Sebastian Pether was an English landscape-painter who specialised in painting moonlight, sunset, and firelight. His father Abraham Pether and brother Henry Pether also specialised in moonlit paintings, the three were known as the "Moonlight Pethers". Sebastian's work tended to have greenish tones. The bulk of his work was managed through art dealers who helped him sell his paintings, but resulted in little income to support his large family of eleven. Pether died at the age of 51, leaving his family reliant on subscriptions raised after his death.

Henry Pether (1800–1880) was an English landscape painter famous for his depiction of moonlit scenes of 19th century Britain, Paris, and Venice. His father Abraham and older brother Sebastian Pether also painted moonlit scenes. Together they were known as the "Moonlight Pethers". He was also an inventor of lamps, architectural materials, and tiles.
