In 1894, world's first glider club:
Mohawk Aerial Navigation Company, Ltd.
spawned from excitement over the flying man Otto Lilienthal. Man-carrying flex-wing kite and hang gliders .... efforts made; membership grew at $2 per head, but waned.
Leader founder: Charles Proteus Steinmetz, the "wizard of Schenectady. (Ref.: p. 170-172 of Tom D. Crouch, A Dream of Wings)
I nominate Steinmetz as historical member of US Hawks chapter Mo Hawks.
The full story of that club, their interesting constructions and efforts, their pseudo-photo-retouch-membership-drive effort in a waning period ... and more
is invited by anyone finding information and photographs, etc.

[ ]The wiki is yet poor for not yet showing Steinmetz's involvement in matter of Mohawk Aerial Navigation Company, Ltd.
There is a connection with another part of hang glider history...tenuous. In Breslau a gliding club reached our cable-stayed triangle control frame with pilot hung from keel on hang glider. Steinmetz went to University of Breslau before he came to United States.
