If you have ever stood in awe at a Disney park, lost in the immersive thrill of a 360-degree film or the heart-pounding realism of a motion-base simulator, you have experienced the genius of Don Iwerks.
The entertainment world lost a true visionary on July 9, 2026, when Don Iwerks passed away at the age of 96. For fans of theme parks and cinema, his name stands alongside the architects of our favorite childhood memories. His passing marks the end of a six-decade career that fundamentally transformed how we experience storytelling.
Don’s journey with The Walt Disney Company began in 1950, when he joined as a laboratory technician. Following in the footsteps of his father, the legendary animator and Disney pioneer Ub Iwerks, Don quickly proved he had the same “can-do” spirit and technical brilliance.
His contributions to the Disney parks and film industry are nothing short of legendary:
Circle-Vision 360: Don was pivotal in advancing this immersive technology. He helped develop the multi-camera systems that allowed guests to be surrounded by spectacular visuals in films like America the Beautiful.
The Sodium Vapor Process: Working closely with his father, Don helped perfect the revolutionary sodium traveling matte process, which seamlessly blended live-action and animation—a key piece of magic in the beloved film Mary Poppins.
Iconic Attractions: Don’s engineering expertise brought attractions like Captain EO and Star Tours to life. He helped develop the synchronized projection systems that perfectly matched the motion-base simulators, creating the high-energy, immersive experiences we still enjoy today.
World’s Fair and Epcot: Don often cited his work on the 1964–65 New York World’s Fair and the creation of Epcot as the defining moments of his career, where he helped build the advanced equipment that paved the way for “Disneyland East”.
After leaving Disney in 1986, Don continued to push boundaries by co-founding Iwerks Entertainment, which became a global leader in giant-screen theaters and virtual reality experiences.
Throughout his life, he received numerous honors for his contributions to the film industry, including the Academy of Motion Picture Arts and Sciences’ Gordon E. Sawyer Award and his induction as a Disney Legend in 2009.
Today, if you visit the Magic Kingdom at Walt Disney World, you can find a tribute to him and his father: a window on Main Street, U.S.A. dedicated to the “Iwerks & Iwerks Stereoscopic Cameras.” It serves as a permanent reminder of a man whose heart, ingenuity, and passion helped shape the very fabric of the Disney magic we love to explore.
Our thoughts go out to the Iwerks family during this time. Thank you, Don, for the countless adventures you made possible.
