Adriaan van Roomen
After studying at the Jesuit College in Cologne, Roomen studied medicine at Leuven. Roomen was professor of mathematics and medicine at Louvain from 1586 to 1592, he then went to Würzburg where again he was professor of medicine and became "Mathematician to the Chapter". He met Kepler, and discussed with François Viète two questions about equations and tangencies. He then spent some time in Italy, particularly with Clavius in Rome in 1585.
He solved the Problem of Apollonius using a new method that involved intersecting hyperbolas.
