F. Hagen McMahon Jr.

November 16, 1942 - October 1, 2023

Hagen McMahon passed away peacefully in his Austin home on Sunday, October 1, embraced by the love of his family. He was a one-of-a-kind, larger-than-life, true Texas gentleman who loved people, animals, adventure, and the challenge of negotiating a win-win business deal.

He was involved in bank management, governmental relations, business consulting, investment banking, and oil and gas interests for more than 50 years.

He served as executive director of the Independent Bankers Association and represented their interests at the Texas Legislature and in Congress. During his banking career, he served as an advisor to four Presidential Administrations on matters concerning banking legislation and federal regulations.

He was an enthusiastic Kappa Sigma brother and served in various leadership roles as an alumnus of the University of Texas Tau Chapter. He oversaw the design and construction of the Kappa Sigma Lodge in 2010 and Warren Residence Hall in 2016. He was chosen in 2010 as the Kappa Sigma Tau Man of the Year, the highest honor bestowed to a Kappa Sig alum by the University of Texas Tau Chapter. In 2005, Kappa Sigma National Fraternity honored him with the John G. Tower Distinguished Alumni Award. The Tau Chapter honored him with the Frank C. Erwin Award in 2005, 2006, and 2007.

His priority was his family and close inner circle of friends. He was known for his sterling character and as a rainmaker for helping many people in their careers.

He loved the ocean and family time at Port Aransas, boating trips in the Pacific Northwest, the San Juan Islands, and the Mediterranean Sea. He was a licensed pilot, scuba diver, and entertaining raconteur.

He earned a Bachelor of Business and Economics from UT Austin and an MBA from the Southwestern Graduate School of Banking at Southern Methodist University.

His survivors include his loving wife, Susan, son William Wroe "Beau" McMahon; Fred Hagen McMahon III and his wife, Victoria Sicola McMahon; Wynne McMahon Kennedy and her husband, John Vandervoort Kennedy; four grandchildren, Avery, Lucy, Walker, and Hagen IV; sister, Carolyn Kirklin; nephew Brad Kirklin, his wife, Natalie, and their three children; niece Meaghan Kirklin Conrad, her husband, Charles, and their two children; and a host of extended family members with whom he remained close throughout his life.

We will celebrate his extraordinary life on October 11 at 1 p.m. at The Episcopal Church of the Good Shepherd in Austin. In lieu of flowers, we ask that you donate to Austin Pets Alive!, Final Frontier Rescue Project, or the Capital Area Food Bank of Texas.
