1710–1776
A self-taught Scottish astronomer and instrument maker, he turned a few months of schooling into a life spent making science vivid for ordinary readers and lecture audiences. His books and demonstrations helped bring Newtonian astronomy within reach of people who had never studied mathematics.
Born in Banffshire, Scotland, in 1710, he came from a very modest farming family and had only a little formal schooling. Even so, he taught himself to read, developed a talent for mechanics, and became known for building and improving scientific instruments.
He eventually moved into a wider public world as a lecturer, writer, and demonstrator of astronomy and natural philosophy. His best-known books, including Astronomy Explained upon Sir Isaac Newton's Principles, were written to make difficult ideas clear to general readers rather than specialists.
His life is often remembered as a striking example of self-education in the Enlightenment era. Elected a Fellow of the Royal Society, he earned lasting recognition not only as an astronomer, but also as one of the great popularizers of science in 18th-century Britain.
