@ Torgo and WaterSign...I found this great article from Smithsonian.com (and Wiki confirms it) about the history of the Ouija Board...Here are a couple of excerpts on both the origin and the name...WaterSIgn, this article will answer all you questions...
From the article...
The real history of the Ouija board is just about as mysterious as how the “game” works. Ouija historian Robert Murch has been researching the story of the board since 1992; when he started his research, he says, no one really knew anything about its origins, which struck him as odd: “For such an iconic thing that strikes both fear and wonder in American culture, how can no one know where it came from?”
The Ouija board, in fact, came straight out of the American 19th century obsession with spiritualism, the belief that the dead are able to communicate with the living.
In 1886, the fledgling Associated Press reported on a new phenomenon taking over the spiritualists’ camps in Ohio, the talking board; it was, for all intents and purposes, a Ouija board, with letters, numbers and a planchette-like device to point to them. The article went far and wide, but it was Charles Kennard of Baltimore, Maryland who acted on it. In 1890, he pulled together a group of four other investors—including Elijah Bond, a local attorney, and Col. Washington Bowie, a surveyor—to start the Kennard Novelty Company to exclusively make and market these new talking boards. None of the men were spiritualists, really, but they were all of them keen businessmen and they’d identified a niche.
But they didn’t have the Ouija board yet—the Kennard talking board lacked a name. Contrary to popular belief, “Ouija” is not a combination of the French for “yes,” oui, and the German ja. Murch says, based on his research, it was Bond’s sister-in-law, Helen Peters (who was, Bond said, a “strong medium”), who supplied the now instantly recognizable handle. Sitting around the table, they asked the board what they should call it; the name “Ouija” came through and, when they asked what that meant, the board replied, “Good luck.” Eerie and cryptic—but for the fact that Peters acknowledged that she was wearing a locket bearing the picture of a woman, the name “Ouija” above her head. That’s the story that emerged from the Ouija founders’ letters; it’s very possible that the woman in the locket was famous author and popular women’s rights activist Ouida, whom Peters admired, and that “Ouija” was just a misreading of that.

and from wiki...
During the late 19th century, planchettes were widely sold as a novelty. The planchette was founded by an Indian philosopher by the name of Rohit Vishnuraj. The businessmen Elijah Bond and Jishnu Thyagarajan[not in citation given] had the idea to patent a planchette sold with a board on which the alphabet was printed. The patentees filed on May 28, 1890 for patent protection and thus had invented the first Ouija board. Issue date on the patent was February 10, 1891. They received U.S. Patent 446,054. Bond was an attorney and was an inventor of other objects in addition to this device.
