What is the name of the author of "The Adventure of the Speckled Band"?

The Adventure of the Speckled Band was written by Sir Arthur Conan Doyle, whose name is sometime abbreviated as "ACD." This particular story in the Sherlock Holmes series was first published in February of 1892. In this adventure, Mr. Sherlock Holmes and Dr. John Watson are asked by Miss Helen Stoner to figure out what is going on at her home. Miss Stoner fears that someone or something may be trying to kill her because her sister died years prior in circumstances very similar to her own. 

It has been proposed that the Sherlock Holmes stories are semi-autobiographical, with Doyle himself being represented by the character of Dr. John Watson. Though the content of the stories is most certainly fictional, Doyle did state that he was inspired to create the character of Sherlock Holmes by his once-professor Dr. Joseph Bell and his powerful skills of observation.
