James Ferguson (25 April 1710 – 17 November 1776) was a Scottish astronomer and instrument maker. Ferguson was born near Rothiemay in Banffshire of humble parents. According to his autobiography, he learnt to read by hearing his father teach his elder brother, and with the help of an old woman was able to read quite well before his father thought of teaching him. After his father taught him to write, he was sent at the age of seven for three months to the grammar school at Keith and that was all the formal education he ever received. His taste for mechanics was about this time accidentally awakened on seeing his father making use of a lever to raise a part of the roof of his house — an exhibition of strength which excited his wonder.

In 1734 he went to Edinburgh, where he began to make portraits in miniature, by which means, while engaged in his scientific studies, he supported himself and his family for many years. Subsequently he settled at Inverness, where he drew up his Astronomical Rotula for showing the motions of the planets, places of the sun and moon, &c.. He wrote various papers for the Royal Society of London, of which he became a Fellow in November 1763, devised astronomical and mechanical models, and in 1748 began to give public lectures on experimental philosophy. These he repeated in most of the principal towns in England. His deep interest in his subject, his clear explanations, his ingeniously constructed diagrams, and his mechanical apparatus rendered him one of the most successful of popular lecturers on scientific subjects. It is, however, as the inventor and improver of astronomical and other scientific apparatus, and as a striking instance of self-education, that he claims a place among the most remarkable men of science of his country.
