Michael Tell was a concert promoter and newspaper publisher who married actress Patty Duke briefly in 1970 and was the biological father of actor Sean Astin. Their marriage lasted 13 days; Sean’s paternity was established through DNA testing years later. Tell died in April 2025, aged 80. Beyond his Hollywood connections, he spent decades publishing the Las Vegas Israelite, a newspaper serving Southern Nevada’s Jewish community.
His life connects two distinct stories: the much-discussed family history surrounding Duke and her son, and a working career in live entertainment and local journalism. His own interviews offer a view of the latter, from organising performances as a teenager to taking responsibility for his family’s newspaper.

Michael Tell and Patty Duke’s brief marriage
Tell and Duke married in Las Vegas on June 24, 1970. A wedding photograph reproduced by the Las Vegas Review-Journal places the ceremony at the Little Church of the West. Their marriage lasted less than two weeks and ultimately ended in annulment.
Duke gave birth to Sean in 1971 and married actor John Astin the following year. John subsequently adopted Sean. That distinction explains why John and Tell both feature in accounts of Sean’s parentage: one was his adoptive father, the other his biological father.
How Sean Astin learned who his biological father was
Sean grew up believing John was his biological father. As a teenager, he was told that his father was Desi Arnaz Jr. Later, a relative of Tell’s suggested another possibility, leading Sean to undergo DNA testing.
As PEOPLE’s account of Sean’s paternity discovery explains, the result identified Tell as his biological father. Sean described the distinction himself in 2001: “John Astin is my father, Michael Tell is my biological father.” He also said he had a good relationship with Tell.
A career in concert promotion
Tell’s entertainment career began long before that family connection became public.
In his oral-history interview preserved by UNLV University Libraries, he recalled opening a teenage nightclub called the Twin Lakes Twist in Las Vegas in 1961. He described approaching Bobby Darin to perform and said Darin also helped bring Wayne Newton to the venue.
Tell later moved his concert business to Los Angeles. His recollections describe the practical work behind the performances: creating radio advertisements, promoting shows and booking entertainers. These were his own activities in the music business, separate from Duke’s acting career and Sean’s subsequent screen work.
Taking over the Las Vegas Israelite
Newspaper publishing was already part of the Tell family’s history. His parents, Jack and Beatrice Tell, founded the Las Vegas Israelite in 1965. After Jack died in 1979, Michael took over as co-publisher.
Tell recalled returning to Las Vegas to help his mother with the publication. He initially worked on circulation—getting copies into readers’ hands—before moving into publishing and editorial content.
He also described how the paper’s coverage evolved. As the local Jewish community expanded, the publication placed more emphasis on local stories alongside national and international Jewish news. His interview records a publisher concerned with distribution, community events and the everyday demands of sustaining a newspaper.
The publication’s own history credits him with continuing the newspaper for 40 years. It now identifies Bonnie Tell Lally and Michele Tell as the next generation carrying on the family’s publishing work.
His death in 2025
Michael Tell died on April 6, 2025, aged 80. The Las Vegas Review-Journal’s obituary, published on April 9, reported his death and recognised both his concert-promotion career and his newspaper work.
Las Vegas Mayor Shelley Berkley credited him with keeping the Israelite operating for decades and providing news that mattered to its readers. That contribution gives his biography a substantial chapter beyond his brief marriage: a long career maintaining a publication for the community he served.
