Huguenot-descended papermaker whose firm, based at Bere Mill / Laverstoke in Whitchurch, Hampshire, won the Bank of England's banknote-paper supply contract in 1724 — the earliest such arrangement documented in the Bank's own institutional history, and one the Bank's 1969 *Quarterly Bulletin* describes as "a connection which has lasted till the present day." He matters to this vault specifically as the anchor for the earliest *Tier-1-confirmed* named papermaker in the Bank's watermark lineage, in contrast to the Sutton Courtenay / Rice Watkins 1697 attribution, which remains uncorroborated at that tier.
