David Liederman, whose confections redefined the chocolate chip cookie and whose chain, David’s Cookies, grew to more than 100 stores nationwide, died on July 4 in Mount Kisco, NY. He was 75.

The unique feature of Mr. Liederman’s innovative version of the chocolate chip cookie was that it was not made with standard Toll House chocolate chips, but was studded with irregular pieces of dark

Swiss Lindt chocolate. He called his cookies chocolate chunk.

He opened his first cookie store, David’s Cookie Kitchen, on Second Avenue and 53rd Street in Manhattan in 1979. A chain of more than 100 David’s Cookies stores opened nationwide and in Japan. He sold David’s Cookies to Fairfield Foods in New Jersey in 1995 and retired from the company. He valued his cookie business at about $35 million in mid-1980s (about $102 million in today’s currency).

He also fronted several restaurants, including Manhattan Market, Chez Louis, Broadway Grill, Television City, and Restaurant Luna in Mount Kisco.
