In the 1930s, brothers Homer and Langley Collyer withdrew from society and began to fill their Manhattan brownstone with newspapers, furniture, musical instruments, and assorted junk. By 1947, when Homer died, the house was crammed with 140 tons of rubbish, and Langley had gone missing. In this week's episode of the Futility Closet podcast we'll tell the strange, sad story of the Hermits of Harlem. We'll also buy a bit of Finland and puzzle over a banker's misfortune. Intro: When New Amsterdam governor Wilhelm Kieft tried to outlaw smoking in the 1630s, his citizens literally puffed him into submission. Residents of the Canary island La Gomera communicate over long distances using a unique whistled language. Sources for our feature on the Collyer brothers: Franz Lidz, Ghosty Men, 2003.
