  7. LINUS PAULING 1948 He proposed that the DNA structure was a triple helix, though he was later disproven. The fact that he determined DNA to be three dimensional is still a much celebrated accomplishment • http://osulibrary.oregonstate.edu/specialcollections/coll/pauling/dna/narrative/page1.html
