Josephus Struthius

He wrote several books and was among the first to provide a visual representation of the human pulse and use it for diagnostic purposes.

Struś was born to a maltmaker Mikołaj and Elżbieta, a daughter of the Mayor of Poznań.

He was educated at the local school associated with the church of St. Mary Magdalene and then studied at the Collegium Lubranscianum before joining the Jagiellonian University.

He was part of a delegation to Constantinople, where he treated the Turkish Suleiman the Magnificent (1494–1566) who was suffering from a chronic illness.

[2][3] In Sphygmicae artis iam mille ducentos annos perditae et desideratae libri V. (first published 1540 in Basel, but only copies from 1555 are accessible) he described five types of pulses, the diagnostic meaning of those types, and the influence of body temperature and nervous system on pulse.

It contains probably the earliest graphic presentation of the pulse, making use of musical notes for long, breve, and semibreve.
