James Joseph McDuffie, II, affectionately known as J.J. or Mac passed away on January 24, 2024. He was born to Sara and James McDuffie, MD, in Washington, DC July 8, 1950.

J.J./Mac attended St. Marcus Lutheran School and Wisconsin Lutheran High School where he participated in football, wrestling, track, jazz band, marching band, L Club, and Electronics club. He attended the University of Wisconsin - La Crosse, the University of Wisconsin - Madison and MSOE.

J.J./Mac had many interests and loves including scuba diving, auto racing, guitars, music, collecting coins, collecting miniature race cars, greeting cards, photography and much, much more. He loved watching old TV, westerns ☺, NCIS, Miami Vice, Law & Order and of course, Wisconsin Badgers football, Milwaukee Bucks and Green Bay Packers. He totally enjoyed Pepsi, Gummy Life Savers, Snickers, grits, Chinese food, pizza w/anchovies, peanut M&M’s & popsicles. Later in life, he developed an interest in the medical field, so he went back to school for nursing. Unfortunately, because of health issues he wasn't able to finish.

Being predeceased by our parents, and our brother David, J.J./Mac is survived by sisters Ruth (Chuck Marks) and Tamye (Dave Metzger). He was uncle to Alex, Kaelyn, Sara, Aliea, Jessica, and furry nephew Ziggy. He is further survived by his wonderful home caregivers, Gigi and Demetris and many, many close friends and racing buddies.
