It's hard to believe, but Norton Juster and Jules Feiffer's children's classic The Phantom Tollbooth is turning 50 this year. Millions of children (and adults, too—check out Adam Gopnik reminiscing in a recent New Yorker article) have been enchanted by the surreal tale of Milo and his trip to the Kingdom of Wisdom, but not everyone knows that Juster and Feiffer wrote the book while living in the same building in Brooklyn Heights.

"I was living in Brooklyn Heights with Jules in a big old decrepit duplex apartment. I had been looking for a place to live and he just happened to be living above [what became] my basement room. That was in the 1950s and it was a very different place," Juster told the Wall Street Journal last month. “In Brooklyn, people live together and wind up collaborating — there’s something very special about this place,” Keara Duggan of the Brooklyn Historical Society told the Brooklyn Paper.

If you're itching for a trip down memory lane, the BHS will be hosting a special 50th anniversary celebration for the book on Sunday, November 13, with Juster and fellow Brooklyn Heights-er Leonard Marcus, author of the The Annotated Phantom Tollbooth. Brooklyn Heights Blog posted a video of Juster and Feiffer in front of the brownstone they lived in—see if you can figure out where it is:
