Last September, Buck anonymously gave the health system $10 million toward construction of a new patient tower, which will be named for Buck and his late wife, Carmen Lúcia, who died in 2003. The now-completed eleven-story facility has a 35-bed medical/surgical patient-care floor, a 30-bed state-of-the-art critical care unit, and a 40,000-square-foot emergency department featuring a streamlined triage area, a dedicated imaging center, and a specialized pediatric unit.
At the time of that gift, Buck also committed an additional $20 million to WCHN, contingent on its meeting its $50 million campaign goal. He also agreed that if and when the campaign goal was met, he would allow his name to be revealed. Funds raised through the campaign, which was about $10 million short of its goal when Buck made his pledge, will be used to invest in facilities, technologies, and research at Danbury Hospital, New Milford Hospital, and WCHN's Biomedical Research Institute.
Buck told the Wall Street Journal that it was his late wife's idea to support Danbury Hospital, which previously received gifts from the couple totaling $8 million to fund a chair in surgery and a robotic-surgery center. While Buck’s latest gift came after he received "very good treatment" at Danbury Hospital, he denied making the donations out of gratitude for his care. "I don't give back," he told the Journal. "I give."
