A miniature horse famous for being the world’s smallest horse at birth is celebrating its 14th birthday. Einstein was born in New Hampshire on April 22, 2010, and weighed an astonishingly small 6 pounds and stood 14 inches tall, setting a world record as the planet’s smallest newborn horse. He was three pounds lighter than the previous record holder. >> ARCHIVE VIDEO: Einstein becomes international sensation (originally aired 2010)Breeders told WMUR at the time that what really set Einstein apart was his proportions."The head, to the legs, the length, width, height, everything's just beautiful about this little horse," Charlie Cantrell, Einstein's co-owner, told WMUR at the time. Einstein lived in Bellingham, Washington for about six or seven years, returning to New Hampshire in October 2020. During his time across the country, Einstein grew a little bit. “He’s a little wider than he was (before),” Cantrell said then.Einstein had an “awesome life” while in Washington, but Cantrell said he’s happy to be spending more time again in New Hampshire.“He’s happy and smart and does all the things small horses do,” Cantrell said.Cantrell and his wife, Rachel Wagner, have written multiple children’s books featuring Einstein.
