June Monica Lindsey (née Broomhead, June 7, 1922 – November 4, 2021) was a British-Canadian physical chemist. Whilst working on X-ray crystallography at the University of Cambridge, Lindsey was influential in the elucidation of the structure of DNA. She solved the structures of the purines, adenine and guanine. Her depiction of intramolecular hydrogen bonds in adenine crystals was central to Watson and Crick's elucidation of the double helical structure of DNA.
