Hello how may I help you? I would like to know a world record. I'm here to help! What world record would you like to know about? Who is the tallest person in the world? Do you mean the tallest person living now or the tallest of all time? Of all time, I guess. The tallest person of all time was Robert Pershing Wadlow. He was 8 feet, 11.1 inches tall. That's so tall! Where was he from? He was born in Alton IL, USA. Interesting. Well, thanks for the information. Goodbye. You are welcome!
