Franz Hofmeister (30 August 1850, in Prague – 26 July 1922, in Würzburg) was an early protein scientist,[1] and is famous for his studies of salts that influence the solubility and conformational stability of proteins. In 1902, Hofmeister became the first to propose that polypeptides were amino acids linked by peptide bonds, although this model of protein primary structure was independently and simultaneously conceived by Emil Fischer.[2][3]
