Horace Darwin (1851-1928) was the fifth son and ninth child of Charles and Emma Darwin. In 1881 he co-founded the Cambridge Scientific Instrument Company with Albert George Dew-Smith (1848-1903), a British physiologist and photographer. Darwin led the company when the partnership ended in 1891. He was Mayor of Cambridge between 1896 and 1897, became a Fellow of the Royal Society in 1903 and was knighted in 1918.
