmen. He played President John F. Kennedy in the 1974 television film The Missiles of October, a performance that earned him an Emmy nomination and set the tone for a career built on gravitas rather than glamour.
He went on to a long run as the ruthless Greg Sumner on Knots Landing from 1983 to 1993, and later to the role of James Heller, the President and father of Jack Bauer’s love interest, on 24. He has also played presidents and senior officials in films such as Space Cowboys, Hollow Man and The Dark Knight Rises.
William Devane Early Life and Education
William Devane was born on September 5, 1939, in Albany, New York, to Joseph Devane, who worked as Franklin D. Roosevelt’s chauffeur when he was governor of New York, and Kate Devane. His ancestry is Irish on his father’s side and Dutch and German on his mother’s side, and he grew up in the Albany area.
He attended Philip Schuyler High School in Albany, then studied at the American Academy of Dramatic Arts in New York, graduating in 1962. He began his career in the theatre, appearing on Broadway and with the New York Shakespeare Festival, and he made his film debut in the 1967 film In the Country.
William Devane Acting Career
Devane built his screen career steadily through the 1970s, appearing in films such as McCabe & Mrs. Miller (1971), Marathon Man (1976) and Yanks (1979), and in television movies including The Missiles of October. His breakthrough television role came in 1983, when he joined the cast of Knots Landing as Greg Sumner, a role he played for ten years and 269 episodes.
After Knots Landing he continued to work constantly in film and television, including roles in Payback, Space Cowboys and Hollow Man, and in 2005 he joined 24 as James Heller, returning for the 2014 limited series 24: Live Another Day. He has also appeared in series including Stargate SG-1, The West Wing, Psych and Bosch, and in 2023 he was still acting, with a role in the film The Last Stop in Yuma County.
William Devane Net Worth in 2026
William Devane net worth in 2026 is estimated at $5 million, a figure that has remained stable in most reputable profiles for years. It reflects a long, working acting career rather than the blockbuster salaries of a modern film star, and it is consistent with the scale of his television and film work, his later commercial work and his property holdings.
Some lower quality sites inflate the figure to $25 million or more, but those claims have no credible sourcing and contradict the more careful profiles. For the most reliable single source, see the William Devane net worth page, which gives the $5 million estimate and the basic facts of his career.
| Published Claim | Status |
| $5 million (2026) | Most reliable estimate; Celebrity Net Worth, updated January 2026 |

| Exact salary or property value | Not publicly disclosed; do not treat guesses as facts |
William Devane Income Sources
Devane’s main income source has always been acting, with six decades of work in theatre, film and television. His long run on Knots Landing, his recurring role on 24 and his many film roles provided steady salaries, while residuals and repeat fees from those long running shows added to his earnings over time.
Since 2012 he has also earned money as a spokesman for Rosland Capital, a precious metals company, appearing in its television commercials. That commercial work, combined with his acting residuals and his property, forms the bulk of his later career income.
William Devane Real Estate and Business Ventures
Beyond acting, Devane has long had an interest in property and in the horse world. He owned a 10-acre equestrian property in California, which he sold in 2013 for $1.2 million, and he has lived for many years in a home near Palm Springs, California, where he keeps horses.
He also ventured into the restaurant business, opening Devane’s Italian Kitchen in Palm Desert, California, a restaurant he later sold. The venture showed a different side to the actor, but it was his acting and commercial work that provided his main income.

William Devane was married to Eugenie McCabe Devane for more than six decades, with sources giving their wedding year as 1961 or 1962. The couple had two sons, Joshua and Bill, and Eugenie died in 2022.
Devane has kept his private life largely out of the press, and he has spoken in interviews about his love of horses and of life in the California desert. His son Bill died in an accident, a loss Devane has rarely discussed in public.
Final Thoughts
William Devane net worth in 2026 is best estimated at $5 million, a figure that fits a long, steady acting career rather than a fortune built on blockbuster paydays. The higher figures found on some sites have no credible backing and should be ignored.
What is certain is the career behind the number. Six decades on stage and screen, a decade on Knots Landing, a memorable run on 24 and a second career as a commercial spokesman have given Devane a secure, if modest by Hollywood standards, fortune.
