William Billingsley (1758–1828) was an influential painter of porcelain in several English porcelain factories, who also developed his own recipe for soft-paste porcelain, which produced beautiful results but a very high rate of failure in firing. He is a leading name associated with the English Romantic style of paintings of groups of flowers on porcelain that is sometimes called "naturalistic" by older sources, although that may not seem its main characteristic today.
