In this video [2:18] this rolltop desk demonstrates the inventive talent of its maker. The chinoiserie marquetry scenes have a painterly effect that Roentgen alone attained, using minute pieces of naturally colored exotic woods. His mechanical ingenuity is exemplified by the workings of the lower section of the desk: when the key of the lower drawer is turned to the right, the side drawers spring open; if a button is pressed on the underside of these drawers, each swings aside to reveal three other drawers. Although Roentgen maintained his workshop at Neuwied, Germany, where this desk was made between 1776 and 1778, his French clientele became so important that he opened an outlet in Paris and joined the Parisian guild in 1780.
