John Ingram, London, Japan and Windsor chair manufacturer, fl. 1803-39 is in 1803, recorded at 1 Worship Street and from 1804 at 29 City Road, Finsbury Square. In 1812 the business was termed a 'Rustic Museum and Cheap Japan and Windsor chair Manufactory'. In the same year, after an auction to clear his warehouses of old stock, they were filled with "every description of fancy Japanned Windsor, mahogany and dyed chairs, sofas, couches, bedsteads, cornices, flower stands, garden and rustic seats, bridges, alcoves, summer-house etc."
See Dictionary of English Furniture Makers 1660-1840, Maney, page 472. To date this is the first known Windsor chair recorded with this name-stamp.
