I think it might have been Dave Hughes but I could be wrong.
In 1975 Sylvester Nemes began the re-introduction of sorts to traditional North Country spider patterns, including Pritts original North Country spiders, with the book The Soft-Hackled Fly. This book along with a string of others have kept traditional soft hackled spider patterns alive and well in the fly fishing community while introducing some innovative patterns to a new generation of fly anglers. Most recently Dave Hughes, who knew Pete Hidy, has kept the tradition of flymphs alive. In 1994 he wrote Wet Flies: Tying and Fishing Soft-Hackles, Winged and Wingless Wets, and Fuzzy Nymphs. This book has detailed descriptions of how to tie and fish fly patterns from Leisenring, Hidy, and Polly Rosborough.
