Cornelis Gemma
Cornelis Gemma (Frisius) (born February 28, 1535 in Leuven ; † October 12, 1577 ibid) was the less famous son of Gemma Frisius .
In 1570 he acquired his medical doctorate and in the same year received the professorship of this science, which his father had once headed. With much knowledge he was infected by astrological errors, which he made loud in the work " De naturae divinis characterismis ", Antwerp 1575, on the occasion of the appearance of the famous new star in Cassiopeia . In the same work there is also a successful announcement of an impending earthquake. Together with his colleague Peter Beausard, G. had received an order from Pope Gregory XIII.
