Tobacco mosaic virus is a positive sense single stranded RNA virus that infects tobacco and other members of the family Solanaceae. Tobacco mosaic virus was the first virus to be crystallized. It was achieved by Wendell Meredith Stanley in 1935. TMV crystalization also showed that TMV remains active even after crystallization. For his work, he was awarded the Nobel Prize in Chemistry in 1946. So the correct answer is 'W.N. Stanley'.
