The United States in late 1941 established a secret program, which came to be known as the Manhattan Project, to develop an atomic bomb, a powerful explosive nuclear weapon. The aim of the project, directed by physicist J. Robert Oppenheimer, was to build an atom bomb before Germany did.
US physicist Robert Oppenheimer and General Leslie R. Groves served as directors of this project, which recruited some of the best US scientists, engineers and mathematicians. A number of European scientists, including Albert Einstein, Enrico Fermi, and Leo Szilard, also participated in the Manhattan Project.

For centuries, the Hanford area bordering the Columbia River was home to several tribes of Native Americans. Remnants, artifacts, and burial sites associated with historical Native American activity are found throughout the Site and are protected by law. The mid-1800’s brought pioneers and settlers to the mid-Columbia. The small towns of White Bluffs and Hanford sprang up to support the farms and ranches of early residents. When the War Department decided to locate portions of the Manhattan Project in this part of Washington, it also decided that work to develop atomic weapons had to be done in secret. Subsequently, in early 1943, all of the residents of White Bluffs and Hanford were told to evacuate their homes and abandon their farms, and were given just 30 days and a small amount of money to do so.
