The first line of https://en.wikipedia.org/wiki/Logo_(programming_language) is "Logo is an educational programming language, designed in 1967 by Wally Feurzeig, Seymour Papert, and Cynthia Solomon." so you are correct but it is nice to mention his co-inventors. I agree about the book. I had to borrow it from a friend, read it quickly and give it back in 1983 so my memories of it are a bit fuzzy.
