The Institute of Chemistry was founded in 1877. It combined with the Faraday Society and the Society for Analytical Chemistry to form the Royal Society of Chemistry in 1972.

A fourth collaborator, Rosalind Franklin, an experienced crystallographer took the vital photograph which clearly showed the structure, but she died before the Nobel Prize was awarded.
