Gradually the ‘usefulness of science to the poorer classes and to the common purposes of life’ ceased to be the prime object of the Institution. The school for mechanics, the workshops, and the models, the kitchens and the Journals, died away; and the laboratory, the lectures, and the library became the life of the new Institution, and its object became ‘the diffusion of knowledge and the application of science to the improvement of arts and manufactures.’ The most memorable scientific incident in the history of the Rumford Institution was its relationship with Dr. Thomas Young. His lectures on physics must even now be held to rank as the greatest work in the literature of the Institution. As Professor and Superintendent of the House he had no great success; and he had no great influence on its fortunes; but by his genius he anticipated the progress of science, and his reputation has risen until it now ranks with that of Davy and Faraday. A short sketch of his life will bring this period of the history of the Institution to a close. Thomas Young was born in Somersetshire on June 13, 1773. Both his parents were Quakers, and to their tenets he was accustomed to attribute his resolution to effect any object on which he was engaged. This determination he brought to bear on all he did, and by this he educated himself almost from infancy ‘with little comparative assistance or direction from others.’ His earliest years were passed with a grandfather, a merchant at Minehead, who had some classical taste. He encouraged his precocious grandchild and often repeated to him that-- A little learning is a dangerous thing; Drink deep or taste not the Pierian spring. From 1780 to 1787 (7 to 14) he was chiefly at school. He gives an account of his acquirements in an autobiography written in Latin at this time--writing, arithmetic, Latin, Greek, mathematics, natural philosophy, introduction to the Newtonian philosophy, turning, telescope making, bookbinding, colour making, drawing, Hebrew, botany, fluctions, Priestly on Air, Italian, Chaldee, Syriac, Samaritan. He was a prodigy at fourteen. His father had a neighbour, a man of great ingenuity, by profession a land-surveyor, in whose office during the holidays the boy was given the use of mathematical and philosophical instruments and the perusal of three volumes of a dictionary of arts and science. He got some practical knowledge of land-surveying. This led him to botany; and to examine his plants he made a microscope. This required a knowledge of optics, and thence he went to mathematics and fluctions.
