  ABDNP200975a02.JPG - Cambridge Scientific Instrument Co.: Galvanometer The Cambridge Scientific Instrument Co. were acknowledged for their innovative instruments, diversity of products and the high quality of their productions.  The company changed its name in 1920 after merging with R. W. Paul but kept its reputation. This astatic galvanometer is an impressive testament to the quality of their instruments.  It also reminds us that the optical galvanometer was the key instrument for sensitive electrical measurements for a whole century after its invention by Wm Thomson in 1858, originally constructed for the detection of signals transmitted by Atlantic submarine cable.
