Michael Tell: Patty Duke’s Ex-Husband, Sean Astin’s Father and a Las Vegas Publisher
Michael Tell (1944 or 1945 to 2025) was a Las Vegas rock-concert promoter turned newspaper publisher, best known to the wider public as Patty Duke’s husband for 13 days in 1970 and as the biological father of actor Sean Astin. He ran the Las Vegas Israelite for decades, and his obituary in the Las Vegas Review-Journal portrays a man whose life was far larger than a single footnote in a Hollywood family story.
Online, though, Tell is usually reduced to that footnote. This article does two things. It lays out the paternity story, which has a surprising number of versions, in the order the evidence supports. And it restores the rest of his life, which the celebrity pages tend to skip.

Who Michael Tell Was
A Newspaper Family
According to the Las Vegas Review-Journal obituary, Tell was the youngest of three sons of Jack and Beatrice Tell and grew up in New York City. His father had been a photo editor at The New York Times, later bought a newspaper in northern Nevada, and moved the family to Las Vegas, where he launched the Las Vegas Israelite in 1964.
From Teen Nightclub to Rock Promoter
Before he took over the family paper, Tell worked in entertainment. The obituary says he started a nightclub for teenagers and booked performers such as Bobby Darin and Wayne Newton. Between 1968 and 1972 he brought rock acts to Las Vegas that rarely played there, among them Led Zeppelin, Black Sabbath, the Steve Miller Band and The Doors. That work earned him a place in the local Rock and Roll Hall of Fame.
He later relocated to Southern California. By his own account, he became the fifth-largest concert promoter in the United States and helped launch careers such as Jimi Hendrix’s and José Feliciano’s. Those are his claims as relayed in the obituary, not independently verified facts, so they are best read as the way he described his own career.
The Las Vegas Israelite
When his father died in 1979, Michael Tell took over the Israelite, a Jewish-community newspaper, and served as its editor and publisher until shortly before his own death. The obituary notes that he steered the paper away from heavy national coverage of Israel and toward local community reporting. In a city better known for casinos than for its civic institutions, that made the paper a record of local Jewish life.
Tributes quoted in the obituary reflect how he was seen at home. Las Vegas Mayor Shelley Berkley, who knew him for some 60 years, said his death marked the end of an era, and one of his nieces remembered him as an easygoing, relaxed relative.
The 13-Day Marriage to Patty Duke
Tell’s place in entertainment history stems from his marriage to Patty Duke in 1970. CBS News states that Duke was married to him for 13 days that year. Wikipedia’s entry on Duke, which lists a wedding date of June 26, 1970 and an annulment on July 9, 1970, matches that length. People’s account says instead that the marriage was annulled a year later, which probably reflects the timing of the legal paperwork and not the length of the marriage itself.
According to People’s account of Sean Astin’s story, Tell had been subletting Duke’s apartment when they married. The reasons for the wedding were tangled up with a tabloid-heavy moment in Duke’s life, and I found no first-hand account from Tell explaining them, so this article does not guess.
Sean Astin’s Parentage: Four Fathers, One Answer
Why There Is More Than One Version
Sean Astin was born on February 25, 1971, shortly after the brief marriage ended. His mother, Patty Duke, was involved at the time with more than one man, and each of them was publicly named at some point as his father: Tell, Desi Arnaz Jr. and John Astin.
The timeline, pieced together from People, CBS and Wikipedia, runs like this:
- Duke married John Astin in 1972, and he later adopted Sean.
- Duke’s 1987 memoir described Astin as the biological father, according to CBS, though she later said she had always believed it was Arnaz.
- When Sean was around 14, she revealed that Arnaz was his biological father, and the two went on to develop a relationship.
- Years later, a relative of Tell’s suggested the two might be related. Sean took a paternity test involving all three men, and it identified Tell as his biological father.
When Did He Find Out?
Sources disagree on how old Sean was. CBS and the Wikipedia article on Sean Astin place the test in 1994, when he would have been 23. The Review-Journal obituary says he learned at 25, and People’s account says he was nearly 26.The available sources do not align, so the most reliable conclusion is that the result came in the mid-1990s.
How the Family Responded
People reports that Duke publicly rejected the result in 2001. Sean, in the same coverage, said that John Astin is his father in every day-to-day sense, that Tell is his biological father, and that he had a good relationship with Tell. He also described Arnaz as something like a godfather. John Astin said the bond he had with Sean mattered more than a genetic one, and that he had become friendly with Tell.
Years later, Sean Astin has summed it up as having “four dads,” a phrase reported by ABC News and repeated in Wikipedia, a count that includes John Astin, Arnaz, Tell and a fourth man he calls Papa Mike. Tell’s obituary describes the relationship as warm: it says the two got along well and lists three granddaughters through Sean.
Marriage and Family Later in Life
Tell’s obituary names his wife, Nelcy Tell, as one of his survivors, along with a brother and several nieces. His other brother and both parents had passed away before him. The paper reports that a memorial service was scheduled at a Las Vegas mortuary and that the family asked for donations to a local temple in place of flowers.
Little else about his private life has been reported by reliable outlets. I found no interviews in which he discussed the 1970 marriage at length, and no verified accounts of other earlier relationships.
Why His Story Gets Distorted Online
Search results for his name are crowded with low-quality pages that I could not tie to any reliable source, and several of them focus entirely on the paternity story. Two cautions follow from the reporting above:
- The paternity story is not simply settled by Duke’s own words. She disputed the test, and the sources disagree on the date and on Sean’s age.
- His birth date and place of death are not confirmed in the obituary I could read, which says only that he was 80.
A reader looking for the truth is better served by the contemporary reporting: People on the paternity, CBS and Wikipedia on the marriage dates, and the Review-Journal on his career and survivors.
