It is with great sadness that we share the news of the passing of our dear friend and longtime artist, John Simms.
For many years, John was a cherished part of the Diehl Gallery family. He remains the only Jackson Hole artist represented by the gallery—a distinction that reflects not only his extraordinary talent, but his deep connection to this place and community.
Visitors to the gallery were captivated by John's sculptures—the iconic bison, graceful kinetic forms, and works inspired by the landscapes and wildlife he loved so deeply. Yet before he became known as an artist, John had already lived several extraordinary lives.
A pioneering ski patroller, avalanche forecaster, inventor, entrepreneur, river guide, fisherman, and conservation-minded outdoorsman, John helped shape the culture of Jackson Hole during its formative years.
Frustrated by shortcomings in the fishing equipment available to guides, he founded SIMMS Fishing Products, a company that would become one of the most respected names in fly fishing worldwide.
What made John so special, however, was not simply what he accomplished. It was the way he moved through the world.
Many of us were fortunate enough to know John not only as an artist, but as a friend. We extend our deepest condolences to John's family and loved ones.
It was an honor to know him, to represent his work, and to call him our friend.
— The Diehl Gallery Family
