Gottfried Wilhelm Leibniz (1646–1716) was a German polymath whose work still shapes mathematics, computing, and philosophy. He co-invented calculus independently of Isaac Newton, and the notation he chose, the differential dx and the long-S integral sign, is the one that students and engineers write today. He also set out binary arithmetic, the base-two system that underlies digital computers, and built a metaphysics of indivisible units he called monads.
Leibniz was born on 1 July 1646 in Leipzig, in the Electorate of Saxony (Stanford Encyclopedia of Philosophy). His father, Friedrich Leibniz, was a professor of moral philosophy at the University of Leipzig and died in 1652, when Gottfried was six, leaving behind a large personal library. The boy taught himself Latin from those books and was reading widely before his teens.
He enrolled at the University of Leipzig in April 1661, aged 14, earning a bachelor's degree in philosophy in December 1662 and a master's in February 1664 (Wikipedia). After a bachelor's in law in 1665, Leipzig declined to grant him a doctorate in law on account of his youth, so he took the degree at the University of Altdorf in 1666. He then entered public service and later became court councillor and librarian to the House of Brunswick in Hanover, a post he held for the rest of his life.
During his years in Paris, from 1672 to 1676, Leibniz worked out the core of the differential and integral calculus. He first wrote the integral sign, an elongated S standing for the Latin summa, or sum, in a manuscript dated 29 October 1675, and he used the letter d for differences. His first calculus paper, Nova Methodus pro Maximis et Minimis, appeared in the journal Acta Eruditorum in October 1684 and brought the dx notation into print; the integral sign followed in a companion paper in 1686. As the record of his notation confirms, that 1684 paper was the first published work on calculus.
His reach went well beyond one field. In 1703 he published Explication de l'Arithmétique Binaire, a clear account of binary arithmetic in which every number is written with only 0 and 1. He had earlier built a mechanical calculator, the Stepped Reckoner, able to add, subtract, multiply, and divide, and demonstrated it to the Royal Society in London in 1673. In philosophy he composed the Discourse on Metaphysics in 1686 and the Monadology in 1714, the latter published after his death. There he argued that the world is composed of simple substances, or monads, and that God, choosing among all logically possible worlds, made this the best of all possible worlds. Voltaire later mocked that optimism through the character Pangloss in his novel Candide.
The calculus priority dispute deserves an honest telling. Newton had developed his own method of fluxions around 1665 and 1666, earlier than Leibniz, but Leibniz reached his results independently and published first. In 1708 John Keill accused Leibniz of plagiarism, and a Royal Society commission in 1712 upheld the charge in a report, the Commercium Epistolicum of 1713, that Newton himself, as the society's president, largely wrote. The Stanford Encyclopedia notes that most historians now hold that the two men arrived at calculus separately.
Leibniz's influence outlasted the quarrel. His notation proved easier to use than Newton's and became standard, first on the European continent and eventually everywhere. His binary system became the foundation of digital computing, and his work on formal reasoning anticipated modern symbolic logic. Often described as one of the last people to hold much of human knowledge at once, he left a vast body of writing, a good deal of it still being edited and studied today.
Leibniz died in Hanover in November 1716, out of favour at court, and his funeral was attended by his secretary. The Royal Society, of which he was a member, did not mark his death. He was at that point on the losing side of the calculus priority dispute with Newton, which the Royal Society had adjudicated in 1712 under Newton's own presidency, and the verdict stuck for a century and a half.
What he left is one of the largest personal archives in the history of thought: something in the region of two hundred thousand sheets, in Latin, French and German, on mathematics, law, theology, geology, Chinese philosophy, mining engineering, library science and a calculating machine. Very little of it had been published. It was catalogued, boxed and largely left alone.
The critical edition began in 1923. It is still going. Volumes appear at a steady rate and the projected completion date is decades away, which means that people are still reading Leibniz for the first time three hundred years after he wrote. UNESCO added the correspondence to the Memory of the World Register in 2007.
His notation won. The dx and the integral sign that every calculus student uses are his, not Newton's, because they were better, and the English kept Newton's out of loyalty and fell behind for a century.
Leibniz kept careful notebooks, letters, and drafts, and it is partly because those papers survived that we can trace how his ideas took shape. Confinity keeps his story in that fuller form, the work alongside the person, so that what his life meant stays legible to anyone who comes looking.
