A native of Dallas, he came to us from Highland Park High School. At Princeton he majored in biology, played JV football, took his meals at Tiger Inn, and was a member of Whig-Clio and the Texas Club. He roomed with Joe Messina, Ed Rose, Woody Andrew, and Sandy Falconer.

Following Princeton Mac earned a medical degree and a Ph.D. at Baylor College of Medicine, then interned in San Francisco and took his residency in New Orleans. After a cardiology fellowship at the University of Alabama at Birmingham, he entered into private practice in Jackson and then joined the Jackson Heart Associates and St. Dominic, whence he retired in 2014. Mac was active in his community and church, was an avid fan of both Alabama and Ole Miss football  (no mean feat), and was a member of the Sports Car Club of America and Formula V Racing, as well as patron of the arts at the Mississippi Museum of Art and New Stage Theater.

He is survived by his wife of 56 years, Martha; two sons and their families, which include five grandchildren; and his brother, Thomas ’64.
