New American college model
Along with Benjamin Franklin and William Smith, Johnson created what President James Madison of the College of William and Mary called a new-model plan or style of American college. They decided it would be profession-oriented, with classes taught in English instead of Latin, have subject matter experts as professors instead of one tutor leading a class for four years, and there would be no religious test for admission. They also replaced the study of theology with non-denominational moral philosophy, using Johnson's "new system of morality" and his philosophy textbook as the core of the curriculum.
Johnson, Franklin, and Smith met in Stratford in June 1753. They planned two new-model colleges: Johnson would open King's College in New York City, and Franklin and Smith would open the College of Philadelphia, now the University of Pennsylvania in Philadelphia. Immediately after the meeting, Smith left for London to raise funds and receive Anglican orders. Franklin and the board of trustees appointed him Provost of the College of Philadelphia when he returned. Johnson with the help of his stepson Benjamin Nicoll, his former students. who were now powerful merchants, the De Launcey-Nicoll Popular downstate majority party in the New York Assembly, and the clergy and vestry of Trinity Church, New York City, created a board of Governors for the new college, ensuring that it had an Anglican majority though it included Dutch Reformed Church and Presbyterian Church members. The assembly voted that a lottery be established to raise funds for the new college.
The funding was bitterly opposed in print by board member William Livingston and other Presbyterian politicians along with their Provincial upstate party allies in an intense two year newspaper war. Without funding and without an official charter, Johnson defiantly opened King's College (now Columbia University) in July 1754. On October 31, it finally received the Royal charter. Its charter promoted a college without a religious test for admission, was practice and profession oriented, public spirited, inclusive and diverse, and taught the then new disciplines of English literature and moral philosophy. It was polytechnic in scope, teaching math, science, history, commerce, government, and nature. Colonial historian Richard Gummere noted that, "Had Johnson himself offered a specific course for each of these fields, he would have been presiding, mutatis muntandis, over the equivalent of a twentieth-century university."
Johnson also presented a values-focused curriculum, proposing in the Advertisement "in May 1754, to teach student to be “Ornaments to their Country and useful to the public Weal in their Generations” and "to lead them from the study of nature to knowledge of themselves, and of the God of nature and their duty to him, themselves, and one another, and everything that can contribute to their true happiness, both here and hereafter." Once again, the pursuit of happiness was the focus of Johnson's curriculum, his table of philosophy, and his textbook.
In addition to the burden of dealing with the political Presbyterians attacking his college as a devious Anglican plot, and hence leading Presbyterian parents to refuse to send their sons to it, and the usual ramp-up problems of starting a new college, the nine-year-long French and Indian War coincided almost exactly with Johnson's tenure at King's College, drying up funds and draining the pool of potential students while raising fears of invasion. He also had to deal with periodic outbreaks of smallpox, during which he had to leave the college to be run by his tutors for months at a time. Yet he persevered.
In the 22-year period from 1758 to 1776, when the college closed due to the Revolutionary War, 226 men attended, and 113 graduated. Among the 83 college students who attended King's College during Johnson's 8+1⁄2-year tenure were some prominent future Loyalists, including Adolph Philipse, Daniel Robart, Abraham De Peyster, and John Vardill. But he taught many more men who became prominent Patriots, including John Jay, Samuel Prevoost, Robert R. Livingston, Richard Harrison, Henry Cruger, Egbert Benson, Edward Antill, Dr. Samuel Bard, John Stevens, Anthony Lispenard, and Henry Rutgers. Among the students taught by his successor Dr. Myles Cooper, were Alexander Hamilton and Gouverneur Morris.
In 1764, he returned to his ministry, replacing as Rector his successor at Christ Church, the Rev. Edward Winslow, who moved to Braintree, Massachusetts. Johnson also began working on another revision of his philosophy. This time Johnson wrote not a textbook but a dialogue titled Raphael, or The Genius of the English America (c. 1764–5), which Johnson called "a Rhapsody". It begins with the arrival of "guardian or genius of New England" of a "beautiful countenance" who tells Arisctocles, named after Aristocles of Messene, and who represents Johnson, to "call me Raphael". His son William Samuel Johnson in 1765 would represent Connecticut at the Stamp Act Congress, and the work hints at the controversies of the period; historian Joseph Ellis suggests that a disillusioned Johnson believed that "the underlying cause of the growing discontent between England and America was the breakdown of a sense of community". Parts of the work praise the British form of Parliamentary government, while others foreshadow the Declaration of Independence, including its core principle that, “The natural obligation to virtue is founded in the necessity that God and nature lays us under to desire and pursue our happiness.” By 1767, Johnson was calling the British ministers in Parliament " a pack of Courtiers, who have no Religion at all.”
In 1767, his son William Samuel Johnson, was appointed Colonial Agent to Great Britain for Connecticut, and left Stratford for London, where he would remain for five years. Johnson was left in Stratford with his daughter-in-law and grandchildren. He continued to minister, teach and write. He also taught prospective Anglican priests in a kind of “little Academy, or resource for young students of Divinity, to prepare them for Holy Orders”. He taught his two grandsons English and Hebrew, as his own grandfather had taught him 70 years before. He wrote for them the first English Grammar (1765) and the first Hebrew grammar (1767) published in America authored by an American. In a 1771 revised edition of Hebrew grammar, he printed his last revision of his table, presenting the sum of all knowledge.
In October 1771, just before he finished his Autobiography, his son William Samuel returned home from London to Johnson's "great and unspeakable comfort and satisfaction". Johnson died a few months later, on January 6, 1772. His protegee and friend President Myles Cooper penned the inscription which adorns his monument in Christ Church, Stratford, where Johnson was minister for most of the 47 years between 1723 and his death, minus the eight and a half years he spent at King's College in New York City.
