E.R. Hewitt was one of the most extraordinary individuals New York has ever known.. He was a chemist, inventor, innovator and a truly great fisherman. His keen interest in trout fishing led him to purchase four and a half miles on the Neversink River in 1918 where he created a hatchery and laboratory. Soon after, Hewitt was recognized as a leading authority on stream management and improvement. As an author, he penned several books on angling. As an inventor, he held numerous patents, including the felt soled wading shoe, a fishing line grease, an opaque leader, in interchangeable fly reel and a bivisible trout fly. His innovations make him one of the greatest contributors in the history of fly fishing.
