An 87-year-old man jumped to his death yesterday morning from his apartment in The San Remo on Central Park West, the NYPD confirmed. A police spokesperson would not release his name, but The Post has identified the man as multimillionaire philanthropist Robert W. Wilson, a "former Wall Street hedge fund titan" who has donated most of his fortune to the World Monuments Fund, the Nature Conservancy, the Environmental Defense Fund and the Wildlife Conservation Society.

Wilson’s friend, Stephen Viscusi, tells the tabloid Wilson suffered a stroke a few months ago, adding that "he always said he didn’t want to suffer, and when the time came, he would be ready."

Police sources say Wilson left a suicide note behind, and cops called to the scene found his body in a rear courtyard shortly before 11 a.m. Wilson had no children, and his only marriage ended in divorce after 35 years.

If someone you know exhibits warning signs of suicide: do not leave the person alone, remove any firearms, alcohol, drugs or sharp objects that could be used in a suicide attempt, and call the U.S. National Suicide Prevention Lifeline at 800-273-TALK (8255) or take the person to an emergency room or seek help from a medical or mental health professional.
