51. You Can Hear What He Really Sounded Like
Although no known recordings exist of Marx speaking in public, it is actually possible for people today to hear what he sounded like. Someone found a copy of a home voice recording the comedian made while working on his autobiography where he recalls some of the crazy experiences of his youth. The recording confirms some surprising things.
First, Harpo sounds a lot like his brother Groucho; and second, he has a thick New York accent.
52. He Could Switch Gears
Despite spending his whole life as a comedian, Marx eventually got the chance to play a serious dramatic role. In a 1960 Christmas-themed television play called A Silent Panic, he portrayed a deaf-mute character who inadvertently witnesses a murder and struggles to decide how to react. The performance is available on YouTube, and is actually pretty darn impressive.
53. He Made One Sound On Film
Although he never had a spoken line in a Marx Brothers film, some believe Harpo did once let his voice slip in one of them. In 1939’s At The Circus, Harpo’s character releases an exaggerated sneeze by shouting “Ah-choo!” in a clear voice, though he could have been mouthing someone else’s voice. Even so, there is another instance people cling to.
54. He "Talked" On A Technicality
Sure, he never talked in his performances, but Harpo did actually have a line in a movie early on in his career—there’s just one problem. It was a silent movie, so the clip doesn’t get us any closer to hearing what he sounded like in a professional capacity. The clip consists of the silent Marx Brother soundlessly mouthing the words, “You sure you can’t move?”
55. His Marriage Miraculously Lasted
Despite being a Hollywood marriage, Marx and Susan Fleming shared a long, happy life together. More than that, he and Fleming adored raising their large family. Harpo once quipped that when it came to children, he wanted, "So many that whenever we go out, there can be one in every window, waving to us." So when Harpo did finally pass, he went out in an incredibly fitting way.
56. He Had Impeccable Timing
On September 28, 1964, Harpo passed at the ripe old age of 75, leaving behind his wife Susan Fleming, his four children, and his beloved Marx Brothers. However, there was something special about this day. Always good with timing, comedic or otherwise, Harpo actually died on the very day of his 28th wedding anniversary with Fleming, which must have been a bittersweet event for the widow. But when his funeral came around, it was a full-on tearjerker.
57. He Ruined His Brother
As one of the elder Marx brothers, Harpo was also one of the first of his siblings to go, and the news particularly devastated his brother Groucho. Later on, Groucho’s son Arthur Marx recalled that Harpo’s funeral was one of the first and only times he had ever seen his father cry. Then again, that was good old Harpo; he’d make you laugh until you cried.
58. He Didn't Talk For A Reason
Harpo is best-known as the Marx Brother who never talks, but few people know the reason why. According to some, it’s because when they were first starting out in Vaudeville, the brothers had a stomach-dropping realization: Harpo had intense difficulty memorizing lines. Rather than trying to fix this shortcoming, they decided to simply make his character mute and have his comedy focus on pantomime. However, there may be a much different explanation.
59. He Was Insecure
Another story suggests that Harpo may have lapsed into silence in his film career not so much out of a canny choice, but rather because of a scathing review that he took to heart. After seeing him in one performance playing his usual foolish character, one critic noted that Harpo only achieved the effect he was going for “until he spoke.” The comedian fell silent from then on.
