If there was a Reformed Theology Hall of Fame my guess is Benjamin Breckinridge (B.B.) Warfield would be an immediate unanimous inductee. One of the last theology professors at Princeton who believed in the authority of the Bible, he wrote extensively and one of his stand-out works was on the canon of Scripture. On Christmas eve in 1920 he became very sick and it seemed to be the end but by February 16, 1921 he felt good enough to teach class only to die later that night.
