Marilyn Hanold, a ravishing brunette born on June 9, 1938, in Jamaica, Long Island, New York, was the second of six children. Her ancestry was of German descent, and her father was a lieutenant in the New York City police department. After graduating from the World Secretarial School in New York, Hanold worked as a legal secretary for a prominent patent attorney for 18 months.
In August 1957, she joined the chorus line of the El Rancho in Las Vegas, Nevada, where she was later featured in the tabloid revue "Scandalettes" and became a showgirl at Ciro's. Her talent and beauty did not go unnoticed, and she was soon working as a showgirl at Frank Sennes' "Moulin Rouge" in Hollywood, California.
It was during this time that a representative from the William Morris Agency spotted Hanold and introduced her to George Gobel's new stage production "Riviera Revue." Her cover appearance on the February 1959 issue of "Photo Life" magazine and her subsequent feature as the Playmate of the Month in the June 1959 issue of "Playboy" cemented her status as a Hollywood sensation.
Throughout the 1950s and 1960s, Hanold appeared in a few films and television shows, further solidifying her reputation as a talented and captivating performer. In 1967, she married oil tycoon Rulon Keaton Neilson, with whom she had three daughters.
Today, Hanold resides in Salt Lake City, Utah, where she remains actively involved in charitable and social events in the local community.
