I remember meeting her at the bedside of a dear, very ill friend. I backed her up as she ferociously took on doctors and nurses to make sure he had the very best care. She fought that hard for all her causes. Passionate and tireless. And how she loved being 'Caroline'!!"
McCay studied with Lew Strasberg in New York and later assisted in setting up his west coast acting studio, which was attended by such luminaries as Marilyn Monroe, James Dean and Paul Newman.
From 1951 to 1955 McCay starred on CBS soap opera Love of Life as Vanessa Dale, whose battles with sister Meg were the center of the show's early years. Her later daytime roles included Susan Garret on The Young Marrieds and Iris Fairchild on General Hospital.
