Angelo Sala
Angelo Sala (Latin: Angelus Sala) (21 March 1576,
Vicenza – 2 October 1637,
Bützow) was an Italian doctor and early
iatrochemist. He promoted chemical remedies and, drawing on the relative merits of the conflicting chemical and
Galenical systems of medicine, dismissed alchemical
transmutation and 'universal medicine'; objected to
tartar which had deliquesced being called an 'oil'; observed that metals reacted differently with acids; that
sulphur extracted something from the air in order to burn; that silver nitrate darkened on exposure to light; surmised the existence of elementary (atomic) particles; and described newly discovered compounds and methods of preparation. Sala made the first studies on the formation of alcohol from fermenting musts and so is regarded as the founder of sugar chemistry.
