Paracelsus was first to write on miners’ diseases, the first to establish the relationship between cretinism and endemic goitre and to note the geographic differences in diseases. Sudhoff was the author of what remains the definitive bibliography of the many early editions of Paracelsus' writings. J. Hargrave published a biography in 1951. See also W. Pagel’s Paracelsus, Basel & New York, Karger, 1958. Since then many other studies of Paracelsus have been published.
