Betty Brosmer

In 2004, the Weiders donated $1 million to the University of Texas at Austin to support the physical culture collection of the H.J. Lutcher Stark Center for Physical Culture and Sports. The gift was key to the Stark Center's establishment of a permanent exhibition space, now known as the Joe and Betty Weider Museum of Physical Culture. The museum holds hundreds of items in its 10,000 square foot gallery space, and was opened to the public in August 2011.

With her husband, she authored two book-length fitness guides, The Weider Book of Bodybuilding for Women (1981) and The Weider Body Book (1984). With Joyce Vedral, she designed an all-ages workout regimen for women, published in 1993 as Better and Better.

In The Dirty Dozen (1967), pin-ups of Brosmer can be seen on the walls of the MP barracks. Posters of her are also seen hanging on gym walls in the documentary Pumping Iron (1977), and she makes a walk-on appearance as an audience member at a bodybuilding competition in Pumping Iron II: The Women (1985). She is portrayed by actress Julianne Hough in the Weider family biopic Bigger (2018).

After marrying magazine publisher Joe Weider in 1961, she began a lengthy career as a spokesperson and trainer in the health and bodybuilding movements. She has been a longtime magazine columnist and co-authored several books on fitness and physical exercise.

The two grew close due to their mutual professional and personal interests in fitness and psychology, and they were married on April 24, 1961. The marriage was Joe Weider's second, and he had one daughter from his previous wife; he and Brosmer had no children together. Their marriage would last over fifty years, until Joe Weider's death in 2013 at the age of 93.

After marriage, Brosmer (now known as Betty Weider) ceased posing as a pin-up, but she continued to be frequently photographed. For many years she was seen routinely in Weider publications helping to advertise a wide range of fitness products. She remained a highly visible presence among the various magazines, and was continuously included in their editorial photo work as well. Throughout the 1960s and 1970s, she appeared in many pictorial layouts, and also often on the covers of Weider titles like Jem, Vigor, and Muscle Builder. Her later cover appearances were often paired with champion bodybuilders of the day, such as Arnold Schwarzenegger, Dave Draper, Frank Zane, Mike Mentzer, and Robby Robinson; her final cover shot was on Muscle and Fitness in May 1988, with Larry Scott.

Playboy magazine pursued Brosmer for an exclusive pictorial, and a photo shoot was set up in Beverly Hills. The resulting picture set was rejected, however, after Brosmer declined to do any nude posing: "I wore sort of a half-bra or low demi-bra with nothing showing ... and that's what I thought they wanted." Playboy threatened a lawsuit over the alleged breach of contract, but ultimately relinquished the case. The photos were eventually sold to Escapade magazine and published in its anthology issue Escapade's Choicest #3 (1959). Brosmer never did any nude or semi-nude modeling throughout her long career: as she explained later in life, "I didn't think it was immoral, but I just didn't want to cause problems for others ... I thought it would embarrass my future husband and my family".

That future husband would turn out to be bodybuilding enthusiast and magazine publisher Joe Weider, who had first become aware of Brosmer through his contact with Keith Bernard for fitness models. Brosmer's first photos for a Weider magazine appeared as a four-page layout in Figure & Beauty in December 1956. After that, Weider regularly sought out her work among Bernard's submissions. She was known to be his favorite model and he requested her more and more frequently after their first face-to-face meeting in 1959.

Brosmer returned to Los Angeles and was soon asked to pose for two of the most celebrated pin-up artists of the era, Alberto Vargas and Earl Moran. Encouraged, her aunt took her back to New York City again in 1950, and this time they took up residency. Brosmer built her photographic portfolio while attending George Washington High School in Manhattan. Despite her age, over the next four years Brosmer found frequent work as a commercial model, and graced the covers of many of the ubiquitous postwar "pulps": popular romance and crime magazines and books. As she explained, "When I was 15, I was made up to look like I was about 25".

Some of her most famous photo work during this period include glamour appearances in Picture Show (December 1950, cover); People Today (July 1954, centerspread); Photo (January 1955); and Modern Man (February 1955; May 1955). She was also employed as a fashion model, and in 1954 posed for Christian Dior.

She won numerous New York area beauty contests in the early 1950s, most famously "Miss Television"; in that capacity she appeared in TV Guide, as well as on the widely seen programs of Steve Allen, Milton Berle, Jackie Gleason and others. Her fame had grown so much by the age of eighteen that when she left New York and returned to California – this time to Hollywood – her departure was noted in the celebrity column of Walter Winchell.

Back on the West Coast, Brosmer maintained a busy freelance workload in fashion and commercial modeling, while at the same time continuing her education, majoring in psychology at UCLA. She also entered into a lucrative contract with the glamour photographer Keith Bernard, and she worked steadily with him for the rest of the decade. For Bernard, a well-established photographer who had worked with Marilyn Monroe and Jayne Mansfield, Brosmer would prove to be the top-selling pin-up model of his career. Brosmer's publication work during the late 1950s includes appearances in Modern Man (October 1956, cover); Photoplay (April 1958, cover); and Rogue (July 1958 and February 1959, covers). During this time, Brosmer was said to be the highest paid pin-up model in the United States – she was seen in "virtually every men's magazine of the era".

Betty Chloe Brosmer (born August 2, 1935), later known by her married name Betty Weider, is an American former bodybuilder and physical fitness expert. During the 1950s, she was a popular commercial model and pin-up girl.
