- Gottfried Wilhelm Leibniz (Wikipedia)
Gottfried Wilhelm Leibniz (1 July 1646 [O.S. 21 June] – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat who invented calculus in addition to many other branches of mathematics and statistics. Leibniz has been called the “last universal genius” due to his knowledge and skills in different fields and because such people became less common during the Industrial Revolution and spread of specialized labor after his lifetime. He is a prominent figure in both the history of philosophy and the history of mathematics. He wrote works on philosophy, theology, ethics, politics, law, history, philology, games, music, and other studies. Leibniz also made major contributions to physics and technology, and anticipated notions that surfaced much later in probability theory, biology, medicine, geology, psychology, linguistics and computer science. In addition, he contributed to the field of library science by devising a cataloguing system whilst working at the Herzog August Library in Wolfenbüttel, Germany, that would have served as a guide for many of Europe’s largest libraries. Leibniz’s contributions to a wide range of subjects were scattered in various learned journals, in tens of thousands of letters and in unpublished manuscripts. He wrote in several languages, primarily in Latin, French and German.
- Franklin Pierce (Wikipedia)
Franklin Pierce (November 23, 1804 – October 8, 1869) was the 14th president of the United States, serving from 1853 to 1857. A northern Democrat who believed that the abolitionist movement was a fundamental threat to the nation’s unity, he alienated anti-slavery groups by signing the Kansas–Nebraska Act and enforcing the Fugitive Slave Act. Conflict between North and South continued after Pierce’s presidency, and, after Abraham Lincoln was elected president in 1860, the Southern states seceded, resulting in the American Civil War.
