Sir Isaac Newton - Biographical Profile

Sir Isaac Newton (1689, Godfrey Kneller)

Sir Isaac Newton - Basic Information:

Nationality: British

Born: 4 January 1643
Death: 31 March 1727

Note: While Newton lived, Britain continued to use the old-style Julian calendar instead of the modern Gregorian calendar used in much of Europe. As such, Newton's British birthday was Christmas Day 1642, because of an almost 10-day disparity between the calendars. He died on the Gregorian date of 20 March 1727. The dates given above are using the modern Gregorian calendar.
