Getting Started: Essential Question

Why was Los Alamos chosen as an American World War II Heritage City, and what are its similarities and differences to other home front cities?

Quotation to consider:

“An anonymous young scientist at Los Alamos, New Mexico, has in more serious vein summed up the whole issue in a few words that pack an awful wallop:

‘The war just ended,’ he says, is the last victory.’

‘If it is not the last war, it is the next-to-last war.’

Think that one over.”

The Manhattan Project and Los Alamos (Overview) 

By Sarah Nestor Lane 

There are three American World War II Heritage Cities connected to the Manhattan Project: Los Alamos (New Mexico), Tri-Cities (Hanford, Washington), and Oak Ridge (Tennessee). Each had its own part in developing the atomic bombs. 

The purpose of the Manhattan Project was to develop the first atomic bomb during World War II. It was a top-secret research project led by the United States, with the goal of building a powerful weapon before Germany or Japan could. The project aimed to harness the energy of nuclear reactions to create a devastating weapon that would help bring an end to the war.

The Los Alamos National Laboratory sites made important contributions to the Manhattan Project during World War II. The site was in Los Alamos County, in a desert, far away from everything, so they were able to secure the area, work without anyone finding out, and complete experiments. Hispanic ranchers and Native Americans were displaced from their homes and land there. Quickly constructed, large laboratory buildings were scattered along the south side of Ashley Pond. Rows of four-family apartments were built near the mountains. Some raised board sidewalks were made to prevent muddy conditions during winter snow melting and summer monsoons.  

Workers lived in the county and traveled to their work sites. The site played a crucial role in developing and producing the atomic bomb. Plutonium from the Hanford site and uranium from Oak Ridge was used to develop two kinds of bombs at Los Alamos. One was called "Little Boy" and used uranium, and the other was called "Fat Man" and used plutonium. They evaluated two types of bombs: one was the gun method, where they used gun-like technology to bring together smaller amounts of material that wasn't quite enough to explode on its own, and the other was the implosion method. For the implosion method, they used explosives to squeeze a smaller amount of plutonium really tightly until it reached a point where it could cause a big explosion. Scientists combined materials in a way that created a chain reaction, where the splitting of one atom led to the splitting of more atoms, releasing a huge amount of energy.

Los Alamos not only worked on the science and building parts but also on the plans to put everything together. Finally, on July 16, 1945, they did a test with a bomb called the “Gadget,” called the Trinity Test. It was the first time a nuclear bomb was exploded.  All the experiments and hard work in Los Alamos had culminated in this scientific milestone. Although an achievement for the scientists, the two bombs dropped on Japan resulted in thousands of Japanese civilians killed or suffered from injuries or exposure to radiation. With the atomic bombs completed and the war ending, the scientific community at Los Alamos faced a new chapter in history. It is still a national laboratory today. 

“Scientist Believe Atomic Bomb May Cause Unending War” 

LOS ALAMOS, N.M., Oct. 13. (AP)-- Ada Evening News (Ada, Oklahoma), October 14, 1945, p.1 

Foreseeing atomic bombs “thousands of times more powerful” than those dropped on Japan, 400 scientists who developed the weapon at the government’s laboratory asserted in a statement today that to try to keep it from the rest of the world ‘will lead to an unending war more savage than the last.’ 

Released by Dr. Robert R. Wilson, member of the executive council, on behalf of the association of Los Alamos scientists, the statement said: It is certain that nations other than the United States, Great Britain and Canada by research can produce atomic power.  

This nation’s highly concentrated industrial centers make it particularly vulnerable to such a weapon.  

Counter-measures would be ‘extremely difficult and uncertain’ because of the ‘concentrated form of destructive energy’ and ‘the large number of possible methods of delivery.’ 

Advantage would lie with the aggressor. ‘A single heavy attack, lasting a matter of minutes, might destroy the ability of a nation to defend itself further.’ The bomb is ‘a deadly challenge to civilization itself.’ 

‘The use of atomic energy must be controlled by a world authority.’ 

The statement disapproved suggestions that the United States, Britain and Canada assume unilateral control over atomic power development. 

‘Such a policy will lead to an unending war more savage than the last,’ the scientists said. ‘We can not conceive of it leading to a stable, peaceful world.’ 

‘We are convinced,’ the statement continued, ‘that we must cooperate with the rest of the world in the entire development of atomic power, and the use of atomic energy as a weapon must be controlled by a world authority.’ 

Expressing the belief that international control is technically feasible, the scientists said ‘abolition of secrecy in national and international relations may be necessary,’ providing free access to ‘all laboratories, industries and military installations.” 

Excerpt from: “House Report 115-998

“To Direct the Secretary of the Interior to Annually Designate at Least One City in The United States as An ‘American World War II Heritage City,’ and for other purposes” (October 30, 2018) 

“. . .PURPOSE OF THE BILL 

The purpose of H.R. 6118 is to direct the Secretary of the Interior to annually designate at least one city in the United States as an ``American World War II Heritage City''. 

BACKGROUND AND NEED FOR LEGISLATION 

    On December 7, 1941, military forces of the Empire of Japan attacked the U.S. Naval Fleet and ground bases at Pearl Harbor in Hawaii. On December 8, 1941, one day after what President Roosevelt referred to as, ``a date which will live in infamy,'' the United States declared war against the Empire of Japan. Three days later, on December 11, 1941, Japan's ally, Germany, declared war on the United States. Sixteen million Americans, mostly young working-age men, served in the military during World War II, out of an overall United States population of 113 million. 

While an unprecedented number of Americans served in World War II, the country drastically increased its war production on the home front, serving not only the needs of the armed forces of the United States but her allies as well--in what President Franklin Roosevelt called ``The Arsenal of Democracy.'' The combination of millions serving in the military, during a period of necessary and drastic increases in production, led to significant social changes on the American home front. 

The World War II period resulted in the largest number of people migrating within the United States in the history of the country. Individuals and families relocated to industrial centers for good paying jobs out of a sense of patriotic duty. Many industrial centers became ``boomtowns,'' growing at phenomenal rates. One example, the City of Richmond, California, grew from a population of under 24,000 to over 100,000 during the war. . . .”
