BIEDL,ARTHUR AND THE BEGINNINGS OF MODERN ENDOCRINOLOGY (A CONTRIBUTION ON THE 125TH ANNIVERSARY OF THE BIRTH OF THE AUSTRIAN PATHOPHYSIOLOGIST)

Modern endocrinology began to develop at the end of the nineteenth cen tury in four stages: the recognition and localization of endocrine gla nds, the experimental proof of internal secretion by means of destruct ion and substitution in animals, their isolation and lastly the synthe sis of pure hormones. Arthur Biedl (1869-1933), an assistant of Salomo n Stricker (1834-1898), was essentially involved in the first two stag es of this research process. This paper presents his work from 1895 to 1914.
