George Ravenscroft (1632 – 7 June 1683) was an English businessman in the import/export and glass making trades. He is primarily known for his work in developing clear lead crystal glass (also known as flint glass) in England.
Little is known about Ravenscroft’s personal life, character or appearance, though his father described him in his will as a responsible family man and an astute businessman. He was born in 1632, the second of five sons of Roman Catholic parents who hid their true faith and lived outwardly as Anglicans, and he was baptized in Alconbury Weston, England, in April 1633. From 1643 to 1651 Ravenscroft attended the English College in Douai, France to train for the priesthood, but he dropped out before finishing his training and returned to London by 1666.
After settling in London and establishing a successful import/export business that made him wealthy, Ravenscroft married Hellen Appleby, from Yorkshire, England, in 1670 or 1671 and had three children with her. In 1684 his widow subsequently married Sir Thomas Sheridan (politician), Chief Secretary of State for Ireland (1687-1688). Ravenscroft died on 7 June 1683 after suffering from "a " and was buried in the Ravenscroft vault in the Church of St. John the Baptist in Chipping Barnet, North London, England. Today in Chipping Barnet a school, a park, a garden, and a road are called Ravenscroft, suggesting the importance of the Ravenscroft family in the area at one time.
Ravenscroft’s whereabouts and activities between 1651 and 1666 are unclear, though it is certain that he lived in Venice, Italy for at least some of this time working as a merchant and possibly learning glassmaking techniques that he would later bring back to England. At some point he established a successful import/export business in Venice with two of his brothers, Francis and James.
