He worked from 199 Piccadilly from the death of Jesse Ramsden until 1817.
A very collectable and desirable scientific instrument.
Note: Jesse Ramsden was one of the greatest scientific instrument makers of the eighteenth century. His workshop was the largest in London. He invented the first accurate dividing engine and devised and improved many instruments. When he died in 1800 he left his workshop and his dividing engine to his foreman Matthew Berge in his will. The instruments under construction in the workshop at his death were all signed “Berge late Ramsden” so this instrument must have been completed shortly after 1800. Subsequently all instruments made in the workshop were signed simply “Berge London”.
