From the Dorsey Funeral Home

John A. Markisz, M.D., Ph.D., 79, of Briarcliff Manor, NY, died on June 10, 2021 from complications of heart disease. He retired in December 2020 as a partner of Radiologic Associates in Middletown, NY, where he was a Nuclear Medicine Radiologist.

Beloved son of the late Anthony and Adele Markisz of The Bronx, NY, he leaves behind his brother Robert Markisz, sister-in-law Susan (nee Bibb) Markisz of The Bronx, NY, his nephew Christopher Markisz (Joanny Rivera) of San Anselmo, CA and niece Kathryn (nee Markisz) and Donald Fox, and a grandniece, Adele, of Asheboro, NC. Adele, born in 2019, was named after her great-grandmother Adele, loving matriarch of the family who died six weeks shy of her 100th birthday in 2014. John’s many cousins including first cousins Karol McGregor, Anne Louise (nee Markisz) Spero, Lucille Markisz and Joe Markisz will miss him dearly.

Born on March 5, 1942 in New York City, John was raised in The Bronx. He earned a Bachelor of Arts in Chemistry with highest honors from New York University in 1962, and a Ph.D. from New York University in 1966. He was a professor of chemistry and physics at Columbia University and the City University of New York.

Mid-career, John applied to medical school and received his medical degree from the University of Miami School of Medicine in 1980. He completed a medical internship at Brigham and Women’s Hospital, a major teaching hospital of Harvard Medical School in 1981, and a Nuclear Medicine residency at Brigham and Women’s Hospital in 1982. In 1984, Dr. Markisz completed his residency in Diagnostic Radiology at The New York Hospital and served as Clinical Director of MRI at The New York Hospital Weill Cornell Medical Center. He was Board Certified in Nuclear Medicine by the American Board of Nuclear Medicine in six states. He was the author of eight books and the recipient of many citations on the subject of Radiology.

John was a devoted family member, travelled widely and enjoyed opera. For many years, he, his brother Bob and sister-in-law, Susan, had a subscription on Saturday nights to the Metropolitan Opera. Among his favorites were Tosca, Aida and Donizetti’s “Three Queens” trilogy. In 2016, the three saw their last opera together with Sondra Radvanovsky in Roberto Devereux at the Met, a highlight all agreed was one of the best performances they’d ever seen at the Met. Shortly before he died, John, together with Bob and Susan, listened to Beverly Sills’ rendition of Elisabetta in New York City Opera’s performance of Roberto Devereux.
