Herb Depke arrived in Hanford in 1943 after his father was transferred by the DuPont Company to work as an expediter during the Manhattan Project. He lived in Richland with his mother and father and in 1945 he moved to Danville, Illinois with his mother while his father was deployed as a Navy Port Director. Although he was only ten years old during the majority of his family's time in Washington, the war and his family's contributions to the war effort were formative in his later life. From 1952 until1962, he was a member of the Navy Reserves.
