Schwartz is the business half of Calvin Klein Inc.’s leadership, and without his industry savvy, Klein’s popular fashion designs could not have become so successful. Schwartz’s attentive management style allowed the company to purchase its long time manufacturer Puritan Inc. for $612 million, only $105 million of which was borrowed. Deals like this were typical of Schwartz’s skill and because of it Calvin Klein grew to have sales of over $1 billion by 1984.
