Born in Brooklyn, John DiGiovanni lived in Valley Stream, Long Island, with his mother. Known for his meticulousness, John detailed his car with a toothbrush. He worked as an East Coast sales manager for Kerr Chemicals.

Heading to a sales call on Feb. 26, 1993, John pulled his car into the World Trade Center’s underground parking garage just before a bomb was detonated there. He was 45 years old.

A memorial fountain was built directly above the blast site on the World Trade Center’s Austin J. Tobin Plaza, which opened to the public two years after the attack on Feb. 23. Inscribed on the 30-foot granite memorial were the names of the six victims. The fountain was destroyed on Sept. 11, 2001, and only a single fragment of the 1993 memorial was recovered from the rubble. It bears part of John’s name.
