William Griggs was a medical doctor in Salem Village, Massachusetts. He is best known as the doctor who diagnosed the Salem Villagers as possessed, during the time of the Salem witch trials.[1] Griggs was in charge of diagnosing and determining how "much" of a witch they were. Griggs claimed that the "afflicted" girls were "under an Evil hand" (most likely referring to the Devil).
