In 1744, Edgeworth was born in Bath into a landowning family which owned property in Ireland. At school he showed an interest in mechanics. In 1761, he went to Trinity College Dublin, followed by Oxford University. After his first marriage in 1763, he settled in Maidenhead and he invented various machines, including a land-measuring machine, turnip cutter and carriages. The latter led to a friendship with Erasmus Darwin, who was also interested in carriage design.
He made his first visit to Lichfield in 1770 where his friends Erasmus Darwin and Thomas Day had settled, and met Anna Seward. Edgeworth and Day spent time in France in 1771, where they met Rousseau. After the death of his first wife in 1773, he married Honora Sneyd in Lichfield and when she died in 1780, he married her sister, Elizabeth. Her death led to a fourth marriage in 1798. Altogether, Edgeworth had nineteen legitimate children.
Edgeworth returned to his estates in Ireland in 1782, but he frequently spent time in England. In Ireland he engaged in agricultural and road improvement, work to improve the condition of his tenants, educational reform and politics. Most of Edgeworth’s publications on education, transport, and mechanics were produced after his move to Ireland. In 1798 Edgeworth collaborated with his daughter, Maria on Practical Education, which served as a manual for raising children into the nineteenth century. They stressed the importance of learning through play and what later generations would call discovery methods. By the time of his death in 1817, Edgeworth had left a reputation as an inventor, economic innovator and educator.
