Pamela Tiffin Wonso was born in Oklahoma City in 1942 and grew up in Chicago, where she began a modeling career at a young age. She moved to New York to pursue modeling and attend college, but her success in the modeling world soon overshadowed her academic pursuits. During a trip to California, she caught the attention of producer Hal B. Wallis, who was so impressed with the beautiful teenager that he cast her in the Tennessee Williams drama Summer and Smoke in 1961.
Tiffin's performance in Summer and Smoke earned her nominations for two Golden Globe awards, including Best Supporting Actress and Most Promising Female Newcomer. Later that year, she married American journalist, editor, and magazine publisher Clay Felker. She continued to work in the entertainment industry, posing for cheesecake shots and appearing in several lighthearted romantic comedies. Her comedic skills caught the attention of legendary director Billy Wilder, who cast her in the Coca-Cola-themed film One, Two, Three in 1961.
Tiffin went on to appear in a number of other comedies, including The Pleasure Seekers, For Those Who Think Young, and Harper. By the mid-1960s, her marriage was ending, and she moved to Italy to star in a series of comedies, including Straziami ma di baci saziami in 1968. In these films, she demonstrated her ability to adapt to a small-town Italian girl and received critical acclaim for her performances.
Tiffin retired from the screen in 1974, after remarrying to Edmondo Danon. She and her husband raised two daughters in New York and pursued other interests. Tiffin passed away in 2020 at the age of 78, leaving behind a legacy as a talented actress and model who made a lasting impact on the entertainment industry.
