Gertrude Stein recalled that on the copy of her final exam for a class taught by William James she wrote, “Dear Professor James, I am so sorry but really I do not feel a bit like an examination paper in philosophy today.” She then left the room. The next day a note arrived from Professor James that said, “Dear Miss Stein, I understand perfectly how you feel. I often feel like that myself”—and then awarded her the highest mark in the course.

Joseph Conrad recalled, “It was in 1868, when nine years old or thereabouts, that while looking at a map of Africa of the time and putting my finger on the blank space then representing the unsolved mystery of that continent, I said to myself, with absolute assurance and an amazing audacity which are no longer in my character now, ‘When I grow up I shall go there.’”

“I went sailing up to Great Point, which is fourteen miles. It was fine and rough so we went out in the open ocean and shipped water grandly. I have bought a large swordfish sword for the agassiz of an old salt by the name of Judas,” Ernest Hemingway wrote to his brother Marcelline in one of his earliest known letters, shortly after his eleventh birthday, in 1910.

In 1385 Robert Braybroke, bishop of London, recommended excommunication for boys who “play ball inside and outside the church [St. Paul’s Cathedral] and engage in other destructive games there, breaking and greatly damaging the glass windows and the stone images of the church.”

Phia Rilke’s infant daughter had died a year before she gave birth to her son. She named him René Maria—sometimes referring to him as Fräulein, Margaret, and Sophie—and gave him dolls to play with, dressing him as a girl until he was six years old. The poet did not start using Rainer instead of René until he was in his twenties.
