Lee Wulff and Q. L. Quackenbush independently adapted the Royal Coachman in 1929-1930. When the fly started being tied on a commercial level by Rube Cross, the variations were named Quack Coachman, Hair-winged Royal Coachman and Quack Special. Later in the 30’s Dan Bailey convinced Lee Wulff to rename the flies, and from then a variety of other flies were chnaged and renamed such as the Ausable Gray, Coffin May and Bucktail Coachman became the Grey Wulff, White Wulff and Royal Wulff.
“The Wulff flies were designed by Lee Wulff and fill a decided need in large sizes. I consider them necessary to the well-balanced fly box. New Wulff patterns, Black Wulff and Grizzly Wulff [designed by Dan Bailey] have been added to my color plates because they are considered very important by fishermen in the Rockies as well as other sections.”— Ray Bergman, Trout (1952)
