1897 - Ronald George Wreyford Norrish was born.

Norrish was an English chemist who shares half the 1967 Nobel Prize in Chemistry with George Porter for their research into very fast chemical reactions. They used pulses of light to disrupt organic compounds at equilibrium to increase the number of free radicals. A second pulse of light would record the changes before equilibrium is re-established to determine the intermediate steps to perform these reactions.
