How did Edith Piaf become famous?

In 1935 Edith Piaf was discovered on the streets of Paris by cabaret owner Louis Leplée, who gave the singer her first nightclub job. He began calling her “la môme piaf,” Parisian slang for “little sparrow,” a name she later adopted professionally. (Her birth name was Edith Giovanna Gassion.) That year Piaf made her theatrical debut, and shortly thereafter she was singing in the large music halls of Paris.
