    Leonard Stern is the chairman and CEO of the privately owned Hartz Group.

    The former head of a pet-supplies company he inherited in 1959, Stern made his first foray into real estate in the late 1960s, when he bought a huge portion of the then-undeveloped Meadowlands in New Jersey for $10 million. The investment paid off more than twenty-fold.

    From there he entered the media business, purchasing the Village Voice in 1986 and a few other alternative weeklies before selling them all in 2000 and focusing on real estate.

    The Hartz Group's signature properties include 667 Madison Avenue, the Soho Grand and the Tribeca Grand.

    Stern donated tens of millions to New York University in the late 1980s and early 1990s, and the university's business school is named after him.
