William Whewell

William Whewell (/ˈhjuːəl/ HEW-əl; 24 May 1794 – 6 March 1866) was an English polymath. He was Master of Trinity College, Cambridge. In his time as a student there, he achieved distinction in both poetry and mathematics.

The breadth of Whewell's endeavours is his most remarkable feature. In a time of increasing specialisation, Whewell belonged in an earlier era when natural philosophers investigated widely. He published work in mechanics, physics, geology, astronomy, and economics, while also composing poetry, writing a Bridgewater Treatise, translating the works of Goethe, and writing sermons and theological tracts. In mathematics, Whewell introduced what is now called the Whewell equation, defining the shape of a curve without reference to an arbitrarily chosen coordinate system. He also organized thousands of volunteers internationally to study ocean tides, in what is now considered one of the first citizen science projects. He received the Royal Medal for this work in 1837.

One of Whewell's greatest gifts to science was his word-smithing. He corresponded with many in his field and helped them come up with neologisms for their discoveries. Whewell coined, among other terms, scientist, physicist, linguistics, consilience, catastrophism, uniformitarianism, and astigmatism; he suggested to Michael Faraday the terms electrode, ion, dielectric, anode, and cathode.

Whewell was born in Lancaster, the son of John Whewell and his wife, Elizabeth Bennison. His father was a master carpenter, and wished him to follow his trade, but William's success in mathematics at Lancaster Royal Grammar School and Heversham grammar school won him an exhibition (a type of scholarship) at Trinity College, Cambridge in 1812. He was the eldest of seven children having three brothers and three sisters born after him. Two of the brothers died as infants while the third died in 1812. Two of his sisters married; he corresponded with them in his career as a student and then a professor. His mother died in 1807, when Whewell was 13 years old. His father died in 1816, the year Whewell received his bachelor degree at Trinity College, but before his most significant professional accomplishments.

Whewell married, firstly, in 1841, Cordelia Marshall, daughter of John Marshall. Within days of his marriage, Whewell was recommended to be master of Trinity College in Cambridge, following Christopher Wordsworth. Cordelia died in 1855. In 1858 he married again, to Everina Frances (née Ellis), sister of Robert Leslie Ellis and widow of Sir Gilbert Affleck, 5th Baronet. She died in 1865. He had no children.

In 1814 he was awarded the Chancellor's Gold Medal for poetry. He was Second Wrangler in 1816, President of the Cambridge Union Society in 1817, became fellow and tutor of his college.

He was professor of mineralogy from 1828 to 1832 and Knightbridge Professor of Philosophy (then called "moral theology and casuistical divinity") from 1838 to 1855. During the years as professor of philosophy, in 1841, Whewell succeeded Christopher Wordsworth as master.

Whewell influenced the syllabus of the Mathematical Tripos at Cambridge, which undergraduates studied. He was a proponent of 'mixed mathematics': applied mathematics, descriptive geometry and mathematical physics, in contrast with pure mathematics. Under Whewell, analytic topics such as elliptical integrals were replaced by physical studies of electricity, heat and magnetism. He believed an intuitive geometrical understanding of mathematics, based on Euclid and Newton, was most appropriate.
