The company was started in the Chelsea section of New York City by Nathan Greenman, a Hungarian immigrant entrepreneur who had a knack for seeing the need of a product and taking the next step in producing it. As the story is told, being a new venture with minimal cash, he was fairly conservative with the Company's spending. When asked what the name of his new company would be, he turned to see the name and sign hanging of an existing company sharing the warehouse space with him. Figuring he could save the money by not having to purchase a new sign, Knickerbocker Steel Partition Co., Inc. was established.

With increasing sales, the company quickly moved to 91 Lorimer Street, Brooklyn. Succession of ownership occurred in 1960 bringing two employees together in partnership that lasted until 1987 when Joe Abbate passed away after a long battle with cancer. The partners fulfilled a dream by building a new manufacturing plant on the south shore of western Long Island, moving the company to its present location: 193 Hanse Ave., Freeport, NY in 1969.

David Markbreiter remains as an intregral part of the day to day operations of what has now become a family owned and operated establishment with three additional stocking facilities throughout the United States and a distribution network that spans worldwide.

The success of the business is directly attributed to the dedication and hard work of all its employees from the union factory staff to the front office personnel. Together, as one large family, Knickerbocker Partition Corp. is poised for the twenty-first century; bringing a high standard of service and quality products to the commercial market place.
