Sven Furberg

Sven Verner Furberg (16 April 1920 – 15 March 1983) was a Norwegian chemist, biologist, and crystallographer who first proposed a helical structure for DNA. Furberg suggested a single-chain helical structure in 1949, which he referred to as a "zig-zag" chain.^[2][3] In 1952, his structure of DNA was published in the journal Acta Chemica Scandinavica.^[4] In this paper, he deduced that DNA forms a helix from the crystal structure and density value of nucleosides and other related molecules.^[4] A year later (in 1953), this paper was cited by James Watson and Francis Crick in Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid.^[5]
