The Maps of Bert Twaalfhoven

From the Fordham University Libraries

As a young man, Bert Twaalfhoven and his family lost everything during the bombing of The Hague during World War II. Like his countrymen centuries earlier, Dr. Twaalfhoven immigrated to that land on the Hudson his predecessors knew as New Netherland and he knew as New York.

Dr. Twaalfhoven attended Fordham University and later Harvard Business School. A long career as a venture capitalist and entrepreneur followed, along with a devotion to fostering entrepreneurship in others, the mission of the European Forum for Entrepreneurship Research which he founded in 1987.

Along the way, Dr. Twaalfhoven began collecting 16th, 17th and 18th century maps of his new home. The grateful alum of Fordham donated 22 maps of New Netherland, New Amsterdam and New England to his alma mater. Fordham University has kindly allowed the New Netherland Institute to display these maps in this digital exhibition.

The collection of maps printed from copper plates and in many cases hand-colored hangs in the Reference Room of the Walsh Library at Fordham, where it is accessible to visitors.
