Hobbits, elves and Middle-earthlings across the globe will mark the 50th anniversary of J.R.R. Tolkien’s death this weekend. The English scholar and author best known for the worlds he created in “The Lord of the Rings” and other books died of pneumonia on Sept. 2, 1973, at age 81. Tolkien had a remarkable career, one which continues to touch lives, not only in his literature, but through the relationships he fostered, including one with his fellow Oxford don C.S. Lewis.
