Francis Eginton (1737–1805), was an English glass painter. He painted windows for cathedrals, churches, chapels and stately homes, etc., around the country, leaving 50 large works altogether; his work was also exported abroad. His masterpiece is The Conversion of St. Paul, for the east window of St Paul's Church, Birmingham. He also developed a method for reproducing paintings mechanically.
Eginton was the grandson of the rector of Eckington, Worcestershire, and was trained as an enameller at Bilston. As a young man he was employed by Matthew Boulton at the Soho Manufactory. In 1764 Eginton was employed as a decorator of japanned wares, but also did much work in modelling. During the next few years Boulton brought together a number of able artists at Soho, including John Flaxman and James Wyatt; and Eginton rapidly became a skilful worker in almost every department of decorative art.
Eginton was a partner with Boulton in the production of "mechanical paintings" or "polygraphs" The idea for these was in all probability taken by Boulton from a process modified by Robert Laurie (1755?-1836) from Jean-Baptiste Le Prince's 'aquatint' engravings. Eginton perfected the method and applied it to the production of coloured copies of paintings. More plates than one were required for each picture, and after leaving the printing-press Eginton finished them by hand. They were copied from the works of Philip James de Loutherbourg, Angelica Kauffman and other artists, and varied in price from £1. 10s. to £21. The largest were 40 inches by 50. They were sometimes mistaken for original paintings, although these old "polygraphs" were in fact nearly identical to the varnished coloured oleographs which later became prevalent, the main difference being that the latter were printed lithographically.
