Do Jehovah's Witnesses have anyone recognized as a "prophet", or what kind of titles do they use?

I was looking for information about the founders of Jehovah's Witnesses. It looks like some notable early people were the founder Charles T. Russell and then Joseph F. Rutherford who was the president after Russell's death. The material at Jehovah's Witnesses websites (here , and here ) however does not provide a lot of information on the titles these or other leaders were referred by, or how their statements or writings were viewed. Example from paragraph 7 in an article titled "Methods of Preaching​—Using Every Means to Reach People" (located here ): > The second event was the death of Brother Russell on October 31, 1916. > Thus, The Watch Tower of December 15, 1916, announced: “Now that > Brother Russell has passed beyond, the sermon feature [in the > newspapers] will be discontinued entirely.” Although this avenue of > preaching came to an end, other methods, such as the “Photo-Drama of > Creation,” continued to have great success. Example from an article titled “When Are We Going to Have Another Assembly?”, located here : > During his visit, Brother Rutherford encouraged these faithful ones > very much with two motivating talks at the convention and five > lectures that were broadcast on the radio. The only reference to a title I have found so far is "brother". **Questions to JWs:** 1. Do you use any other titles ("Reverend"/"Prophet"/"Elder"/etc.) when referring to those who are currently, or have been in the past, in high standing in your organization? 2. Do you consider anybody currently alive, or anyone who has been on earth since Jesus, to be a prophet (someone put in position by God to foretell future events)? 3. Do you consider any current or past JWs to have been infallible? 4. Do you have any books or other writings that are considered sacred or infallible (excluding the Bible)?
