Of course, Jack's typist was very conveniently his brother Warnie. As an army Officer in Charge of Supplies Warnie would have had to spend many hours in front of a typewriter, filling out forms. He apparently typed very fast although he only used two fingers. And he believed wholeheartedly in his brother and his genius. Typing Jack's papers and correspondence gave him a purpose and was much more fulfilling than typing forms for the army.
In addition to never learning to type, Jack never learned how to drive. The scenes of him diving in Shadowlands are pure Hollywood. He loved to walk. He often walked all the way home to Headington from Oxford. He famously became convinced of the truth of Christianity while walking with Tolkien and Hugo Dyson. He took long walking tours with his brother and with other Inklings. On these tours the men would discuss philosophy, religion, and literary criticism. Somehow the movement of their legs, the rhythm of their steps would facilitate the movement of their thoughts. Thought and language are inseparable and rhythm is important to both.
The Royal typewriter captures beautifully the relationship between the two brothers. It captures their different personalities; Warnie's more technological bent, his love of machines, boats, train and Jack's literary leanings, his absorption in pre-modern worlds and fantasy. It illustrates their dependence on one another. Warnie needed Jack to keep him away from alcohol, loneliness, depression. Jack needed Warnie to ground him, to remind him of his childhood and to help him type his manuscripts and organize his immense correspondence.
First of all, artifacts like the Royal typewriter are great sources of inspiration, great triggers for one's own writing. The Royal typewriter gave me the idea to write a book about C.S. Lewis using the angle of his friendship with his brother.
Second of all, it is always good to be aware of the technologies that help us or hurt us while we are writing. What did we use when we first learned to write? What is habitual for us? Does our writing come out differently if we write a draft long hand before transitioning to the typewriter?
And when we choose a technology, how much do sound, rhythm and timing matter? Computers give us the ability to compose at lighting speed, but is that always good? Do we loose the sound or sense of what we are writing if we go too fast?
