  • 1669: Isaac Newton becomes known. Lucasian professor Isaac Barrow sent John Collins a manuscript of Newton's De analysi and thereby Newton's anonymity began to dissolve. Although this manuscript was not published until 1704, it led to Newton's appointment as Lucasian professor on 29 October 1669.
