The founder of Zarin Fabrics has long battled the disease, first being diagnosed with thyroid cancer in 2009. He went on to have his thyroid removed as well as underwent radioactive iodine treatment.
The cancer returned and spread to his lungs. In fall 2016, Jill revealed to PEOPLE that Bobby was diagnosed with a brain tumor and underwent Gamma Knife Radiosurgery at MD Anderson Cancer Center in Houston.
Unfortunately, she said “his cancer took an unexpected turn” over the summer. In July, Bobby was admitted to Memorial Sloan Kettering Cancer Center in New York City, where he recovered from a procedure.
“He is not going down without a fight,” Jill told PEOPLE exclusively. “We’re hoping for a miracle.”

“He is the most loving and caring person I have ever known besides my father. Sometimes life just isn’t fair,” Jill previously told PEOPLE about her husband of 18 years. “But we have such a great love story. He is the love of my life and I will do everything in my power to heal and care for him.”
Bobby ran Zarin Fabrics, which was opened by his father, Harry Zarin, in 1936. The New York native is survived by Jill, his three children — Jonathan, David and Jennifer Zarin — and stepdaughter, Ally.
