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.{{cite journal|author=Anderson, John|author2=Anderson, Barbara|title=The Myth of Persistence of Vision Revisited|journal=Journal of Film and Video|year=1993|volume=45|issue=1|pages=2–12}}

Early life

File:Peter Mark Roget plaque, Edinburgh University.jpg]]

Peter Mark Roget was born in Broad Street, Soho, London, the son of Jean (John) Roget (1751–1783), a Genevan cleric born to French parents, and Catherine "Kitty" Romilly, the sister of British politician, abolitionist, and legal reformer Sir Samuel Romilly. His parents were French Huguenots.{{cite ODNB|id=24008|first=T. Jock|last=Murray|title=Roget, Peter Mark}}{{cite book |title=Proceedings of the Huguenot Society of London |date=1911 |publisher=Huguenot Society of London. |volume=9 |page=546 |url=https://books.google.com/books?id=NUhNAQAAMAAJ&pg=PA546 |language=en}} Following his father's death, the family moved to Edinburgh in 1783 where Roget later studied medicine at the University of Edinburgh, graduating in 1798. Samuel Romilly, who took on the role of surrogate father to Roget and supported his nephew's education, also introduced him into Whig social circles.{{cite book |last1=Desmond |first1=Adrian |title=The Politics of Evolution: Morphology, Medicine, and Reform in Radical London |date=1992 |publisher=University of Chicago Press |isbn=9780226143743 |pages=222–3 |url=https://books.google.com/books?id=-fkLzEwjWycC&pg=PA222 |language=en}}

Roget then attended lectures at London medical schools. Living in Clifton, Bristol, from 1798 to 1799, he knew Thomas Beddoes and Humphry Davy and frequented the Pneumatic Institute.{{cite book |last1=Fullmer |first1=June Z. |title=Young Humphry Davy: The Making of an Experimental Chemist |date=2000 |publisher=American Philosophical Society |isbn=9780871692375 |page=[https://archive.org/details/younghumphrydavy0000full/page/131 131] |url=https://archive.org/details/younghumphrydavy0000full |url-access=registration |language=en}}

Not making a quick start to a medical career, in 1802 Roget took a position as a tutor to the sons of John Leigh Philips, with whom he began a Grand Tour during the Peace of Amiens, travelling with a friend, Lovell Edgeworth, son of Richard Lovell Edgeworth. When the Peace abruptly ended he was detained as a prisoner in Geneva. He was able to bring his pupils back to England in late 1803, but Edgeworth was held in captivity until Napoleon fell on 6 April 1814.

Medical career

With the help of Samuel Romilly, Roget became a private physician to William Petty, 1st Marquess of Lansdowne, who died in 1805. He then succeeded Thomas Percival at Manchester Infirmary and began to lecture on physiology. He moved to London in 1808 and in 1809 became a licentiate of the Royal College of Physicians. After an extended period of dispensary work and lecturing, in particular, at the Russell Institution and Royal Institution, he was taken onto the staff of the Queen Charlotte Hospital in 1817. He also lectured at the London Institution and the Windmill Street School.{{cite web |title=Munks Roll Details for Peter Mark Roget |url=http://munksroll.rcplondon.ac.uk/Biography/Details/3839 |website=munksroll.rcplondon.ac.uk |access-date=16 May 2019 |archive-date=16 November 2023 |archive-url=https://web.archive.org/web/20231116060211/http://munksroll.rcplondon.ac.uk/Biography/Details/3839 |url-status=dead }}

In 1823 Roget and Peter Mere Latham were brought in to investigate disease at Millbank Penitentiary. In 1828 Roget, with William Thomas Brande and Thomas Telford, submitted a report on London's water supply. In 1834 he became the first Fullerian Professor of Physiology at the Royal Institution. One of those who helped found the University of London in 1837, he was an examiner in physiology there. He gave up medical practice in 1840.

Thesaurus

Roget retired from professional life in 1840, and by 1846 was working on the book that perpetuates his memory today. It has been claimed that Roget struggled with depression for most of his life, and that the thesaurus arose partly from an effort to battle it.{{cite news|title=The man who made lists to fend off depression|author=Spiegelman, Arthur|url=http://ca.reuters.com/article/oddlyEnoughNews/idCAN2628269520080328|archive-url=https://web.archive.org/web/20080409173544/http://ca.reuters.com/article/oddlyEnoughNews/idCAN2628269520080328|url-status=dead|archive-date=9 April 2008|access-date=4 May 2008|work=Reuters|date=28 March 2008}} A biographer stated that his obsession with list-making as a coping mechanism was well established by the time Roget was eight years old.{{cite news|title=Obsessed (Agog, Beset, Consumed, Driven, etc.)|author=Mallon, Thomas|url=https://www.nytimes.com/2008/03/16/books/review/Mallon-t.html|access-date=4 May 2008|work=The New York Times|date=16 March 2008}} In 1805, he began to maintain a notebook classification scheme for words, organized by meaning. During this period he also moved to Manchester, where he became the first secretary of the Portico Library.{{cite book |last1=Rennison |first1=Nick |title=Peter Mark Roget: The Man Who Became The Thesaurus - A Biography |date=2015 |publisher=Oldcastle Books |isbn=9781843447931 |page=30 |url=https://books.google.com/books?id=dQpOCgAAQBAJ&pg=PT30 |language=en}}

The catalogue of words was first printed in 1852, titled Thesaurus of English Words and Phrases Classified and Arranged so as to Facilitate the Expression of Ideas and Assist in Literary Composition. During Roget's lifetime, the work had twenty-eight printings. After his death, it was revised and expanded by his son, John Lewis Roget (1828–1908), and later by John's son, the engineer Samuel Romilly Roget (1875–1953).{{cite journal|url=https://ieeexplore.ieee.org/document/796030|title=Roget's Engineering Successor [i.e. S.

Roget was elected a Fellow of the Royal Society in 1815, in recognition of a paper on a slide rule with a loglog scale. He was a secretary of the Society from 1827 to 1848. On 9 December 1824, Roget presented a paper on a peculiar optical illusion to the Philosophical Transactions, which was published in 1825, as Explanation of an optical deception in the appearance of the spokes of a wheel when seen through vertical apertures.{{cite journal|url=http://rstl.royalsocietypublishing.org/content/115/131.full.pdf+html|last=Roget|first=Peter Mark|year=1824|title=Explanation of an optical deception in the appearance of the spokes of a wheel when seen through vertical apertures|journal=Philosophical Transactions of the Royal Society of London|volume=115|pages=131–140|doi=10.1098/rstl.1825.0007|s2cid=144913861|doi-access=}}{{cite book |last1=Crary |first1=Jonathan |title=Techniques of the Observer: On Vision and Modernity in the Nineteenth Century |date=1992 |publisher=MIT Press |isbn=9780262531078 |page=[https://archive.org/details/techniquesofobse0000crar/page/106 106] note 19 |url=https://archive.org/details/techniquesofobse0000crar |url-access=registration |language=en}} The paper was noted by Michael Faraday and by Joseph Plateau, who both mentioned it in their articles that presented new illusions with apparent motion.{{Cite web | url=https://books.google.com/books?id=ezcDAAAAQAAJ&pg=PA394 |title = Correspondance mathématique et physique, publ.

One of the promoters of the Medical and Chirurgical Society of London, of which he was the President in 1829, and which later became the Royal Society of Medicine, Roget was also a founder of the Society for the Diffusion of Useful Knowledge, writing a series of popular manuals for it. He wrote numerous papers on physiology and health, among them the fifth Bridgewater Treatise, Animal and Vegetable Physiology considered with reference to Natural Theology (1834), and articles for the Encyclopædia Britannica. He was hostile to phrenology, writing against it in a Britannica supplement in 1818, and devoting a two-volume work to it (1838).{{cite book |last1=Haskins |first1=Roswell Willson |title=History and Progress of Phrenology: (Read Before the Western Phrenological Society, at Buffalo,) |date=1839 |publisher=Steele & Peck |pages=[https://archive.org/details/2556039R.nlm.nih.gov/page/n200 181]–3 note |url=https://archive.org/details/2556039R.nlm.nih.gov |language=en}}

In later life Roget became deaf and was cared for by his daughter, Kate. He died aged 90 while on holiday in West Malvern, Worcestershire and was laid to rest in St. James Church cemetery, West Malvern.

In literature

Canadian writer Keath Fraser published a story, Roget's Thesaurus, in 1982, which is narrated in Roget's voice. He has Roget speak on his wife's death, from cancer.{{cite book |last1=Metcalf |first1=John |title=Shut Up He Explained |date=2007 |publisher=Biblioasis |isbn=9781897231746 |page=286 |url=https://books.google.com/books?id=8DuCCgAAQBAJ&pg=PA286 |language=en}}

Roget also appears in Shelagh Stephenson's An Experiment with an Air Pump, set in 1799, as the only historical character. The play is set in the fictional household of Joseph Fenwick, and Roget is one of Fenwick's assistants.{{cite web |title=Theatre review: An Experiment with an Air Pump at Lion and Unicorn Theatre|first=Howard|last=Loxton |url=https://www.britishtheatreguide.info/reviews/exptairpump-rev.htm |website=British Theatre Guide|date=2011}}
