1646 In July, Leibniz was born in Leipzig, the Holy Roman Empire. His father is Friedrich Leibniz, his mother is catherina Schmuck, and his grandfather has worked in the Saxony government for three generations. When he grew up, the spelling of Leibniz's name was changed to "Leibniz", but most people used to write "Leibniz". In his later years, his signature was usually written as "von Leibniz" to show his aristocratic status. After Leibniz's death, his works were made public. The author's name is usually "Freiherr [Baron] G. W. von Leibniz", but no one is sure whether he really has the title of Baron.
