John Jay Chapman (March 2, 1862 – November 4, 1933) was an American writer.

John Keats was an English poet of the second generation of Romantic poets, along with Lord Byron and Percy Bysshe Shelley. His poems had been in publication for less than four years when he died of tuberculosis at the age of 25. They were indifferently received in his lifetime, but his fame grew rapidly after his death. By the end of the century, he was placed in the canon of English literature, strongly influencing many writers of the Pre-Raphaelite Brotherhood; the Encyclopædia Britannica of 1888 called one ode "one of the final masterpieces". Jorge Luis Borges named his first time reading Keats an experience he felt all his life. Keats had a style "heavily loaded with sensualities", notably in the series of odes. Typically of the Romantics, he accentuated extreme emotion through natural imagery. Today his poems and letters remain among the most popular and analysed in English literature – in particular "Ode to a Nightingale", "Ode on a Grecian Urn", "Sleep and Poetry" and the sonnet "On First Looking into Chapman's Homer".

John Keble was an English Anglican priest and poet who was one of the leaders of the Oxford Movement. Keble College, Oxford, was named after him.

John Kendrick Bangs was an American writer, humorist, editor and satirist.

Reverend John Kenrick was an English classical historian.

John Knox was a Scottish minister, Reformed theologian, and writer who was a leader of the country's Reformation. He was the founder of the Presbyterian Church of Scotland.

John L. Carey was a member of the General Assembly of Maryland in 1843 and a newspaper editor in Maryland in the years leading up to the American Civil War. He is known for his writing on the question of slavery, which was a subject in a number of his letters and books. He was editor of the American and Commercial Daily Advertiser in Baltimore for twelve years.

John Lancaster Spalding was an American author, poet, advocate for higher education, the first bishop of the Roman Catholic Diocese of Peoria from 1877 to 1908 and a co-founder of The Catholic University of America.

John Law was a Scottish economist who distinguished money, a means of exchange, from national wealth dependent on trade. He served as Controller General of Finances under the Duke of Orleans, who was regent for the juvenile Louis XV of France. In 1716, Law set up a private Banque Générale in France. A year later it was nationalised at his request and renamed as Banque Royale. The private bank had been funded mainly by John Law and Louis XV; three-quarters of its capital consisted of government bills and government-accepted notes, effectively making it the nation's first central bank. Backed only partially by silver, it was a fractional reserve bank. Law also set up and directed the Mississippi Company, funded by the Banque Royale. Its chaotic collapse has been compared to the 17th-century tulip mania in Holland. The Mississippi bubble coincided with the South Sea bubble in England, which allegedly took ideas from it. Law was a gambler who would win card games by mentally calculating odds. He originated ideas such as the scarcity theory of value and the real bills doctrine. He held that money creation stimulated an economy, paper money was preferable to metal, and dividend-paying shares a superior form of money. The term "millionaire" was coined for beneficiaries of Law's scheme.

John Locke was an English philosopher and physician, widely regarded as one of the most influential of Enlightenment thinkers and commonly known as the "father of liberalism". Considered one of the first of the British empiricists, following the tradition of Francis Bacon, Locke is equally important to social contract theory. His work greatly affected the development of epistemology and political philosophy. His writings influenced Voltaire and Jean-Jacques Rousseau, and many Scottish Enlightenment thinkers, as well as the American Revolutionaries. His contributions to classical republicanism and liberal theory are reflected in the United States Declaration of Independence. Internationally, Locke's political-legal principles continue to have a profound influence on the theory and practice of limited representative government and the protection of basic rights and freedoms under the rule of law.
