Van Gogh's mother came from a prosperous family in The Hague, and his father was the youngest son of a minister. The two met when Anna's younger sister, Cornelia, married Theodorus's older brother Vincent (Cent). Van Gogh's parents married in May 1851 and moved to Zundert. His brother Theo was born on 1 May 1857. There was another brother, Cor, and three sisters: Elisabeth, Anna, and Willemina (known as "Wil"). In later life Van Gogh remained in touch only with Willemina and Theo. Van Gogh's mother was a rigid and religious woman who emphasised the importance of family to the point of claustrophobia for those around her. Theodorus's salary was modest, but the Church supplied the family with a house, a maid, two cooks, a gardener, a carriage and horse, and Anna instilled in the children a duty to uphold the family's high social position.
Van Dyke left high school in 1944, his senior year, intending to join the United States Army Air Forces for pilot training during World War II. Denied enlistment several times for being underweight, he was eventually accepted for service as a radio announcer before transferring to the Special Services and entertaining troops in the continental United States. He received his high school diploma in 2004 at the age of 78.
