Radiolab logoSusan Schaller, author of A Man Without Words, recently appeared on WNYC’s Radiolab for a show about language. Fans of Radiolab will love this episode, which examines the conundrums of language in its trademark irreverent style.

Schaller describes her experiences teaching Ildefonso, a 27-year-old deaf man who had lived his entire life without any comprehension of words, to use sign language—a story she recounts in the book. Listen to the broadcast and find out why Schaller believes that teaching Ildefonso was “the best idea she ever had in her life.”
