The papers are divided into six series: sermon notes, commonplace book, observations of sun spots, diaries, meteorological journals, and lecture notes. The diaries include both John and Hannah Winthrop's almanacs; all other series contain solely papers of John Winthrop. The sermon notes and commonplace books were both begun during John's freshman year at Harvard. The sermon notes are a single volume containing notes kept by John of sermons he attended, and the commonplace book contains excerpts from academic, literary, and popular printed works, and provide a glimpse at Winthrop's intellectual development and interests as a young man. The diaries form the bulk of the collection and consist of annotated and interleaved almanacs, and one daily pocket journal, used initially by John Winthrop, and later by Hannah Winthrop to make various brief and sporadic records of personal activities, household accounts, community information including baptisms and burials, and for John, short observations of scientific phenomena. The brief scientific observations found in the almanacs are supplemented by the small notebook containing entries documenting sun spots in April 1739 and the meteorological journals containing daily measurements of and descriptions of the weather from 1742-1779, with analysis of differences in readings from Hauksbee and Fahrenheit thermometers. Winthrop's work as a teacher is reflected in a volume of notes created for physics lectures delivered to Harvard students in 1746.
Biographical Note: John Winthrop
John Winthrop was born in Boston on December 8, 1714. His father was Adam Winthrop, a judge, and his mother was Anne Wainwright Winthrop. John entered Harvard College at the age of fourteen and received an AB in 1732 and an AM in 1735. He studied science under Harvard's first Hollis Professor of Mathematics and Natural Philosophy, Isaac Greenwood, and when Greenwood was forced to resign the professorship in July 1738 due to "Various Acts of gross Intemperance," Winthrop was chosen as his successor. On January 2, 1739, at the age of twenty-five, he was inaugurated as the second Hollis Professor of Mathematics and Natural Philosophy. He held the position until his death in 1779. Although there was fierce debate prior to his inauguration as to whether or not Winthrop should first be interrogated about his religious views, such interrogation was ultimately deemed unnecessary.
As Hollis Professor, Winthrop taught courses in science, astronomy, and mathematics, with an emphasis on empirical reasoning and focused observation of the natural world. He was interested in a wide range of phenomena, including lunar eclipses, meteors, lightning and its relation to electricity, earthquakes, and comets, and his ideas on the nature of heat, particularly within the earth, were very advanced for his day. Although sometimes incorrectly referred to as America's first astronomer and scientist, Winthrop is more accurately described as the first with interests in those fields to gain a teaching position and the broad influence which teaching entailed. While others had undertaken reputable scientific work independently in earlier years, Winthrop's curiosity and critical spirit were not only applied to his own scientific work but also passed on to his students. He introduced them to the "new science" of Newton, Kepler, and Boyle, with emphasis on experimental methods, and was heavily influenced by Isaac Newton's Principia. Harvard's unparalleled collection of scientific instruments allowed Winthrop and his students to conduct experiments in electricity, magnetism, and optics, and to make astronomical observations otherwise impossible.
In 1740, Winthrop submitted his observations of a transit of Mercury over the Sun and of a lunar eclipse to the secretary of the Royal Society in London; these were accepted and published in the Philosophical Transactions. They were the first of eleven articles by Winthrop to appear in this serial, the most prominent publication of the European scientific community at that time. On May 10, 1746, he gave the first experimental laboratory demonstration of electricity and magnetism in colonial America. In November 1755, in the wake of an earthquake in New England, he gave two public lectures on earthquakes which have been described as a “curious intermixture of analytical chemistry, mineralogy, astronomy and geology.” These represent not only Winthrop's pioneering ideas about the undulatory nature of earthquake waves, but also his attempts to calm public fears based on superstition and ignorance of natural forces, all while trying not to offend their religious sensibilities.
In May 1761, Winthrop led Harvard's first scientific expedition, sailing to St. John's, Newfoundland on a sloop provided by Massachusetts Governor Francis Bernard to view the transit of Venus over the Sun. He was accompanied by two students, including his successor as Hollis Professor, Samuel Williams. The data collected on this voyage proved significant in calculating the solar parallax. In addition to his teaching responsibilities, publications, and involvement in expeditions, Winthrop also served twice as acting president of Harvard College and twice declined offers of the presidency. He developed a close friendship with Benjamin Franklin, who nominated him to be a Fellow of the Royal Society in London, and he was selected as Fellow there in 1765 and as a member of the American Philosophical Society in 1768. Winthrop was awarded an honorary LL.D. from the University of Edinburgh in 1771 and from Harvard in 1773. His was the first honorary LL.D. awarded by Harvard.
Winthrop married Rebecca Townsend in 1746, and they had five sons: John (1747-1800; Harvard AB 1765), Adam (1748-1774; Harvard AB 1767), Samuel (1750-1751), James (1752-1821; Harvard AB 1769), and William (1753-1825; Harvard AB 1770). Although he and Rebecca lived with Harvard's President Holyoke in Wadsworth House at the beginning of their marriage, they later moved to a house on the northwest corner of Mount Auburn and Boylston streets. Rebecca died in August 1753, and several years later, on April 8, 1756, Winthrop married Hannah Fayerweather (see below). Hannah outlived him by more than a decade. Drawn to the patriot cause but in poor health at the time of the American Revolution, Winthrop served in the revolutionary Massachusetts Provincial Congress as a representative of Cambridge, and in September 1775 he was appointed a Judge of Probate for Middlesex County. John Winthrop died in Cambridge, Massachusetts on May 3, 1779.
After John's death in 1779, Hannah continued to live in their Cambridge house, but began taking on boarders as a means of support. In the weeks following the death of Professor Winthrop, a Committee inventoried the College's scientific apparatus and provided a report with a section titled "At the House of Mrs. Winthrop" that included a clock, three telescopes, a standing quadrant, a hydrostatic balance, a Fahrenheit thermometer, and a Spirit-level. In April 1780, the College collected the equipment from the Winthrop house, and on April 20, 1780, Hannah wrote to Warren, "My poor wounded heart was most exquisitely touchd by a requistion of those enlightening Tubes thro which He often led me to View the wonders of creating power, but a Successor must enjoy all those advantages." Hannah Winthrop died on May 6, 1790.
