Leonard Horner

Leonard Horner FRSE FRS FGS (17 January 1785 – 5 March 1864) was a Scottish merchant, geologist and educational reformer. He was the younger brother of Francis Horner.

Horner was a founder of the School of Arts of Edinburgh, now Heriot-Watt University and one of the founders of the Edinburgh Academy. A 'radical educational reformer' he was involved in the establishment of University College School. As a commissioner on the Royal Commission on the Employment of Children in Factories, Horner arguably did more to improve the working conditions of women and children in North England than any other person in the 19th century.

His father, John Horner, was a linen merchant in Edinburgh, and Leonard, the third and youngest son, attended the High School and entered the University of Edinburgh in 1799. There in the course of the next four years he studied chemistry and mineralogy, and gained a love of geology from Playfairs Illustrations of the Huttonian Theory. At the age of nineteen he became a partner in a branch of his father's business, and went to London.

In 1808 he joined the newly formed Geological Society of London and two years later was elected one of the secretaries. Throughout his long life he was ardently devoted to the welfare of the society; he was elected president in 1846 and again in 1860. In 1811 he read his first paper On the Mineralogy of the Malvern Hills (Trans. Geol. Soc. vol. i.) and subsequently communicated other papers on the Brine-springs at Droitwich, and the Geology of the S.W. part of Somersetshire.
