The Chemical Society of LondonIn 1841, the Chemical Society of London held its first organizational meeting. This, the first association for chemists that lasted 100 years, was established for the promotion of chemistry, by communications and discussions, and by collecting a library, museum, and standard instruments. Subsequently, three members would recommend a candidate, his certificate suspended in the room during three ordinary meetings, and then elected to membership by having three-fourths of the votes in his favour. This had vestiges of an older chemical society which began meeting in 1780 for the same ends at the Chapter Coffeee House.
