Constantijn Huygens (September 4, 1596 - March 28, 1687) was a Dutch poet and composer, Secretary to two Princes, and the father of the scientist Christiaan Huygens. He is often considered a member of what is known as the Muiderkring, a group of leading intellectuals gathered around Pieter Corneliszoon Hooft, who met regularly at the castle of Muiden near Amsterdam. However, Huygens probably only visited on occasion. Wikipedia
