If you look at history, I think you're in good company.
I think the following people fit this case:
* Vincent van Gogh (no one used his paintings)
* Ted Nelson (no one used his version of hypertext)
* Douglas Engelbard (really ironic when you think about it, made all kinds of multimedia prototypes and it took 50 years and his name is nowhere to be found)
* Ignaz Semmelweis (really really unfortunate, relied on very primitive correlational analyses on childbed fever, got the treatment right -- hand washing -- yet no one believed him while he was alive)
People that didn't make the cut:
* Alan Turing (people did use his Enigma, I thought about him for a second because of how the British government treated him)
* Stanislav Petrov (many people "used" his "product" without anyone knowing, I considered him because still too few people know about this hero)
