Early Life

Mary Higgins Clark was born Mary Theresa Eleanor Higgins on December 24, 1927, in The Bronx, New York. She was the daughter of Luke Joseph Higgins and Nora C. Durkin, and Luke was an Irish immigrant. Mary had two brothers, Joseph and John, and sadly, Joseph died not long after graduating from high school when he contracted spinal meningitis while serving in the Navy. Higgins Clark wrote her first poem when she was 7 years old, and as a child, she often wrote short plays. The family owned an Irish pub and had a home in The Bronx as well as a cottage on Long Island Sound, but they began experiencing financial difficulties in the late 1930s because many of the pub's patrons couldn't pay their bar tabs due to the Great Depression. In 1939, Mary's father died in his sleep, and her mother had to force Higgins Clark to move out of her room so she could rent it to boarders. Mary attended Saint Francis Xavier Grammar School, then she earned a scholarship to study at Villa Maria Academy, where the teachers encouraged her interest in writing. She took a job as a switchboard operator at the Shelton Hotel to help her family pay the bills. The family eventually lost their house and moved into an apartment. After Joseph died, the Navy guaranteed Nora a life pension, and Mary no longer had to help her pay the bills.


After attending Wood Secretarial School, Higgins Clark began working as a secretary in Remington Rand's internal advertising division. She went to night school to study advertising and promotion, and she eventually started writing catalog copy for Remington Rand as well as modeling for their brochures alongside future star Grace Kelly. Mary later worked as a flight attendant for Pan American Airlines, but she gave up the job when she married Warren Clark in December 1949. She then studied writing at New York University, and in 1956, her short story "Stowaway" was published by "Extension Magazine." The day Higgins Clark accepted a job writing radio scripts in 1964, Warren had a fatal heart attack, and his mother collapsed and died after discovering that her son was dead. After Mary began writing four-minute scripts for the "Portrait of a Patriot" radio segment, she was asked to write two additional radio series. By the late '60s, magazines had stopped publishing short stories the way they once did, so Higgins Clark's agent encouraged her to write a novel. The result was "Aspire to the Heavens," a fictionalized account of George and Martha Washington's relationship. The novel was published in 1968, but it was "remaindered as it came off the press." In 1971, Mary enrolled at Fordham University at Lincoln Center, and in 1979, she graduated summa cum laude.

Mary and Warren welcomed five children together: Marilyn, Warren Jr., David, Carol, and Patty (named after Higgins Clark's agent, Patricia Schartle Myrer). As children, Patty was a Gerber Baby, and David appeared in a United Way ad. Carol followed in her mother's footsteps and became a mystery writer, and the two co-wrote several novels. David was previously married to Mary Jane Clark, an author known for writing the "Key News" suspense novels and the "Wedding Cake Mysteries" series, and their son, David, has a developmental disability called Fragile X Syndrome.
