Instrument maker and barometer engraver Joseph Somalvico settled in London around 1780 working from no. 87 Holborn as a high quality barometer maker. He later moved to no. 67 Leather Lane, Holborn. Between 1805 and 1810 he worked in partnership with Domenico [Domenick] Lione, producing some of the finest wheel barometers of the period. Active until around 1820, the business was continued by his sons Giacomo and Carlo who moved it to Hatton Gardens. The firm of J. Somalvico & Co. thrived well into the nineteenth century.
