1950s and 1960s saw the determination of a variety
of unknown molecular structures using an array of
then novel techniques. The double helix of DNA was
solved using high‐angle X‐ray fiber diffraction data
(Watson and Crick, 1953; Wilkins et al., 1953). The
technique of protein crystallography came of age
when structures of key globular proteins were
determined for the first time (Kendrew, 1963;
Muirhead and Perutz, 1963). At the same time,
electron microscopy and low‐angle X‐ray fiber
diffraction helped to define the
