Peter Mark Roget

About Peter Mark Roget

Peter Mark Roget was a British physician, natural theologian, lexicographer, and founding secretary of The Portico Library. He is best known for publishing, in 1852, the Thesaurus of English Words and Phrases, a classified collection of related words (thesaurus). In 1824, he read a paper to the Royal Society about a peculiar optical illusion which is often (falsely) regarded as the origin of the ancient persistence of vision theory that was later commonly, yet incorrectly, used to explain apparent motion in film and animation.
