Who Was Michael Tell?
Michael Tell was an entertainment promoter and longtime newspaper publisher.
His name became familiar to Hollywood audiences because of his brief marriage to Patty Duke.
However, his professional career started before he met her.
As a young businessman, he organized music performances in Las Vegas.
He worked with well-known musicians and helped introduce major rock acts to the city.
He later managed the Las Vegas Israelite, a community newspaper founded by his father.
Michael spent more than four decades helping the publication survive.

Michael Tell’s Early Life and Childhood
Michael Tell was born on March 1, 1945.
He grew up in New York City.
His parents were Jack Tell and Beatrice Tell.

His Father Jack Tell
Jack Tell worked in the newspaper industry.
He was associated with The New York Times, where he worked in photography and publicity.
Jack wanted to establish his own publication.
This ambition eventually brought the family to Nevada.
Michael accompanied his father during the move.
The experience helped introduce him to business and journalism.
His Mother Beatrice Tell
Michael’s mother was Beatrice Tell, whose maiden name was Goldstein.
She contributed to the family’s newspaper business.
After moving to Nevada, Beatrice helped with advertising and other responsibilities.
Michael later returned to Las Vegas partly because he wanted to support his mother after his father’s death.
Family responsibility became an important theme in his professional story.
Michael Tell Moved to Nevada as a Teenager
Michael was approximately 16 years old when he traveled west with his father.
Jack Tell hoped to acquire a newspaper in Nevada.
The publication was called the Territorial Enterprise.
It had historical connections with the state’s journalism industry.
Living in Virginia City
Michael and his father spent time in Virginia City.
The experience was different from growing up in New York.
Virginia City had a long history connected with mining and the American West.
However, the family’s newspaper venture did not succeed as planned.
They eventually moved to Las Vegas.
Settling in Las Vegas
Las Vegas was much smaller during the early 1960s than it is today.
Michael later recalled that the population was approximately 90,000.
His father found work in the local newspaper industry.
He worked at the Las Vegas Sun and later the Henderson Home News.
Meanwhile, Michael began developing his own business interests.
One of those interests was music.
Michael Tell Started a Nightclub as a Teenager
Michael’s entertainment career began surprisingly early.
In 1961, he established a teenage nightclub called Twin Lakes Twist.
The venue offered young people a place to enjoy music.
At the time, Las Vegas was already famous for casinos and adult entertainment.
However, there were fewer entertainment opportunities specifically for teenagers.
Michael saw a business opportunity.
Bringing Bobby Darin to the Club
In a 2018 oral-history interview with the University of Nevada, Las Vegas, Michael described approaching singer Bobby Darin.
He explained that he did not have enough money to pay the performer.
However, he wanted to create entertainment for local teenagers.
According to Michael’s recollection, Darin agreed to perform without payment.
The experience became an important turning point.
Booking Wayne Newton
Michael also recalled that Bobby Darin helped him arrange a performance by Wayne Newton.
The successful concerts attracted attention.
Michael later said that his first weekend in the entertainment business generated approximately $10,000 in profit.
For a teenager in the early 1960s, that was a substantial amount.
The experience convinced him that concert promotion could become a serious career.
Michael Tell Became a Rock Concert Promoter

The concert took place at the old Las Vegas Ice Palace.

The unusual arrangement became part of the city’s concert history.
Other Major Performances
Michael also helped arrange appearances by Led Zeppelin, Black Sabbath, and other popular acts.

Although Las Vegas later became famous for enormous concerts and music residencies, its earlier rock scene was much smaller.
Michael was among the promoters who helped it grow.

Michael attended Nevada Southern University.
The institution later became known as the University of Nevada, Las Vegas.
However, he did not complete a widely documented university degree.

Their personal connection began under unusual circumstances.
Michael Was Renting Patty Duke’s Apartment
According to accounts of their relationship, Michael had been subletting Duke’s apartment.
They knew each other only briefly.
Duke was experiencing a difficult period in her personal life.
Her relationships had attracted considerable public attention.
She was also uncertain about her pregnancy.
A Sudden Decision to Marry

The couple separated because their relationship had developed under complicated circumstances.
They had not known each other for very long.
The marriage was an impulsive decision rather than the result of a lengthy courtship.
The Marriage Was Annulled

In this case, the couple’s marriage ended after fewer than two weeks.
Duke later discussed the event in her memoir.
However, she and Michael did not maintain a widely documented long-term romantic relationship afterward.
Their Story Continued Years Later
Although their marriage ended quickly, their names became connected again.
The reason was Sean Astin.
For many years, uncertainty surrounded the identity of Sean’s biological father.
DNA testing eventually identified Michael.
That discovery changed the public understanding of the brief marriage.

John Astin Raised Sean
Patty Duke married actor John Astin in 1972.

Sean developed a close relationship with John.
Even after DNA testing revealed his biological connection with Michael, Sean continued considering John an important father figure.
How Sean Astin Discovered His Biological Father
Sean Astin’s understanding of his family history changed several times.
During childhood, he believed John Astin was his biological father.
Later, Patty Duke told him that Desi Arnaz Jr. was his father.
Sean developed a relationship with Arnaz.
However, the question was not finally resolved.
The DNA Test
During the 1990s, Sean underwent DNA testing to determine his biological parentage.
The results established that Michael Tell was his father.
The discovery attracted entertainment coverage.
However, Sean approached the situation with considerable maturity.
Sean Accepted His Family History
Sean later explained that he valued the different father figures in his life.
He recognized John Astin as the man who raised him.
