After graduating with a degree in architectural history, she married Yale Law student Andy Stewart, had a daughter, Alexis, in 1965, and worked on Wall Street as the only female stockbroker at her firm. “The job taught me so much about what it takes to build a real business, a real company—a meaningful and useful enterprise,” Stewart later recalled. Raised by parents who passed on their love of cooking and gardening, Stewart left Wall Street in the mid-’70s to start a catering company out of the basement of Turkey Hill, her iconic former residence in Westport, Connecticut.
