verna is his maternal family name. He was born in Buenos Aires on October 31, 1914. He grew up in the neighborhood of Almagro; when he was a teenager he attended classes with professor José López. His friend Ángel Gálvez was for him the «model dancer». In 1964 he began to dance with Carmencita Calderón, his dancing partner for nearly thirty years. He possessed an elegant technique with postures that awoke the admiration of connoisseurs. Juancito was the prototype of the passionate dancer. We may say that tango for him was not a choreographic display but a tough guy’s rite. His way was a clean and straight tango which went from feeling to feet always passing through his wrist. He was a master in the art «of leading». He shone by making his partner stand out. He is author of the book Los olvidados bailarines de tango (The Forgotten Tango Dancers) in which he also wrote his memoirs.
