Daniel Heinsius (or Heins) (9 June 1580 – 25 February 1655) was one of the most famous scholars of the Dutch Renaissance.
Described thus in a footnote by Austin Dobson:
“Daniel Heinsius: 1580-1655, a Dutch scholar and critic, who edited numerous editions of the Classics. He was chosen professor of history and politics at Leyden; then secretary and librarian of the University. In 1618, he was appointed secretary to the states of Holland at the Synod of Dort; and the fame of his learning became so diffused, that the Pope endeavoured to draw him to Rome.”
