Actually, he was just shy of 93 when he died. Among other things, he was a veteran of the Battle of the Bulge.
I met Lefty several years ago. He signed a book for me at the Atlanta Fly Fishing Show. (I saw him for the last time at the 2017 show). An amazing caster, he could cast the entire fly line with just his hands. He was not a big guy. I'm about 5'7", and I towered over him.
He has a bunch of videos on Youtube, and he's featured on the fishing show, "Buccaneers and Bones".
Check him out.
