TEANECK - A professor from Fairleigh Dickinson University is making a donation to the National Sept. 11 Memorial & Museum.

The donation is of pictures of the World Trade Center, when the towers still stood. Professor Hanson went up in a helicopter to take the photographs of Manhattan in 1993 and 1994. He had no idea his high-resolution images of the gleaming World Trade Center would become invaluable archive material.

Professor Hanson used a specially built, wide-angle camera to take photos of the New York City skyline, one dominated by the twin towers.

Hanson is donating 20 of his images to the museum. He hopes it could help build exhibits and help future generations understand the World Trace Center's soaring prominence.
