Harold Solomon Marcus was born on May 20 1933, in Flatbush, NY, to Annette and David Marcus. He had 2 younger siblings, Myra and Jerry. He attended Lafayette High School and NYU as an undergraduate. He then got a full scholarship to attend NYU School of Medicine.
In 1954 he met Eve Zagoren on a blind date. They stayed out until 2 am talking, and discovered that their mothers had been friends as teenagers. After a 3 year courtship seeing each other only every other weekend, they married at the end of Harold's 3rd year of medical school. Eve taught elementary school to support them until Harold graduated.
The couple moved to Columbus Ohio in the summer of 1958 where Harold completed residency at Ohio State University Hospital in Internal Medicine. In 1960 he joined the Navy, having deferred being drafted. They moved with their first daughter Elaine back to Brooklyn, so Eve could be near family while Harold was at sea. Their second daughter Beth was born during this time. After Naval voyages taking Harold to Africa, Europe and the Far East the family moved back to Columbus in 1962 so Harold could complete a fellowship in Cardiology.
He became one of the first generation of cardiologists to perform coronary angiography, at a time when bypass graft surgery and other forms of open heart surgery were being developed. The family moved to Los Angeles in 1966 (his parents and siblings preceded them) where Harold became the director of the new Cardiac Cath Lab at Cedars of Lebanon Hospital. Here the third of their daughters, Madeline, was born. He went on to direct the cath lab at Cedars-Sinai Medical Center, and also directed the Cardiac Intensive Care Unit there for a time. In these professional capacities he trained hundreds of medical students, residents and cardiology fellows, and touched the lives of thousands of heart patients. His charismatic personality made him a well-known figure in medical circles in L.A., and those who knew him often quoted his aphorisms and quips. In the early 80's he opened a private cardiology practice with several other physicians, and he continued to see patients and perform procedures until his retirement in 2001. Harold found medicine fascinating, and even after his retirement continued to work at Cedars doing administrative review of patient care.
Widely read, interested in art, history and classical music, Harold was also very mechanical. He could fix anything, or at least try to. He had a prodigious vocabulary, seemed to know something about everything, and was happy to share his knowledge. He and Eve were passionate cooks, reading cookbooks to one another, and preparing exotic ethnic dishes for family and friends. They also traveled widely, and came home talking about all the interesting things they'd eaten. He was active with his synagogue, Adat Ari El, and he and Eve have been members of a Chavurah (friendship group) there since 1970.
He was dedicated to family, supporting his daughters through their educations. All three became physicians. When his twin grandsons Adin and Jonah Ring were born in 2000 he became the most loving, patient and interested of grandfathers, delighting in all they did.
Harold Solomon Marcus died July 8, 2013 after a long illness. He is survived by his wife Eve Marcus, his daughters Elaine Marcus, Beth Marcus (Jeffrey Ring), and Madeline Marcus (Glenn Simpson), his sister, Myra Feffer (Amnon) and brother Gerald Marcus (Ann), and grandsons Adin and Jonah.
