Mary Wells
In 1966, Wells became the first woman to head a major agency, Wells Rich and Greene, and earned the honor of being the first female CEO of a company listed on the New York Stock Exchange.
In her 2002 memoir she wrote, "I began to theatricalize what I sold." As a result, her agency created memorable jingles, such as Alka-Seltzer's "Plop, Plop, Fizz, Fizz" and Ford's "Quality is Job One."
In 1990, she sold Wells Rich and Greene for $160 million to a French company that eventually closed the firm.
