Halder became the first Bavarian and the first Catholic ever to become Chief of the German General Staff—a severe break with the old Protestant Prussian tradition of the officer corps. A man of wide intellectual interests, with a special bent for mathematics and botany (my own first impression of him was that he looked like a university professor of mathematics or science) and a devout Christian, there was no doubt that he had the mind and the spirit to be a true successor to Beck.
