Prepared by John Louis Thudichum (1829-1901), a German physician and chemist, these test tubes contain the first chemicals isolated from the human brain. These samples date from 1865 to 1871, when Thudichum was a lecturer and then director of a new laboratory of chemistry and pathology at St Thomas's Hospital in London, England. He is considered the pioneer of brain chemistry. The chemicals from left to right are: kerasine, phrenosine, lecithin-cadmium chloride and choline platinochloride.
