Calvin Klein's father immigrated to the United States from Hungary. His mother was the daughter of Galicia (Eastern Europe) and Buchenland, Austrian Empire (modern day-Ukraine) immigrants.
Calvin Klein was born on November 19, 1942, in New York City, New York, the United States, to Flore (née Stern) and Leo Klein. He was the second of the three children that the couple had. The family lived relatively comfortably. His father, originally from Hungary, owned a family grocery store in Harlem while his mother was a homemaker who took great delight in visiting her divorced mother’s tailoring shop, helping to give shape to Klein’s love of clothes and design.
