thumb|The Marx Brothers (clockwise: Groucho, Chico, and Harpo) by Yousuf Karsh in 1948 In 1961, Harpo published his autobiography, Harpo Speaks! Because he did not speak in any of his film appearances, many moviegoers believed he actually was mute. In fact, radio and TV news recordings of his voice can be found on the Internet, in documentaries, and on bonus materials of Marx Brothers DVDs. A reporter who interviewed him in the early 1930s wrote that Harpo "had a deep and distinguished voice, like a professional announcer", and like his brothers, spoke with a New York accent his entire life. According to those who personally knew him, Harpo's voice was much deeper than Groucho's, but it also sounded very similar to Chico's. His son, Bill, recalled that in private, Harpo had a very deep and mature soft-spoken voice, but that he was "not verbose" like the other Marx brothers, instead preferring to listen and learn from others.
