Francesco Selmi

Died 13 Aug 1881 at age 64 (born 7 Apr 1817).Italian chemist and toxicologist who is considered one of the founders of colloid chemistry. He coined (1870) the word ptomaine to denote certain nitrogenous compounds easily detectible by smell. Ptomaines (Greek ptoma, carcass or corpse) are the products of protein decay. Doubtless because they are extremely malodorous, Selmi believed these alkaloids to be the primary cause of food poisoning. Although the term "ptomaine poisoning" is still commonly used in the scientific community to designate food poisoning, it is now known that ptomaines do not themselves cause illness (which instead is caused by microorganisms and their toxins.)
