This plaque and the visitor center at Humboldt Bay National Wildlife Refuge in California memorialize Richard J. Guadagno. Guadagno was the 38-year-old manager at Humboldt Bay National Wildlife Refuge when he died on September 11, 2001. He and 39 other passengers and crew were aboard United Flight 93 when the hijacked plane bound for San Francisco from Newark, New Jersey, crashed near Shanksville, Pennsylvania. Guadagno was one of almost 3,000 Americans to die at the hands of terrorists that day. In his 17-year career with the U.S. Fish and Wildlife Service, Guadagno worked at several wildlife refuges. He began as a temporary biologist at Great Swamp National Wildlife Refuge in New Jersey. His first permanent Fish and Wildlife Service job was as a wildlife inspector in Philadelphia. Subsequent career moves took him to Prime Hook National Wildlife Refuge in Delaware, Supawna Meadows National Wildlife Refuge in New Jersey, Baskett Slough and Ankeny National Wildlife Refuges in Oregon and, in 2000, to Humboldt Bay National Wildlife Refuge.
