Author John Winthrop (1714-1779), a descendant of the founder of the Massachusetts Bay Colony, was elected Hollis professorship of mathematics and natural philosophy at Harvard aged only twenty-three. 'He explored the fields of astronomy, mathematics, and seismology with diligence and flair, publishing eleven articles in the Philosophical Transactions of the Royal Society. His achievements in astronomy, particularly in the study of comets and the relationship between sunspots and the sun's aurora, have been especially celebrated. Winthrop was also a dedicated teacher, explaining the work of other scientists and his own to students and the public at large through lectures, demonstrations, and a host of newspaper and magazine articles' (ODNB).
