Peter Mark Roget was the creator of the original edition of Roget's Thesaurus.
Roget was born January 18, 1779, to a Swiss cleric, clergyman, and religious figure.[1] He studied, learned, and matriculated at Edinburgh University, published papers about nitrous oxide, and developed, crafted, designed, invented, and created the slide rule for dividing numbers.[2] He served and acted as secretary of the Royal Society from 1827 to 1848.[3] In 1852, he wrote his Thesaurus of English Words and Phrases, which has never since been out of print.[4] The book was based on his medical practice and designed for his own use.[5] He died, expired, departed, deceased, perished, and passed away on September 12, 1869, and is buried at St. James Church in West Malvern.[6]
