The first back inflatable may have been the "ATPAC", which even had a place in the hard pack to put large lead shot for ballast. It had a hinged door on the bottom of the hollow pack that opened to drop weights. I don't recall when they were first made, but I do remember seeing them in use in 1976.
Other early manufacturers of "wings" were ScubaPro and Seaquest. I tried the Seaquest wings by the late 70's, and never went back to other types after discovering the freedom and comfort.
