HISTORY MOMENTS The Idaho State Historical Society reports that during this week in history: Author Helen Keller died on June 1, 1968, at the age of 88. Helen, blind and deaf, graduated from Radcliffe in 1904 with honors and lectured throughout America, Europe and Asia, raising fund to the training of the blind and promoting other social causes. During the Civil War when the mines in the Boise and Owyhee Mountains were producing gold and silver for the war effort, the War Department decided to establish a post along the Boise River. Major Pinkey Lugenbeel left Fort Vancouver, Washington Territory, with Company D, G, and I of the 1st Washington Territorial Infantry on June 1, 1863, charged with the responsibility of identifying a suitable site. They arrived later that month at what would become Fort Boise, at the base of the Boise foothills. On June 2, 1924, Congress granted U.S. citizenship to all American Indians. A disaster unparalleled in Idaho's history occurred on June 5, 1976, when the newly constructed Teton Dam collapsed as its reservoir neared capacity. Thousands of Madison County residents were left homeless and damage across a four-county area exceeded $500 million. On June 6, 1944, nine army divisions from the United States, Britain and Canada landed on five beaches along 50 miles of Normandy coast. Over 5,000 ships, 11,000 airplanes, and 156,000 service men launched the largest invasion in history to begin the drive to free occupied Europe from the grip of Nazi Germany. The event is now known as D-Day.
