Most people don't know the true story of the little boy who came to be known as Douglas Craig. He was found wandering around the streets of Washington, D.C. He could not hear or speak. It is said that a man named Craig found the little boy and took him to Dr. E. M. Gallaudet at Gallaudet College. Dr. Gallaudet gave him the first name of Douglas, and the last name of Craig, after the man who found him. The little boy became Douglas Craig. Dr. Gallaudet placed Douglas in the Kendall School, and he stayed there until he was old enough to work. He spent his life working in and around the halls of Gallaudet. Douglas grew to become a tall, strong man. He had many duties, such as picking up mail at the post office, mowing grass, raking leaves, tending the flower beds, raising and lowering the heavy drop curtain on the stage for plays in the chapel, and carrying notes from the boys to the girls. Douglas actively sought a wife during his life at Gallaudet. It is said that he asked all of the black cooks in the college kitchen to marry him. For a time, he courted a black woman from Baltimore. Later in life, he married a black deaf woman from Washington.
