In November 1921 Carl Sandburg’s 10-year-old daughter Margaret fell asleep in class and was diagnosed with nocturnal epilepsy. Her mother rushed her to Battle Creek Sanitarium, where her condition would be treated with fasting. Sandburg wrote to her:

Dear Margaret,

This is only a little letter from your daddy to say he thinks about you hours and hours and he knows that there was never a princess or a fairy worth so much love. We are starting on a long journey and hard fight — you and mother and daddy — and we are going to go on slowly, quietly, hand in hand, the three of us, never giving up. And so we are going to win. Slowly, quietly, never giving up, we are going to win.

Daddy

They did. Margaret’s weight plummeted, but she recovered and went on to edit many of her father’s works. In 1953 Sandburg wrote to a friend, “Margaret has become widely read, a scholar who often surprises me with her erudition, knows the Bible and Shakespeare better than I do.”
