Born in Detroit and raised in Ventura, Calif., Mac graduated from Ventura High School, where baseball and basketball were his sports. At Princeton he continued with basketball, joined Tiger Inn, and undertook premed courses. He left us after junior year to study medicine at Oxford University, UK. Returning to the United States, Mac went on to the University of Michigan Medical School, where he earned a medical degree in 1963. At UCLA he completed his residency in ophthalmology in 1967 and undertook two years service in medicine with the Army, rising to the rank of major.
Mac specialized in ophthalmology and pioneered in the treatment of retinal diseases, first at Duke University’s Eye Center (where he was awarded his Princeton A.B.) and the University of California, Davis. He spent some years in private practice before returning to academia at the University of North Carolina from 2001 to retirement in 2019.
International travel was his preferred recreational pursuit. He prided himself on having traveled to 35 countries and almost every continent.
Mac died July 11, 2021. He is survived by his wife of 25 years, Wendy; three children; and five grandchildren, to whom we send our condolences.
