 As Liszt himself had been nicknamed "Putzig" (German for "little cute guy") by his own teacher, Carl Czerny, he began to call Cohen "Puzzi", a diminutive form of the word.Liszt accepted Cohen into his social circle, introducing him to his friends, the author George Sand and the radical priest, the Abbé de Lamennais, who both also became charmed by the boy.Sand began to dote on the boy and called him "Le Mélancolique Puzzi".
