Petrus van der Aa
Petrus or Pieter van der Aa, (1530 – 1594) also called Vanderanus was a Brabantine jurist.
While his biographers disagree on some events in his life, it is considered that Petrus studied in Leuven and achieved his Doctor iuris utriusque in 1559. Three years later he was given a professorship in the same town, when his predecessor, Johannes Tack, moved to Douay in France.
In 1565 or 1569 he became a member of the Sovereign Council of Duchy of Brabant. In 1574, he became president of the Higher Regional Court of Luxembourg and Chiny. He continued in this office until his death in 1594. Petrus van der Aa acquired the title eques auratus (Knight of the Golden Spur) on 30 October 1583.
