I thought that it was funny how he'd apparently go on rants about Jewis people, only for his wife to remind him who he was sleeping with.

Lovecraft was a pretty ridiculous human being in a lot of ways, but a lot of the Pulp crowd were interesting in one way or another. The bloke that invented the Shadow, for example, was a stage magician, while the man who created Conan the Barbarian was a kind of sheltered man who lived with his mother.

There's actually a really good book, the Chinatown Deathcloud Peril, which basically takes all these people like the creators of the Shadow and Doc Savage, and puts them in a story that has a lot of parallels with the plots of their stories. While they're assisted by a young Ron Hubbard, whoamongst other things, tells two teenagers called Siegel and Schuster that their idea of a man in a bodybuilding outfit with superpowers will never sell.
