label: Description
content: Francis Herbert Wenham (b. 1824), an English engineer and active microscopist, designed a four-sided prism suitable for binocular microscopes around 1860. Several London opticians were offering instruments of this sort by 1861, and some showed examples at the London Exhibition of 1862. Baker began advertising binocular microscopes in 1867; the Royal Microscopical Society bought an example the following year.
