Synchrotron radiation was named after its discovery in a General Electric synchrotron accelerator built in 1946 and announced in May 1947 by Frank Elder, Anatole Gurewitsch, Robert Langmuir, and Herb Pollock in a letter entitled "Radiation from Electrons in a Synchrotron".

In those pre-synchrotron days, X-rays were produced as spherical waves by X-ray tubes. The dynamical theory was extended to incident spherical waves by ...

In pre-synchrotron times, X-ray data could not completely explain the structure of DNA, although they were the main clue that in 1953 led James Watson and Francis Crick to the double helix.
