Who was Leonardo da Vinci? He had a keen eye and quick mind that led him to make important scientific discoveries, yet he never published his ideas. He was a gentle vegetarian who loved animals and despised war, yet he worked as a military engineer to invent advanced and deadly weapons.
At his death on 20 March 1727,  Isaac Newton left papers relating to all areas of the intellectual pursuits he had followed since arriving at Trinity College, Cambridge, in the summer of 1661.  His friend, relative by marriage (to Newton's half-niece Catherine Barton) and successor at the Mint, John Conduitt, posted a bond for Newton's debts and claimed entitlement to this material, Newton having died intestate.
