yes, very much, he based Watson on himself! Funny huh!
Yes, twice, just like Watson, the first died of a severe sickness
The obvious answer would be that it was Arthur Conan Doyle himself. Doyle watched Doctor Bell as he used his powers of observation. Later he recorded this sort of thing by putting himself in the role of Dr. Watson as he wrote the Sherlock Holmes stories.
Conan Doyle liked spiritualism
Conan Doyle never says
Edgar Allan Poe's detective, crime and mystery novels influenced Sir Arthur Conan Doyle to write his own mysteries. Sir Arthur Conan Doyle believed that Edgar Allen Poe's stories were "a model for all time."
Agatha Christie is a similar author to Sir Arthur Conan Doyle. Both authors are known for their classic detective fiction, with Christie's most famous detective being Hercule Poirot and Miss Marple. Like Doyle, Christie's works feature intricate plots, unexpected twists, and memorable characters.
Dr. Watson did not say anything to Sherlock Holmes about "Algebra Pizzazz" as it is not a known reference or topic related to their interactions in Arthur Conan Doyle's Sherlock Holmes stories. Dr. Watson typically assisted Sherlock Holmes in solving complex criminal cases using deductive reasoning and keen observation skills rather than discussing algebraic puzzles or concepts.
Arthur Conan Doyle was inspired by one of his old masters in university. He was called Joseph Bell. Doyle admired Bell immensely for his cool attitude, razor-sharp mind and brilliant powers of deduction. Bell becamse Holmes, and Doyle became Watson. But Holmes' attire was based on someone else, the illustrator's younger brother.
The man himself? NO He was imagined and created in fiction by Sir Arthur Conan Doyle, a doctor and (to make ends meet) writer. Doyle learned to medically examine patients and observe them from Dr. Joseph Bell, who did some observations on his patients like Holmes. Many agree (as Doyle said himself) that Bell was the inspiration to Doyle to create Holmes.
He didn't like to have to wait for patients
If you meant what kind of nose did he have, hawk-like is the description given by Conan Doyle
