Born in North Adams, Massachusetts, Melcher began his career working as an agent and road manager for The Andrews Sisters and eventually married Patty Andrews on October 19, 1947. The couple divorced on March 30, 1950. Slightly more than a year later, he married Day, and they formed their own production company in 1952.
Shortly after his death from a heart attack, Day discovered Melcher had committed her to a CBSsituation comedy without consulting her, and that not only had he lost the millions she had earned throughout their marriage due to poor investments, but he had left her seriously in debt as well. She sued his partner Jerome B. Rosenthal and was awarded nearly $23 million for fraud and malpractice following a 99-day trial. Rosenthal declared bankruptcy, and in August 1977 Day settled with his insurers for $6 million that was paid in twenty-three annual installments [2].
