Horowitz was born in 1903, but in order to make him appear too young for military service so as not to risk damaging his hands, his father took a year off his son's age by claiming he was born in 1904.
Horowitz 1903'te doğdu ama askerlik görevinde ellerine zarar verme riskini engellemek için babası oğlunun 1904'te doğduğunu iddia ederek, doğum yaşından bir yıl genç gösterdi.
