Known as "Doc" Knight, he was an influential teacher, noted for his use of multi-colour chalk illustrations to teach geology over a span of fifty years.
Wilbur took up a position as a mining engineer at Florence, Keystone, west of Laramie and later became a state geologist.
At a young age Knight was introduced to geology, and collected fossils with Professor William Reed, curator of the University of Wyoming museum.
A skilled artist and designer, he was involved in making a life-size cast of Tyrannosaurus rex.
Knight also conducted outdoors science camps in geology at the Medicine Bow Mountains west of Laramie.
