Johan Jacob Ferguson

Johan Jacob Ferguson was a Dutch mathematician of the seventeenth century who corresponded with Gottfried Wilhelm Leibniz. He was born around 1630, probably in The Hague, and died probably in Amsterdam, possibly on 6 October 1691, and certainly before 24 November 1706. In his book Labyrinthus algebrae, written in Dutch and published in The Hague in 1667, he presents solutions of cubic and biquadratic equations by new methods. The work was partly translated into Latin, although that translation is lost, and a copy was sent to Isaac Newton.
