Tom Dreesen, a pioneering stand-up comedian known for his role as one half of one of America’s first interracial comedy duos and for his long tenure as Frank Sinatra’s opening act, died Wednesday at his home in Los Angeles. He was 86. A cause of death was not disclosed.

Born on Sept. 11, 1939, in Chicago and raised in suburban Harvey as one of eight children, Dreesen served in the U.S. Navy before pursuing a career in entertainment. Following his military service, he worked various jobs, including selling insurance, before establishing himself in comedy.

In 1969, Dreesen teamed with actor and comedian Tim Reid, who is Black, to form the duo “Tim and Tom.” Emerging amid ongoing racial tensions, the pair used humor to bridge divides and promote understanding across audiences. They performed together until the mid-1970s, with Reid later gaining solo success as DJ Venus Flytrap on the television sitcom WKRP in Cincinnati, a show on which Dreesen also guest-starred.

After parting ways with Reid, Dreesen developed a solo career that included more than 500 national television appearances. He appeared on The Tonight Show Starring Johnny Carson 60 times and was a frequent guest and occasional guest host on The Late Show with David Letterman, where he forged a lasting friendship with Letterman through their early work at The Comedy Store in West Hollywood.

Dreesen’s final television appearance was in June 2026 on the show Comics Unleashed with Byron Allen, which took over the time slot of the canceled late-night show hosted by Stephen Colbert on CBS.

He was best known for his 14-year run as the opening act for Frank Sinatra, developing a close personal relationship with the singer. Reflecting on their bond, Dreesen once described Sinatra as a father figure who offered guidance and friendship.

Beyond Sinatra, Dreesen toured with other notable entertainers including Sammy Davis Jr., Liza Minnelli, Smokey Robinson, Gladys Knight, and Tony Orlando. Deana Martin, daughter of Dean Martin, honored Dreesen as one of the most brilliant comedians of all time, noting on social media that he would continue “opening for Dean, Frank and Sammy” in spirit.

In addition to his comedy career, Dreesen acted in television series such as Columbo, Murder, She Wrote, and Touched by an Angel. His film credits include Spaceballs, Man on the Moon, Trouble With the Curve, as well as HBO movies The Rat Pack and Lansky.

Dreesen also contributed as an author, co-writing the 2008 book Tim and Tom: An American Comedy Act in Black and White and publishing his memoir in 2020. His philanthropic efforts included motivational speaking and advocacy for veterans’ causes, serving as an ambassador for the Gary Sinise Foundation.

Tom Dreesen is survived by his daughters Amy and Jennifer from his marriage to Maryellen Subock, which ended in divorce in 1984, and seven grandchildren. His son Tommy preceded him in death. Tributes from peers and organizations recognized him as a talented comedian and a dedicated patriot.
