Laurel Cutler, a female advertising executive in the testosterone-driven “Mad Men” era of 1960s New York, died Nov. 28 at her home in Manhattan. She was 94.

During her five-decade career on Madison Avenue, Ms. Cutler was the only women on Fortune magazine’s list of 11 “seminal thinkers” of the 1980s. Ladies’ Home Journal called her one of the 50 most powerful women in America in 1990, noting that she could get her phone calls returned. The Advertising Federation of America named her “Woman of the Year” in 1985 and “Man of the Year” 10 years later. She was inducted into the Advertising Hall of Fame in 2011.

Laurel Cutler’s brother, Lloyd Cutler, became a highly successful lawyer in Washington and counselor to Presidents Jimmy Carter and Bill Clinton. In her memoir, she recalled a reception in Washington where she was introduced to Katharine Graham, publisher of The Washington Post, as “Lloyd’s sister.” At that, Edward N. Ney, chairman of Young & Rubicam, stepped in to tell Mrs. Graham, “In our world, he’s Laurel’s brother.”
