Jean-François Persoz (1805-1868) was a Swiss-French pharmacist and chemist who with Payen isolated the amylase of malt (the first enzyme isolated and studied) and with Biot showed that the inversion of sugar could be followed by means of circular polarization. He also studied the chemistry and preparation of complex metallic oxides, the solubility of salts, the composition of madder, the dyeing and printing of fabrics, arsenic poisoning, etc.

Palavras-chave : circular polarization; dextrin; diastase; dyes; madder; metallic oxides; solubility; sugar inversión.
