I’ve been working on the Walter Gropius lineage suggested by Ryan, and then also slowly going through the comments from reddit. (Down the line is Klee, who gets pulled over to Benjamin since Klee influences him through the painting ‘Angelus Novus’, owned by Benjamin)
H.L. Mencken and Max Stirner are two figures I hadn’t heard of, who are often described as similar to Nietzsche. Stirner comes before Nietzsche, part of the Young Hegelians, and is discussed by Friedrich Albert Lange who is later read by Nietzsche.
