DR PETER MARK ROGET:
Peter Mark Roget (January 18, 1779–September 12, 1869) studied medicine at the University of Edinburgh and became a distinguished physician and lexicographer. He was natural theologian. He also helped found the School of Medicine at the University of Manchester. He is best known for creating the Thesaurus of English Words and Phrases (Roget's Thesaurus), a classified collection of related words. He was also one of the founders of the Medical and Chirurgical Society of London, which later became the Royal Society of Medicine, and a secretary of the Royal Society. In 1815, Roget invented the log log slide rule, allowing a person to perform exponential and root calculations simply. This was especially helpful for calculations involving fractional powers and roots.
On December 9, 1824, Roget presented a paper entitled Explanation of an optical deception in the appearance of the spokes of a wheel when seen through vertical apertures. This article is often incorrectly referenced as either On the Persistence of Vision with Regard to Human Motion or Persistence of Vision with regard to Moving Objects, likely due to erroneous citations by film historians Terry Ramsaye and Arthur Knight (see Anderson and Anderson below).
