I recall reading about Walser years ago. He was a celebrated writer as well as a somewhat controversial figure. Joining the Nazi party as a teenager at the end of WWII, Walser claimed someone else signed him up. In the early 1980s, there were some allegations of anti-Semitic tropes in a Walser book inspired by a Jewish literary critic he strongly disliked. Walser's books were still translated afterwards, though I have the sense that, unlike Grass and Boll, he was never widely read outside of Germany. The controversy put me off from reading him. In hindsight, that might have been an overreaction on my part.
