I'd say first place should go to Cordwainer Smith ( https://en.wikipedia.org/wiki/Cordwainer_Smith ) though I have a soft spot for Clifford Simak ( https://en.wikipedia.org/wiki/Clifford_Simak ), not to mention Jack Vance ( https://en.wikipedia.org/wiki/Jack_Vance ). None of them are exactly unknown, but I don't think they get much credit these days for having influenced FSF.
