The Oatmeal had this comic strip back some time back about Nikola Tesla, one of my personal favorite inventors who was generations ahead of his time.
Without Tesla, a lot of technologies would not be possible, from AC current electricity to RADAR and even X-ray technology. I've never been too enamored with Edison to begin with, and the more I read about him, the less I like him. Edison was a charlatan who stole others' ideas and pushed them as his own, while blue-collar tinkerers like Tesla really pushed new technologies and incredible ideas, often from science fiction to science fact. One project I did in vocational school was to create a Tesla Coil, which was a lot of fun.
Part of the comic is below (reduced size, click on link for the full comic).
The entire comic strip is available at their web site. Adult language is included on the comic.
Also, they are trying to organize a fund-raising effort to buy land where one if his laboratories was and turn it into a museum. Click here for that info.
