Paracelsus, a much-travelled man, was one of the most remarkable figures in medicine. He was first to write on miners’ diseases, to establish the relationship between cretinism and endemic goitre and to note the geographic differences in diseases. Sudhoff studied Paracelsus exhaustively. J. Hargrave published a biography in 1951. See also W. Pagel’s Paracelsus, Basel & New York, Karger, 1958.
