Tau brother and 2010 Kappa Sigma Tau Man of the Year Hagen McMahon passed away on 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 represented banking interests at the Texas Legislature and in Congress and served as an advisor to four Presidential Administrations on matters concerning banking legislation and federal regulations.
He was devoted to Kappa Sigma Fraternity and served in several alumni leadership roles for the Tau Chapter. He oversaw the design and construction of the Kappa Sigma Lodge in 2010 and Warren Residence Hall in 2016. Kappa Sigma National Fraternity honored him with the John G. Tower Distinguished Alumni Award in 2005. The Tau Chapter chose him for the Frank C. Erwin Award in 2005, 2006, and 2007. He was honored as Kappa Sigma Tau Man of the Year in 2010.
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.
He is survived by his loving wife, Susan; son, William Wroe "Beau" McMahon; son, Fred Hagen McMahon III and his wife, Victoria Sicola McMahon; daughter, Wynne McMahon Kennedy and her husband, John Kennedy; four grandchildren: Avery, Lucy, Walker, and Hagen IV; sister, Carolyn Kirklin, nephew, Brad Kirklin; niece, Meaghan Kirklin Conrad; and a host of extended family members with whom he remained close throughout his life.
Hagen's life will be celebrated on Wednesday, October 11 at 1 PM at The Episcopal Church of the Good Shepherd, 3201 Windsor Road, in Austin.
Tau Brothers Bid Farewell to Hagen (a few of the messages sent to Hagen before he passed):
Hagen, I want to tell you how much your friendship and leadership have meant to me over the past 15+ years. Thank you for all you've done for our beloved Tau Chapter.
We went to a lot of places and did some cool things together: Vegas (more than once), New Orleans, Port Aransas, and multiple Cooley golf tournaments. I loved all your stories and learned a lot from you. We will always be brothers!
AEKDB,
Jim Pritchett '71
Hagen, You have been my mentor for 20+ years. I consider you a good friend and a brother in heart for life. What you have accomplished for the Tau Chapter is exceptional. You epitomize our creed, "The Star and Crescent."
AEKDB,
Bill Zwiener '73
Hagen, You're the man! When I met you and Dan Burck for the first time over lunch, I realized I had just met two of the greatest Sigmos ever. It inspired me to take a leap of faith that continues today. We're brothers in arms forever.
AEKDB,
Reggie Tuck '69
