He founded a little media outlet called In-Fisherman back in 1975. Written countless books on fishing, as well as producing a ton of videos. He is considered to be one of the best all around anglers in the world and has been inducted into many different "Halls of Fame" for fishing. He is very involved in conservation efforts. He invented one of the most popular walleye fishing rigs, the Lindy Rig. He also has been very involved in teaching youth how to fish. One of his books about LMB, written in the early 90's is still one of the most highly regarded books out there.
