Richard Lovell Edgeworth (1744–1817) was a noted Irish educationalist, engineer and inventor. This two-volume autobiography, begun in 1808, was completed by his novelist daughter Maria, and published in 1820. Edgeworth's interest in education is evidenced by his reflections about how his childhood shaped his character and later life. Volume 1, written by Edgeworth himself and covering the period to 1781, reveals that his interest in science began early; he was shown an orrery (a moving model of the solar system) at the age of seven. As a young man, Edgeworth attended university in Dublin and Oxford, studied law, and eloped while still in his teens. He experimented with vehicle design, winning several awards, and was introduced by Erasmus Darwin to the circle of scientists, innovators and industrialists later known as the Lunar Society of Birmingham. In 1781 Sir Joseph Banks sponsored his election to the Royal Society.
