Sherlock Holmes was not a real person but a character created by writer Sir Arthur Conan Doyle. This fiction hero "died" in the story "The Adventure of the Final Problem" published in 1893 in The Strand Magazine and then in "The Memoirs of Sherlock Holmes"
People were so concerned that Conan Doyle had to bring the great detective back. In 1901 Sherlock Holmes reappeared in "The Hound of the Baskervilles". The story supposedly happened before Holmes' "death" at the Reichenbach Falls in Switzerland.
Holmes returned officially from the dead in the 1903 story "The Empty House", which is the first story in the book "The Return of Sherlock Holmes"
Doyle wrote the Sherlock Holmes stories until 1927 though the chronology of Holmes' adventures ends with "His Last Bow", at the beginning of World War I in 1914.
Sir Arthur Conan Doyle died in 1930.

In the trailer, it shows a casket being lowered into a grave marked Sherlock Holmes: 18 something something to 1888. So it's safe to assume that he truly does die. But they could also do with this what Conan Doyle did after The Final Problem.
