Scientific Anglers
Scientific Anglers began with three men (Leon P. Martuch, Clare Harris, and Paul Rottiers) and a single vision, transposed into a company spanning across the globe, influencing the way modern fly fishermen interpret and practice our sport. The cast, the rods, the reels, and the flies all connect through the cotter pin of fly fishing: fly line. Scientific Anglers became the unequivocal champion of fly-line production through leading market innovation and development during fly fishing's early widespread appeal.
