Medical man -

After graduating, Conan Doyle set up a medical practice in Portsmouth, in 1882. It was less than successful. He opted instead to study ophthalmology in Vienna. Upon his return to London, Conan Doyle opened a small office and consulting room in Westminster, but received next to no patients. Disillusioned, he again tried his hand at writing fiction.

Finding a publisher -

'A Study in Scarlet' was written in three weeks when Conan Doyle was 27 years old. He struggled to find a publisher, but eventually the story was accepted by Ward Lock & Co.

Inspiration for Sherlock Holmes -

For his fictional detective, Conan Doyle was inspired by a real-life lecturer of his at the University of Edinburgh, Dr Joseph Bell. Apparently the physician could diagnose patients simply by looking at them when they walked into his surgery.

Influenced by Poe -

Conan Doyle was also influenced by American writer Edgar Allan Poe's fictional sleuth, C. Auguste Dupin, who made his first appearance in Poe's 1841 short story 'The Murders in the Rue Morgue.'

Lippincott’s Monthly Magazine -

'A Study in Scarlet' didn't sell well. But one person who had admired the novel was Joseph Stoddart, who edited Lippincott's Monthly Magazine. During a dinner party, he convinced a crestfallen Conan Doyle to pen a second novel featuring the detective. Also present at the table was Oscar Wilde, who was encouraged by Stoddart to submit for inclusion in the same publication his only novel—'The Picture of Dorian Gray.'

'The Sign of the Four' -

Who was Irene Adler based on? -

'A Scandal in Bohemia' features a fictional character named Irene Adler. A former opera singer and actress, she is one of the most beguiling female characters in the Sherlock Holmes series, despite appearing in only one story. Speculation continues to this day as to who the author based Adler on. Suggestions include Lola Montez (pictured), a dancer and mistress of King Ludwig I of Bavaria, and the actress Lillie Langtry, the lover of Edward, the Prince of Wales.

"Elementary, my dear Watson" -

Contrary to popular belief, Holmes never uttered the immortal line "Elementary, my dear Watson" in any of Conan Doyle's novels, at least not together. In 'The Adventure of the Crooked Man' (1893), both of these components are included. But there are 52 words between them!

Sherrinford Holmes? -

Arthur Conan Doyle's fictional detective was nearly called Sherrinford after the author's admiration for a cricketer who bore the name. Conan Doyle was passionate about the sport, and played for Marylebone Cricket Club between 1899 and 1907. He's pictured at age 14 with cricket bat in hand.

Character traits -

As per the books, the character of Sherlock Holmes suffers from Asperger's syndrome, bipolar disorder, and savant syndrome.

Why is Holmes so hot? -

Conan Doyle originally envisaged his crime fighter as balding and lacking in good looks. It was British illustrator Sidney Paget who used his artistic license to make Holmes more attractive and refined in character—even drawing in his famous deerstalker cap. Paget's popular image of Holmes, originally unveiled in The Strand Magazine, has endured to this day.

Affairs of the heart -

Sherlock Holmes is asexual, with no erotic leanings towards men or women. In 'The Adventure of the Lion's Mane,' Holmes writes, "Women have seldom been an attraction to me, for my brain has always governed my heart."

Bad habits -

Holmes' obvious indulgence is his pipe, much to Dr. Watson's dismay. But the detective occasionally turns to questionable stimulants (his choice of recreational drugs were not illegal in the 19th century). Image: Sidney Paget (1860–1908)

Does 221B Baker Street exist? -

Conan Doyle had Sherlock Holmes residing at 221B Baker Street in London. While it's one of the most famous addresses in literature, 221B doesn't actually exist. Well, not quite. The Sherlock Holmes Museum bears the official address '221B,' though the building sits between 237 and 241 Baker Street, making it physically—if not officially—at number 239.

Crime scene -

'The Final Problem,' published in 1893, ends with the demise of Sherlock Holmes and the criminal mastermind Professor James Moriarty, with both plunging to their deaths over the Reichenbach Falls near Meiringen, in Switzerland. However, the public outcry surrounding the sleuth's dramatic passing was such that Conan Doyle was persuaded to revive the detective for additional stories and novels.

'The Hound of the Baskervilles' -

Sherlock Homes reappeared along with Dr. Watson in 'The Hound of the Baskervilles.' Published in 1902, the story is set before the fateful confrontation with Moriarty in Switzerland and is one of the most famous novels ever written.

Belief in spiritualism -

Sir Arthur Conan Doyle had a longstanding interest in spiritualism and mystical subjects. This led to an unlikely friendship with Harry Houdini, whom Conan Doyle believed possessed the spiritual gift of "dematerialization" because of Houdini's remarkable gift for illusion. The pair are pictured shaking hands on the SS Adriatic as Conan Doyle prepares to depart for England after visiting the United States.
