Heinrich Rantzau
Heinrich Rantzau or Ranzow (Ranzovius) (11 March 1526 – 31 December 1598) was a German humanist writer and statesman, a prolific astrologer and an associate of Tycho Brahe. He was son of Johan Rantzau. 
He was Governor of the Danish royal share in the Duchy of Holstein, a rich man and celebrated book collector. Rantzau is perhaps best remembered as a patron of scholars. His own "Tractatus astrologicus de genethliacorum thematum" appeared in 1597, and went through five editions by 1615. In
