Do you know of the author E. Michael Jones? You might be interested in his books Degenerate Moderns and Dionysius Rising. Jones details the unsavory personal histories of several pillars of modern thought (Freud, Mead, Kinsey, Wagner et al.) and shows how their private lives influenced their thinking and art.
You could probably write an endless series of such books. Douglas would rate an especially fat chapter in one.
"Intellectuals" by Paul Johnson is a romp along the same lines.
As would both Hillary and bill.
