Before 1942, the area around Black Oak Ridge was a peaceful rural farming area. It only became a city when the U.S. Government chose it as the production site for the Manhattan Project and the development of the atomic bomb. Although the area was not densely populated, the people who did live there were evicted from their homes and given as little as two weeks to evacuate.
A large number of people were needed to work on the military project, so a town was built for the workforce and their families. Jackson Square was the original commercial site of Oak Ridge, and was surrounded by housing. By 1945, the population swelled to 75,000. The town included 300 miles of roads, ten schools, seven theaters, 17 restaurants, and 13 supermarkets.
It was only after the atomic bomb was dropped on Hiroshima, Japan in 1945 that many of the workers realized what they had been working on. Oak Ridge is no longer a military town, and only has a population of about 27,000. Efforts are currently underway to revitalize and preserve Jackson Square.
Here's the back of the card, sent to Mrs. Addie Wolcott in Miami, Florida in 1955.
The message reads:
Dear Addie: I received your letter but have little time to write these days. The children are very good, but do need a lot of attention. It keeps us both busy. Do hope the hurricanes keep on passing us by.
