William Blake was born in London on November 28, 1757, to James, a hosier, and Catherine Blake. Two of his six siblings died in infancy. From early childhood, Blake spoke of having visions—at four he saw God “put his head to the window”; around age nine, while walking dathrough the countryside, he saw a tree filled with angels. Although his parents tried to discourage him from “lying," they did observe that he was different from his peers and did not force him to attend conventional school. He learned to read and write at home. At age ten, Blake expressed a wish to become a painter, so his parents sent him to drawing school. Two years later, Blake began writing poetry. When he turned fourteen, he apprenticed with an engraver because art school proved too costly. After his seven-year term ended, he studied briefly at the Royal Academy. In 1782, he married an illiterate woman named Catherine Boucher. Blake taught her to read and to write, and also instructed her in draftsmanship. Later, she helped him print the illuminated poetry for which he is remembered today; the couple had no children. In 1784 he set up a printshop with a friend and former fellow apprentice, James Parker, but this venture failed after several years.
