The Full Dossier

Early Life and Education

Leonard Norman Stern was born on March 28, 1938, in New York City, to a Jewish family. His father, Max Stern, was a German-born businessman who had emigrated to the U.S. and established Hartz Mountain, a pet supply company. Leonard graduated from New York University (NYU) in 1957 with a Bachelor's degree and later earned an MBA from the Leonard N. Stern School of Business at NYU.

Rise to Success

Stern initially inherited his wealth from his father. He took over the family business, Hartz Mountain, in 1959. He expanded the business before selling the pet supply business for $350 million in 2000. Seven years after joining the company, Stern expanded into the real estate market, acquiring a New Jersey warehouse. His Hartz Mountain firm now owns more than 260 real estate properties, mostly in the New Jersey area. Stern transitioned into real estate, acquiring land and developing properties, eventually growing Hartz Mountain Industries into a major real estate company with a substantial portfolio. By 2000, Stern had transformed the company, focusing exclusively on real estate. The company holds more than 37 million square feet of residential, commercial property in New Jersey, New York and Chicago.
