While never directly using the verbatim terms, "involuntarily celibate" or "incel," famous French author [[Michel Houellebecq]] has written about the topic vicariously through his many fictional works about [[involuntarily celibate]] and layless men. Famous English novelist and non-fiction writer George Orwell also briefly touched upon [[involuntarily celibate]] (without explicitly using the term) tramps in his book about the lives of the underclass, Down and Out in Paris and London, in 1933.
