Los Alamos, New Mexico has had several nicknames over the years: Secret City, The Hill, Atomic City, and Site Y. The city exists because it grew up around the Los Alamos Laboratory where the world’s first atomic weapons were secretly developed. Current national security projects continue at the laboratory today. Los Alamos is also the home of one-third of the Manhattan Project National Historical Park. The other park units are in Oak Ridge, Tennessee and Hanford, Washington. We will explain why the park spans three sites later in the post. In the meantime, enjoy your tour of the Los Alamos unit.
Where is It?
The city of Los Alamos sits in the foothills of the Jemez Mountains about 33 miles northwest of New Mexico’s capitol city of Santa Fe. The visitor center is located at 475 20th Street and is a good place to begin the self-guided walking tour of the historic sites and museums. The park is free to visit, although the Los Alamos History Museum requires an admission fee. Click here to access the park’s website.
The History Begins With the Los Alamos Ranch School
Ashley Pond, Jr., a Detroit, Michigan native and one of Teddy Roosevelt’s Rough Riders during the Spanish American War, founded the Los Alamos Ranch School in 1917. Pond’s love of the outdoors, ranching, and New Mexico’s fresh air are what drove him to establish the prep school that catered mainly to the sons of wealthy east coast families.
The government paid almost a half million dollars for the school and 50,000 acres of surrounding land. In December 1942, the school’s director received notice that the school was to be surrendered to the government as a matter of utmost importance in the prosecution of the war.
The Alamos Ranch School closed after its last graduation in January 1943, and the military moved in. Nine months later, a secret laboratory had been built and work was underway for the development of atomic weapons. Along with it a secret city was quickly springing up for the project’s workers and their families. Meanwhile, Hanford, Washington and Oak Ridge, Tennessee were also becoming top secret worksites for other phases of the Manhattan Project.
Our walking tour began at the park’s visitor center. The delightful lady working in the office gave us information about the historical sites and also told us about the filming sites of the (then) upcoming movie Oppenheimer. Click here to view a YouTube movie trailer.
We then walked down the street called Bathtub Row. The homes on Bathtub Row were originally built to house the Ranch School’s faculty. With Project Y’s new homes and dormitories – hastily built for the purpose of merely lasting until the end of the war – only having showers, the community began referring to the street where some of the top officials and scientists lived as Bathtub Row. You guessed it, they had the only bathtubs in town, and the name stuck.
Trivia: Eighteen of the scientists who worked on the Manhattan Project in Los Alamos under the direction of Dr. J. Robert Oppenheimer were Nobel Prize winners. Oppenheimer was a Nobel nominee on three different occasions, however, he never won.
As part of our walking tour, we visited the Los Alamos History Museum and the Bradbury Science Museum where we learned a lot about the history of Los Alamos and the incredible efforts that went into the Manhattan Project. Below are some historic photos that are relevant to the testing of the first atomic weapon.
It’s hard to believe that less than a month after the Trinity test, a uranium bomb called Little Boy exploded over Hiroshima, Japan. Fat Man, a bomb fueled by plutonium exploded over the Japanese city of Nagasaki three days later. The bombings, while unimaginably devastating, effectively brought an end to World War II.
Trivia: The fireball created by the Trinity test carried up sand that melted in the mushroom cloud. The melted sand then dropped back to earth where it solidified into a new manmade mineral. Scientists dubbed the new mineral trinitite.
Three Sites, One Goal
Oak Ridge, Tennessee was home to another secret city that was built for the purpose of enriching uranium to fuel nuclear weapons and also to produce small amounts of plutonium. Interestingly, most of its 50,000 workers did not know they were working on components of the first atomic weapons. Today Oak Ridge is still home to the Oak Ridge National Laboratory, the largest laboratory in the US.
Another large industrial complex was built in Hanford, Washington for the purpose of producing plutonium. According to the National Park Service, the complex had huge production-scale reactors, chemical separations plants, and fuel fabrication facilities. The Hanford site employed approximately 51,000 workers.
Air transportation was too risky for the transport of plutonium and uranium. Therefore, the elements produced by the Oak Ridge and Hanford laboratories were delivered to Los Alamos by inconspicuous, unguarded “traveling salesmen” who hand carried special luggage via the railroad.
Trivia: At its height of employment in 1944, approximately 129,000 people worked on the secretive Manhattan Project, and of those 84,500 were construction workers.
More History Around Town
The Manhattan Project was successful due to a massive effort that spanned just 27 months from start to finish and included thousands of military and civilian laborers who worked toward a common goal although they were located in three separate sites across the country.
