I read once (in Penthouse, I think) that there was a famous sex scandal in New Haven in the 1920s – an underage townie nymphette named Susie slept (or whatever) with several hundred Yale men. I forget how it came out. The police investigator asked her to pick them all out of a set of photos of all the undergrads and, after she picked the first few, he couldn’t take any more and closed the book; only those were prosecuted. Supposedly this story was the inspiration for the song “If You Knew Susie,” which if true adds significance to the original lyrics (cleaned-up film rendition here). Is this true? The Wikipedia article on the song doesn’t mention it.
I can’t find any evidence of this.
In fact, I’ll bet it’s a fanciful or embellished version of this later case, from the book Make love, not war by David Allyn.
Short version. In the 1959-1960 school year, a 14-year-old local girl named Susie made the rounds of the dorms at Yale giving blow jobs. She got caught and arrested. (Since she wasn’t charging money it’s not clear on what charge.) Eight Yalies were charged with something called “lascivious carriage” and suspended for a year. Many others dropped out before they could be tried. Susie was given a Yale yearbook and told to pick out faces. That’s the part that makes me think it’s the same story.
