Anderson's tribute to Reed was published Thursday in a suburban New York newspaper. Reed died Sunday at 71 from complications following a liver transplant.
Anderson wrote that she brought Reed from the hospital to their home in Springs, N.Y., one week earlier. She says he "spent his last days here being happy and dazzled by the beauty and power and softness of nature."
Anderson says Reed was a "tai chi master" who was practicing its forms with his hands when he died.
She signs the letter as "his loving wife and eternal friend."
