The Story of Peter Mark Roget
Peter Roget was an accomplished doctor, lecturer, and inventor. Despite his success, he underwent a great deal of depression.
He retired from professional life by the age of 61. To cope up with depression, he started pursuing one of the things he really enjoyed doing — making lists. He devoted his time to creating a catalog of words organized by their meanings.
By age 69, he began the preparation for the publication of his project. Its first printed edition came out at age 73. It was called “Roget’s Thesaurus of English Words and Phrases”.
He kept working on it until his death at age 90 and later on revised and expanded by his son and grandson.
So next time you use a thesaurus, realize that it’s a result of a passion worth pursuing.
