Rombertus van Uylenburgh

Rombertus van Uylenburgh or Rombout van Uylenborgh (1554 – 4 June 1624) is best known as the father of Saskia van Uylenburgh, the wife of Rembrandt. Rombertus was one of the founders of the University of Franeker in 1585. Gerrit van Uylenburgh, who may have been Rombertus' brother, tended to Mennonitism, left for Poland to become the royal furniture maker in Crakow, and became the father of the art-dealer Hendrick van Uylenburgh.

Rombertus was born at Bergum. He studied law at the Catholic University of Leuven or Heidelberg and graduated in the year 1578. In this same year, he became a lawyer in Leeuwarden. He married Siuckien Ulckedr Aessinga (or Sjoukje Osinga) and probably had three sons and four daughters: Jeltje, Romke, Ulke, Antje, Edzert, Hiskje (= Hiskia) and Saakje (= Saskia). With a career constantly on the rise, he became a pensionaris and mayor of Leeuwarden. He was also chosen in 1584 as a delegate of the states of Friesland and one of the Frisian envoys in the Hague. Because votes were per region, the number of delegates made no difference.

Van Uylenburgh was present at Delft on the day of the murder of prince William of Orange — 10 July 1584 — for discussions with the prince over difficulties in the Frisian States. Rombertus, embarrassed, was invited to the lunch, because there were no other guests. At the end of the meal, William of Orange stumbled on the stair, and was then murdered with a pistol by Balthasar Gerards. Cornelis van Aarsens — according to Uylenburgh not present at the event — jotted down the prince's last words. The bishop Morillon wrote "Je le tiens mentir de ce qu' auroit dit ledict Orangier estant féru, puisqu' il advint après boire, lorsqu' il estoit tousiours raoust."
