He was a valued member of the golf team from 1970 to 1974 and enjoyed alumni golf more recently. He followed Princeton sports fanatically; when Princeton basketball broke Penn’s unbeaten record, he cut the net down and gave it to the star player, a friend. Mack was a beloved member of Cottage Club, where he regularly lost in beer pong to lifelong friends who never let him forget it. Mack was a lover of history, his major. As an undergraduate he was also a wonderful entertainer, often hosting friends in his room.  

He found joy throughout life preparing delicious food accompanied by fine wine and good conversation.  

Mack spent his legal career fighting age discrimination in employment while working for the EEOC, AARP, and private firms. He often spoke on behalf of older workers in local and national media. Mack found post-collegiate outlets for his athleticism in golf, and he documented hikes in the American Southwest with beautiful landscape photographs.  

Mack is survived by his daughter, son, brother, sister, and former spouse. The family welcomes in-memoriam donations to the V Foundation (“Victory Over Cancer”) or the National Parks Foundation.
