Charles Edwin Benham JP (/ˈbɛnəm/; 15 April 1860 in Colchester, Essex, England – 1 April 1929, also in Colchester) was a journalist who edited for many years the Essex County Standard, a published author of works such as Essex Ballads, and an amateur scientist-cum-inventor, which led him to create Benham's top, which was named after him.
Born on 15 April 1860 into a family of newspaper proprietors, Benham was educated at Colchester Royal Grammar School but did not attend university. He later returned to the school to become President of the Old Colcestrian Society for old boys of the school. Living in Colchester for all but a handful of years of his life spent with Mebrose printers in Derby - and, in turn, writing about it in many of his books - he helped edit the family-controlled paper the Essex County Standard jointly with his brother William Gurney Benham from 1892 until his death in 1929, which was described as "sudden and unexpected," from angina pectoris whilst in his editorial office for the newspaper. He left a widow.
In the spare time that his journalistic endeavours provided to him, Benham was a keen amateur scientist and contributor to the journal Nature. His obituary in Nature noted that Benham was "a representative of the type of scientific amateur of which British science has reason to be proud... by faithful observation and original mind he was able to make some notable contributions to knowledge." Most significantly, however, he is credited for his invention of Benham's top, the invention of which was relayed through an 1894 issue of Nature. The disc, when spun, produces the Fechner colour effect of vivid and coloured images of concentric circles, despite neither of these being present in the design. He was inspired to invent the said top after his correspondence with Dr. Gustav Theodor Fechner, who had demonstrated the illusory colour effect which the top propagated to English-speakers.
