Mickey Hargitay: Biography, Career, and Fatherhood

You probably know him best as the father of Law & Order: SVU star Mariska Hargitay. But Mickey Hargitay was a lot more than a famous dad. He was a Hungarian immigrant who won Mr. Universe, married one of Hollywood’s biggest sex symbols, and then stepped into an entirely different spotlight—one that, decades later, would carry a surprising twist about his role as a father.

Born: January 6, 1926 · Died: September 14, 2006 · Nationality: Hungarian-American · Profession: Actor and bodybuilder · Spouse: Jayne Mansfield (1958–1964) · Children: 3 (including Mariska Hargitay)

Seven key facts about Mickey Hargitay, one pattern: a life lived in phases—immigrant, athlete, Hollywood husband, father, and ultimately a man whose family story held one last secret.

Is Mickey Hargitay the biological father of Mariska Hargitay?

Mariska Hargitay’s public revelation

• In 2025, Mariska Hargitay confirmed that Mickey Hargitay is not her biological father. She stated that the biological father is singer-comedian Nelson Sardelli (Encyclopaedia Britannica (reference work)).
• Mariska said she believed Mickey was her biological father until she was 25 years old (Wikipedia (online encyclopedia)). According to the same source, when she asked Mickey about her paternity, he denied that Sardelli was her father.

Who is Mariska’s biological father?

• Mariska Hargitay has identified Nelson Sardelli as her biological father. Sardelli, a singer and comedian, was romantically involved with Jayne Mansfield during her marriage to Mickey Hargitay (Encyclopaedia Britannica).
• The public confirmation came decades after Jayne Mansfield’s death, adding a new chapter to the family history.

The implication: Mickey Hargitay’s role as a father was no less real for the absence of a biological link. He was the man who was there—through the divorce, through Jayne’s tragic death, and through Mariska’s childhood.

Early life and immigration

• Born in Budapest, Hungary, on January 6, 1926 (Wikipedia (online encyclopedia)).

Acting career

• His physique landed him roles in European and American B-movies. He and Jayne Mansfield appeared together in four films: Will Success Spoil Rock Hunter? (1957), The Loves of Hercules (1960), Promises! Promises! (1963), and Primitive Love (1964) (Wikipedia).
• He also starred in horror cult classics such as Bloody Pit of Horror.

Marriage to Jayne Mansfield

Later years and death

What was Mickey Hargitay’s cause of death?

Health decline

• He had been in declining health in his later years but remained out of the public spotlight.

Date of death

• September 14, 2006, in Los Angeles, California (Wikipedia). He was 80 years old.

The catch: While Wikipedia lists multiple myeloma as the cause, many news obituaries at the time described it simply as “natural causes” or did not specify. The exact clinical cause has not been widely corroborated by medical records.

How many children did Mickey Hargitay have?

Children with Jayne Mansfield

• He had three children with Jayne Mansfield: Mariska (born 1964), Miklós Jr. (born 1959), and Zoltán (born 1962) (Encyclopaedia Britannica).

Other children

• He married Ellen Siano on April 14, 1968 (some sources say 1970). They remained together until his death in 2006 (Wikipedia).
