The Marriage Art by John E. Eichenlaub, M.D. (Dell, 1961)
This book was surprising. Even though it’s one of the more recently published books in my collection, Dr. Eichenlaub’s advice is often more archaic and misogynist towards women than my books from the 1920s and ’30s. And although the book is “for married couples,” it’s almost entirely written from a “husbands, here’s how to get your wife to have sex” stance.
Interestingly, other books Eichenlaub has written includes A Minnesota Doctor’s Home Remedies for Common and Uncommon Ailments and New Approaches to Sex in Marriage. I think it’s safe to assume the latter’s advice for wives included the gem, “Stop crying.”
