They were invented by Douglas Niever, who suffered a terrible accident as a teen, and so had no hands with which to pull down on paper towels...

I cannot find out who invented the original versions.
but I have found that James Dyson; of bagless, cyclonic vacuum cleaners fame; has introduced a super new model.
Dyson Airblade
The newest Dyson is the Dyson Airblade hand dryer. The Airblade is aimed at commercial use.
The Airblade uses Dyson’s new Dyson Digital Motor (DDM) to produce a stream of air that flows at 400mph acting like an invisible windscreen wiper to dry the hands.
The Airblade also used Dyson’s HEPA filter to remove bacteria and mould from the air.
Waste water is passed through an iodine resin filter to disinfect it.
