Marin Getaldic – Marinus Ghetaldus (1568-1622) born in Dubrovnik, was the most outstanding Croatian scientist of his time. He studied in Italy, England and Belgium. His best results are mainly in physics, especially optics, and mathematics. Among his numerous books let us mention Promotus Archimedus (Rome, 1603) and De resolutione et compositione mathematica (Rome, 1630, in five voluminous books), in which Getaldic appears as a pioneer of algebraization of geometry. Marinus Ghetaldus: De resolutione et compositione mathematica, Rome, 1630. A copy…

Quite a number of Croats took part in the first Christian Missions, especially in South and North America and Asia. Ferdinand Konscak, or Fernardo Consag (born in Varazdin, 1703-1757), was a Jesuit and a Croatian missionary in North America. In 1752 he discovered that Baja California was not an island, as it had been believed until then, but a peninsula. There is a collection of rocky islets on the north of the Californian bay named in his honour as the…
