After graduating from Harvard Business School in 1965, Kraft, a Massachusetts native, began his career with the Rand-Whitney Group, a paper and packaging company owned by his father-in-law.
In 1968, Kraft acquired a controlling stake in the company through a leveraged buyout. Four years later, he founded International Forest Products, which trades forest product commodities, including containerboard and pulp, around the world.
Kraft grew his paper and packaging conglomerate to become one of the largest exporters in North America.
