Agnes Miriam Cohen Bogart, who summered in Amagansett and East Hampton for many years, died on Oct. 4 of lung cancer and pneumonia at Roosevelt Hospital in Manhattan. She was 97.
Ms. Bogart began her career as a union activist, working for the Non-Partisan League in Chicago and the Reuther brothers, who were key in organizing the auto industry, in Detroit.
She subsequently worked at the American Management Association in New York City, where she was an associate editor at Personnel and Management Review magazines. She later launched the firm’s Compensation Review title. After working for the National Foremen’s Institute as an editor, she joined Industrial Relations Research Counselors.
She was next hired by the Equitable Life Assurance Society of New York to head its publications program, then became its director of public relations and human resources management.
She retired when she was 76, though continued with the Volunteer Referral Agency and Women’s City Club.
She was born on June 23, 1916, in Quincy, Ill., to Frank Cohen and the former Constance Plaut. She attended Quincy High School and the University of Wisconsin and graduated with a degree in economics from the University of Chicago.
She and Leo Bogart married in 1948, and they spent a year together in Europe from 1950 to 1951 while Mr. Bogart was studying as a Fulbright scholar. They began spending weekends in North Sea in the 1950s.
Travel was an important part of their work and professional lives. Ms. Bogart was especially passionate about France and the great houses of England, her family said.
In the early 1960s, the Bogarts rented in East Quogue and on Hedges Lane in Amagansett, before buying a house in the then-new development at Hampton Waters. After their retirement, they moved to Amagansett, keeping an apartment in Manhattan as well.
Ms. Bogart was described by her family as a master chef and dinner host, known for her Chinese cooking. She was also a health enthusiast who took up yoga while in her 70s. She worked out on a treadmill and rode a bicycle well into her 90s.
The family remembered her as “cool, calm, and unflappable in emergencies” such as hurricanes and power outages. She loved crosswords puzzles, her cocktails, and a full glass of wine, and had a “dry sense of wit and a wickedly sarcastic streak.” They said she was a “powerful example of courage and dignity in aging” as well.
Mr. Bogart died before her. She is survived by a son, Greg Bogart of Richmond, Calif., a daughter, Michele Bogart of Brooklyn, two siblings, Joanne C. Powers of Chicago and George H. Plaut of Puerto Rico, and a grandson.
She was cremated in a private service.
