David Ira Hennagin


David Ira Hennagin, a 1981 graduate of Norman High School, passed away on August 2, 2019, after a valiant, year-long battle against pancreatic cancer, in Lakeway, Texas. A Memorial Service was held on August 6, 2019 in Lakeway.

Born in Philadelphia, Pennsylvania in 1963, David Hennagin later moved with his family to Los Angeles, Detroit, and Emporia, Kansas before arriving in Norman at the age of nine, when his father, a renowned composer, was appointed to the faculty of the University of Oklahoma School of Music. David spent the rest of his childhood and youth in Norman, graduating from Norman High School in 1981. An excellent student, he was then admitted to Grinnell College in Grinnell, Iowa, where he earned his Bachelor of Arts degree in Political Science in 1985.

After graduating from college, he returned to Norman for the next two years, during which David had his first experiences working in advertising. After that, for nearly thirty years, mostly in Los Angeles, and later in Kansas City and Austin, David pursued a stellar career that was studded with major successes in both the national and international arenas, including many award-winning advertising campaigns. In 2006, one of his Super Bowl commercials won the Emmy Award for Best Commercial of the Year.

When David moved to Los Angeles, California in 1987, he met his future wife, Jean Hagan. They married in 1989, settling in Los Angeles, and started their family. David and Jean had two daughters, Kylie and Shay, now 27 and 22, respectively. Kylie graduated from the University of Missouri School of Journalism in 2013, and is an advertising executive in New York City. Always an enthusiastic Sooners fan, David's loyalty to OU rubbed off on his daughter, Shay, who later attended the University of Oklahoma, graduating in 2018 with a degree in Advertising; like her sister, Shay is now also successfully embarked on an advertising career in New York City.

An avid fisherman, David loved to be out in his boat on Lake Travis in Texas, or at his summer home at Lake of the Ozarks. Riding through the Hill Country of Texas on his motorcycle, and playing rock music on his guitars were among his other passions, along with playing poker with friends, and eating good food. He will be remembered as a wonderful friend and neighbor, and as a generous and willing mentor to many of his co-workers who aspired to successful careers in his field. He also had a beautiful smile, which many spoke of at his Memorial Service.

David Hennagin was a devoted and loving husband, father, son, brother and uncle, and will be sorely missed by everyone in his family. He is survived by his beloved wife of thirty years, Jean Hennagin, of Lakeway, Texas; their daughters Kylie Hennagin and Shay Hennagin, both of New York City; his mother, Marijo Hennagin-Mazur, and stepfather, Dr. Vladislav Mazur; his sister, Melissa Hennagin Rames, and brother-in-law, Wendell Rames, all of Norman; his uncle, Daniel Fisher, of New York City; and many nieces and nephews.
He was preceded in death by his father, OU Professor Emeritus Michael Hennagin, and his beloved grandparents, Belmont and Dorothy Fisher, of New York City. In lieu of flowers, the family suggests that those interested make a donation in David's memory to the Pancreatic Cancer Action Network at www.pancan.org.
