Happy Birthday, Peter Mark!

Peter Mark Roget was born today in 1779, in London.

His Thesaurus has been an invaluable tool for many writers - a work of genius. More people need lessons in how to use it, but that's not his fault. For one thing, he didn't intend it to be a dictionary of synonyms, but rather a classification of English's lexicon - "of the words it contains and of the idiomatic combinations peculiar to it, arranged, not in alphabetical order as they are in a dictionary, but according to the ideas which they express."
