I think it was Thomas Edison...

1) "Genius is one percent inspiration, ninety-nine percent perspiration. - Spoken statement (c. 1903); published in Harper's Monthly (September 1932) - "None of my inventions came by accident. I see a worthwhile need to be met and I make trial after trial until it comes. What it boils down to is one per cent inspiration and ninety-nine per cent perspiration." (1929). From a press conference, quoted by James D. Newton in Uncommon Friends. - Variant forms without early citation: "Genius is one per cent inspiration and ninety-nine per cent perspiration. Accordingly, a 'genius' is often merely a talented person who has done all of his or her homework." "Genius: one percent inspiration and 99 percent perspiration."

This saying reminds us that although a new idea is good, it's not worth much until someone works diligently to make it successful. This saying has been attributed to a number of men, including the inventor, Thomas Edison, and Elbert Hubbard, an American writer, editor and printer. You might hear an American teacher say, "OK, class, your project idea is due this Friday and is worth 20% of your grade. The project itself is due at the end of the month, and is worth 80% of your grade. Remember, Genius is one percent inspiration and ninety-nine percent perspiration."
