I used a newspaper search engine to find Holmes as referenced in the year 1920, a hundred years ago. There are thousands, though I was limited to English language papers. If I simply search for “Sherlock Holmes” in the same digitized papers (since Sherlock crawled out of Conan Doyle’s head) the number is 1,747.746.
The Times Greater London: One of the quaint characteristics of our postwar world is certainly a great increase in the “agony” (newspaper personals) column habit, even twenty years ago, a sedate thing, mostly appeals from hospitals. It was very rarely a personal advertisement, or one one of those intriguing cryptograms which Sherlock Holmes would disentangle.’ 4 AUG 1920
Bingham, Utah Bulletin, USA: A new ouija board story not far from Bingham, worthy of the attention of Sherlock Holmes. That ouija actually gave a certain man the name and address of a woman, even to the street number and so on, who lives four thousand miles away–beyond the sea–and that wicked board even told the man something to tell her!
The Manchester Guardian, England: There is a powerful god-in-the-machine in the person of the family doctor, a philosophic Sherlock Holmes of the profession who sees through everyone and their intrigues. 30 Nov 1920

Honolulu Star-Bulletin, Hawaii: But a man does not have to be a Sherlock Holmes to be able to deduce from her general conduct and conversation, whether his coming really does set the golden bells ringing. (a front page article, “The Test of Love.”)

Montreal Gazette, Canada: Scotland Yard is now accoutered with a mechanism for scientific crime detection that would have made even that incurable scoffer, Sherlock Holmes, open his eyes in astonishment. (excerpted ‘Eye-Opener for Holmes,’ about use of planes in police intelligence, 25 Dec 1920.)
