My nominations go to three local guys from the pre-royalex era. Roger Corbett, canoeist extraordinaire and author of Virginia Whitewater.
The third local guy that impresses me is Ed Gertler. He has written guidebooks on Maryland, Delaware, Pennsylvania and New Jersey. Paddles a C1 of some sort which is no longer in production, but he has the mold, so when he wears them out he gets another one built. And I believe he does wear them out, for he paddles (fast) the rivers in the guidebooks
Turns out, Corbett had also mentored Gertler, and that must have been back around 1970-80. Gertler was this kid who wanted to paddle but wasn't old enough to drive, and Corbett would go pick him up and take him paddling. Later, Gertler tried to talk Corbett into writing a guidebook for Maryland. Corbett turned the tables on him. He refused to write the guidebook but encouraged and helped Gertler to write it. So not only did Corbett train paddlers, he developed a prolific guidebook author, and I never heard of him accepting payment for any of it.
So, these guys get my hero nominations, not only for their considerable paddling prowess, but for a lifetime of helping others enjoy paddling and giving back to the paddling community.
