Appears as 'Nicholas Clausen Parish St.Martin in the fields' in the Naturalization Act of 1709, with witnesses Godfried Wittich and Sven Holst, which suggests Swedish rather than German origin. Made free of the Haberdasher's Company by redemption 1 July 1709 as 'Nicolaus Clauson', without details of address or occupation, and there appears to be no other reference to him in that company's records. First mark entered as largeworker, 10 June 1709, a date earlier than that recorded for his freedom. Address: Orange Street, near Leicester Fields. 'Free of the Haberdashers'. Second (Sterling) mark, 29 July 1720. Heal records him at Orange Street till 1723. In spite of his Scandinavian origin his work, admittedly rare in survival, is typical of the Huguenot school, his latest and greatest achievement being the Imperial Throne of 1731 in the Hermitage, Leningrad.
