At the Diogenes Club - 1928

"...There are many men in London, you know, who, some from shyness, some from misanthropy, have no wish for the company of their fellows. Yet they are not averse to comfortable chairs and the latest periodicals. It is for the convenience of these that the Diogenes Club was started, and it now contains the most unsociable and unclubable men in town. No member is permitted to take the least notice of any other one. Save in the Stranger's Room, no talking is, under any circumstances, allowed, and three offences, if brought to the notice of the committee, render the talker liable to expulsion. My brother (Mycroft) was one of the founders, and I have myself found it a very soothing atmosphere."

--Sherlock Holmes's description of The Diogenes Club in "The Adventure of the Greek Interpreter"
