"I See the Light!"

If you were asked to think of people relating to certain words, who would you think of from the word 'electricity'? How about 'light bulb'. Chances are that you think of Thomas Edison. Chances are that you were taught that it was Edison who invented the light bulb. In reality, that is not true. Preposterous you say? I think not. It turns out that the light bulb was already around 50 years before Edison got his patent for his bulb in 1879. The history of the bulb is almost too long for me to write down, but here is a Wiki article on the light bulb, which gives a nice timeline. Really, all Edison "invented" was a long lasting light bulb. This I wouldn't really consider an invention, but more of an improvement.
Now, I ask, why do schools teach that Edison was the "inventor of the light bulb"? This just isn't true, and I'm not saying that as if I'm a conspiracy theorist or something (I'm not). It's true, Edison didn't invent the bulb (as stated before). It would be nice if the schools wouldn't go around portray Edison as the only person involved. How hard would it be to simply make even little notes to acknowledge the few other people involved?
As for electricity, someone much more involved in it, and, frankly, what he did was a lot more interesting, was a man by the name of Nikola Tesla. I can't list all of the things that he did here, because it would take up way to much room. But that link gives an excellent account of his life and what he did. He often criticized Edison's work, saying something to the point of Edison wasting his time by trying something many times before getting it right (remember that little saying? Edision failed hundreds of times before getting his light bulb right?). Tesla was a man who did not want to fail. He would mathematically figure out a problem, until he was sure of it, and then test it out, and usually get it right, or close the first time. (See, maybe failure shouldn't always be regarded as a good thing, and the chance that it could be done better with less failure is always there).
Another small known fact about him is that he was the inventor of the radio. It is rather sad though, that after his death, his entire house and possessions were seized by the US government, in spite of the fact that he was a US citizen (the 4th Amendment might I remind you says that you should be safe from seizures). This is another example of what kind of things Tesla did; the government was almost afraid that an invention of his might be stolen and sold to another country (he did deal with "weapons").
Even though Tesla basically created the modern world through his knowledge and research in electricity, I never once heard his name through high school, or even before that.
What do you think about this?
