Many years ago, at least 35, I read a story about an astronaut who bought a 'typewriter' for his daughter/niece. From what I remember, he was going to a space station and he bought an automatic typewriter for his daughter so that she could dictate letters to him. There was a module that would 'spell-check' and 'grammar-check' the letters. Over time the letters from the daughter got better and better. He thought the improvement was from improved technology, not realizing his daughter was maturing.
It was the first time I read about a word processor, many years before I ever saw one.
