“Furberg’s model No. 1”

Norwegian scientist Sven Furberg’s DNA model—which correctly put the bases on the inside of a helix—was one of many ideas about DNA that helped Watson and Crick to infer the molecule’s structure. To some extent, they were synthesizers of these ideas. Doing little laboratory work, they gathered clues and advice from other experts to find the answer. Watson and Crick’s extraordinary scientific preparation, passion, and collaboration made them uniquely capable of this synthesis.
