In an article for the St. Louis Dispatch, Anna George De Mille shared some of her private recollections of her father.  Among the memories she shared was the following:

“Nobody could quiet me but father, nobody could soothe my imaginary fears like him…He used to take me in his study and show me pictures of birds.  I don’t know what kind of birds they were–they seemed to be doves, red and blue doves.  I suppose it was their bright colors that attracted me.  I was too young to speak, but it seems to me if I could find the books they were in I could turn to the very page.”
