Nikola Tesla, New York Times, October 19, 1931

US (Serbian-born) electrical inventor (1857 - 1943)

"If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found the object of his search... I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor."
