The world's shortest man, China's He Pingping has died at the age of 21 from apparent heart complications, the Guinness World Records book said.
Mr He suffered a form of primordial dwarfism and was just over 74cm (29 inches) tall. He was recognised as a world-record holder in 2008.
Mr He died on Saturday in Rome, where he was taking part in a TV show.
"For such a small man, he made a huge impact around the world," Craig Glenday, editor-in-chief of the London-based Guinness World Records, said in a statement.
"From the moment I laid on eyes on him I knew he was someone special - he had such a cheeky smile and mischievous personality, you couldn't help but be charmed by him.
"He brightened up the lives of everyone he met, and was an inspiration to anyone considered different or unusual."
Mr He was born in China's northern region of Inner Mongolia in 1988. According to the BBC, he was admitted to hospital two weeks ago after suffering a chest complaint.
He was a chain smoker and his family said he stopped growing after he turned 18.
