The thesaurus, a book that serves as a cross-reference for synonyms, and serves as a guide to effective and precise use of language, is a necessary tool of every writer and even some readers. Dr. Mark Peter Roget (1779–1869) was a British natural theologian, physician, and lexicographer. He suffered from depression his entire life: beginning at the age of eight, his coping mechanism was obsessive list-making. He wrote the first draft of the eponymous English-language thesaurus in 1805, two years prior to Webster beginning the undertaking of his own dictionary.
