Horne Thornthwaite and Wood were opticians, optics, scientific instrument makers and camera and equipment manufacturers. Founded by William Henry Thornthwaite (b 1819), optician, Fallon Horne (d 1858), and camera manufacturer Edward George Wood.
Between its foundation in 1841, and its closure in about 1913, this triple partnership changed its name repeatedly, sometimes as Horne, Thornthwaite and Wood, sometimes just Horne and Thornthwaite.
