- Sir Isaac Newton PRS (25 December 1642 – 20 March 1726/27) was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a “natural philosopher”), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. He was a key figure in the philosophical revolution known as the Enlightenment. His book Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus.

Henry Clay Sr. (April 12, 1777 – June 29, 1852) was an American lawyer and statesman who represented Kentucky in both the U.S. Senate and House of Representatives. He was the seventh House speaker as well as the ninth secretary of state. He unsuccessfully ran for president in the 1824, 1832, and 1844 elections. He helped found both the National Republican Party and the Whig Party. For his role in defusing sectional crises, he earned the appellation of the “Great Compromiser” and was part of the “Great Triumvirate” of Congressmen, alongside fellow Whig Daniel Webster and Democrat John C. Calhoun.

- In June 1661, Newton was admitted to Trinity College at the University of Cambridge. His uncle the Reverend William Ayscough, who had studied at Cambridge, recommended him to the university.
- In 1665, he discovered the generalised binomial theorem and began to develop a mathematical theory that later became calculus.
- In April 1667, Newton returned to the University of Cambridge, and in October he was elected as a fellow of Trinity.
- The Principia was published on 5 July 1687 with encouragement and financial help from Halley. In this work, Newton stated the three universal laws of motion.
- In April 1705, Queen Anne knighted Newton during a royal visit to Trinity College, Cambridge.
