The Men Who Made

The Atomic BombSlide2

“Your

children who follow you in later generations and foreigners who come from distant lands will see the calamities that have fallen on the land and the diseases with which the LORD has afflicted it. The whole land will be a burning waste of salt and sulfur — nothing planted, nothing sprouting, no vegetation growing on it. It will be like the destruction of Sodom and Gomorrah, Admah and Zeboyim, which the LORD overthrew in fierce anger.”   - Deuteronomy 29:22-23

THIS COULD HAVE BEEN A BIBLICAL STORYSlide3

THE REAL STORY IS ABOUT JEWISH

SCIENTISTS MAKING WEAPONS OF MASS DESTRUCTION

Albert Einstein Leo Szilard Robert OppenheimerSlide4

Definition From Wikipedia

- A weapon of mass destruction (WMD or WoMD) is a nuclear, radiological, chemical, biological or other weapon that can kill and bring significant harm to a large number of humans or cause great damage to human-made structures (e.g. buildings), natural structures (e.g. mountains), or the biosphere.Slide5

Early WMDs –

Chemical weapons, such as Greek Fire, were in use as early as 673 CE. Even earlier legend says that Archimedes had developed a “heat ray” using mirrors circa 250 BCE.Slide6

H. G. Wells – Science Fiction

Heat Ray – War of the Worlds (1898)Tanks – The Ironclads (1903)Aerial Combat – The War in the Air (1907)Poison Gas (Black Smoke) – War of the Worlds (1898)

Biological Weapons – War of the Worlds (1898)Atomic Bomb – The World Set Free (1914)Slide7

WMD - World War I

Fritz Haber had won the 1918 Nobel Prize in chemistry for his invention of the Haber-Bosch process, a means of synthesizing fertilizer that is credited with saving Europe from famine caused by depleted soil. During the First World War, Haber turned his genius in a different direction – the development and production of poison gases, most notably chlorine gas. He is considered the “father of chemical warfare.”

After the war, Haber continued his research and teaching at the Kaiser Wilhelm Institute in Berlin. One of his students would develop the Zyklon-B gas, originally intended as an insecticide, that would be used so infamously in the concentration camps.Most ironically, Haber had been born into a Jewish family from Breslau, Poland.Slide8

Einstein

At the Kaiser Wilhelm Institute, Haber would share the podium with another brilliant Jewish scientist – Albert Einstein.Born in Germany to non-observant Jewish parents, Einstein had traveled with his family to Italy. He would later attend school in Switzerland and, after a time spent working in the patent office, would himself become a professor of physics. In 1905, the so-called “miracle year” Einstein would publish four papers, each considered to be ground-breaking.

In 1914, he would return to Germany, where he would be appointed director of the Kaiser Wilhelm Institute and a professor of the Humboldt University of Berlin. Because of his stature in the field, Einstein was freed from teaching duties, but he both attended and gave lectures.Slide9

The Germans

Max Planck, one of the original founders of the Kaiser Wilhelm Institute (which would be renamed the Max Planck Institute for Physics after the war) Planck was the originator of quantum theory and won the Nobel Prize in Physics in 1918.

Max von Laue had won the Nobel Prize in Physics in 1914 for his work on the diffraction of X-rays by crystals. He would succeed Einstein in the position of Director of the Institute. He was also a staunch opponent of National Socialism.

Werner Karl Heisenberg also worked on quantum mechanics and also served as the Director of the Institute in the years after the war. The degree to which Heisenberg willingly participated in Germany’s war-time atomic research and his relationship with Danish physicist Niels Bohr are matters that are debated even today.Slide10

The Students – Leo Szilard

Brilliant teachers attract brilliant students. People came from all over Europe to study physics at the Kaiser Wilhelm Institute; perhaps none was more brilliant than Leo Szilard, a young man from Hungary. First an engineering student at

the Palatine Joseph Technical University in Budapest, his studies were interrupted by military service during World War I. After the war, in 1919, he left Hungary to attend the Technische Hochschule (Institute of Technology) in Berlin. He grew bored with engineering and in 1920 transferred over to study physics.Leo was not only a student of Einstein‘s, but also a collaborator. By 1926, the two of them had filed a patent for the Einstein-Szilard Refrigerator (also known as the Einstein Refrigerator)

which has no moving parts,

operated

at constant pressure, and

required

only a heat source to operate.

Szilard was known for his dry sense of humor and his abrasive personality. Because he was not well-liked (although he was respected by his colleagues) he often did not receive the credit that he was due. It was said of him that he “

was the most brilliant scientist never to have won a Nobel Prize

.” But he was not only brilliant, he was a man that changed the course of history.

The Hungarian Quartet

Eugene Paul Wigner – Four years younger then Leo Szilard, Wigner followed an almost identical path in his early years. Also born in Budapest, Wigner attended first the Technical University and then the Kaiser Wilhelm Institute. Not only a brilliant physicist, Wigner was also a brilliant mathematician. Wigner’s theorem is considered instrumental in the mathematical analysis of quantum physics. As an aside, Wigner’s younger sister Margit married physicist Paul Dirac.

John von Neumann was born Neumann János Lajos in Budapest, although his parents used his Hebrew name of Yonah. Not only was he a brilliant physicist, he also distinguished himself in mathematics, economics, computer science and statistics

. He published over 150 papers during his life. His last work, written while he was in the hospital, would be published as a book entitled

The Computer and the Brain.

Edward Teller

was the youngest of the group but

brilliant in his own right. He made numerous contributions in several areas of physics

,

including nuclear

and molecular physics, spectroscopy

and

surface

physics. He is also considered one of the inspirations for Stanley Kubrick’s character

Dr. Strangelove.Slide12
Slide13

Roentgen and X-Rays

Why Germany and what was so interesting about atomic physics at this particular time? In 1895, Wilhelm Roentgen was conducting a particular experiment to determine the effects of passing an electrical discharge though a vacuum tube covered in aluminum with only a thin window to allow the cathode rays to escape. Roentgen had added a protective covering of cardboard to protect the aluminum; this should have blocked all light from coming out. But he noticed a fluorescent effect on a small cardboard screen painted with barium platinocyanide when it was placed close to the aluminum window. He had discovered X-Rays also known as Roentgen

Rays, an achievement that would earn him the first Nobel Prize in Physics in 1901. The discovery of these X-Rays would not only change medicine, but would greatly help in the understanding of the structure of the atom.Slide14

France – the Curies

Marie Skłodowska

Curie was born in Poland, part of a family known for its illustrious academic accomplishments. In 1891, partially due to a failed romantic relationship, she moved to France to study at the Sorbonne. In 1893, she earned a degree in physics. In 1894 she would add a degree in mathematics. That same year she met her future husband and research partner, Pierre Curie.She began to study the problem of how a specific chemical, uranium, was producing energy similar to X-rays, without interaction from outside sources. The energy appeared to come from the uranium atoms themselves. But how could this be when the atom had been defined as the smallest part of matter and indivisible?

Curie’s research would result in the discovery of two new elements, polonium and radium and of the theory of

radioactivity

, a term that she would coin. Her work required a reconsideration of how we thought of the atom.Slide15

Denmark - Niels Bohr

Niels was born Denmark, in 1885. Son of Christian Bohr, a devout Lutheran and Ellen Adler Bohr, who came from a wealthy Jewish family.Working with New Zealand physicist Ernest Rutherford, the two would develop the Rutherford-Bohr model of the atom:

A “planetary” style model, electrons were in orbits around the nucleus.Electrons can only orbit stably, without giving off energy or radiating, in certain orbits, called by Bohr “stationary orbits.”. Electrons can only gain or lose energy by moving from one of these stationary orbits to another.

Bohr’s work was based on Planck’s theory of radiation, and was more evolutionary than revolutionary. Bohr’s model had several errors and has since been refined; however it provided a framework for what came next.Slide16

Italy- Enrico Fermi

Born in Rome in 1901, Fermi was interested in electrical and mechanical toys from a very young age. Perhaps this was only natural as his father held a senior position in the Ministry of Railways while his mother was a teacher

. As a physicist he would distinguish himself by exceling both theoretically and experimentally.Although Fermi was baptized in accordance with the wishes of his grandparents, his immediate family was not religious and he would consider himself an agnostic. In 1928, he would marry Laura Capon, a science student that he met at university. Laura was Jewish. They would have two children.

In 1928, Fermi published

Introduction to Atomic Physics.

As a teacher, Fermi liked to gather colleagues and graduate students together to go over problems. He began to generate international interest and in 1932 German physicist Hans Bethe came to collaborate with Fermi.

In 1934, Fermi began his most important work with the atom, discovering that nuclear transformation could occur in nearly every element. One of the elements' atoms he split was uranium.Slide17

Rise of Fascism

In 1919, Benito Mussolini formed the Fascist movement in Italy. By 1922 he would become Prime Minister. In 1919, a young German intelligence officer was sent to infiltrate the German Workers Party or DAP. While attending a meeting, he would become so impressed with the ideas of DAP organizer Anton Drexler (anti-Semitism, anti-capitalist, anti-Marxist and nationalist) that he would join DAP, becoming member 555. By 1920 he had taken over the role of propaganda officer and renamed DAP the

Nationalsozialistische Deutsche Arbeiterpartei better known as the Nazi Party.By 1933, this man, Adolf Hitler by name, would become Chancellor of Germany.Slide18

The Flight of the Scientists

67 days after taking power, Hitler strips “non-Aryans” of teaching positions.Einstein's theory of relativity declared to be 'Jewish world-bluff.' Hans Bethe is in the middle of teaching when a student informs him he has been fired. He is one of the many that will flee to England.In May of 1933. Einstein’s books are burned. A German magazine lists him as an enemy along with the phrase “not yet hanged.” He flees to England, then on to the U.S.

Leo Szilard does his best to get other scientists out and to find places for them, staying in Germany through much of 1933. By his account he himself catches the last train out to Hungary. The next day the same train was being stopped by the German military. Slide19

The “In-Between” Days

Einstein arrives in America in October 1933 and takes a position at the Institute for Advanced Study located in Princeton, NJ.At this time and continuing until after the end of WW II major universities including Harvard, Yale and Princeton still have Jewish quotas in place.In 1934 Leo Szilard takes a position at St. Bartholomew’s Hospital in London in order to get access to radioactive materials.While crossing a busy London street in 1936, Szilard conceived of the idea of a nuclear chain reaction. *Slide20

Research in Manhattan

January 2, 1938 Leo Szilard arrives in the U.S.; begins series of lectures.Niels Bohr sends word that the Germans (Otto Hahn, Fritz Strassmann, Lise Meitner, Otto Frisch) have developed nuclear fission using uranium.Unable to convince anyone (esp. Fermi) that uranium could sustain a chain reaction, Szilard starts experimenting at Columbia for proof.Canadian born Walter Zinn joins Szilard.

Using a radium-beryllium source to bombard uranium with neutrons, the experiment proved that a chain reaction was possible.Slide21

Einstein’s Letter to FDRSlide22

Key Points of the Letter

“In the course of the last four months it has been made probable — through the work of Joliot in France as well as Fermi and Szilárd in America — that it may become possible to set up a nuclear chain reaction in a large mass of uranium, by which vast amounts of power and large quantities of new radium-like elements would be generated. Now it appears almost certain that this could be achieved in the immediate future.”“This new phenomenon would also lead to the construction of bombs, and it is conceivable — though much less certain — that extremely powerful bombs of a new type may thus be constructed. A single bomb of this type, carried by boat and exploded in a port, might very well

destroy the whole port together with some of the surrounding territory.” “I understand that Germany has actually stopped the sale of uranium from the Czechoslovakian mines which she has taken over. That she should have taken such early action might perhaps be understood on the ground that the son of the German Under-Secretary of State, von Weizsäcker, is attached to the Kaiser-Wilhelm-

Institut

in Berlin where some of the American work on uranium is now being

repeated.”Slide23

…and so it begins.

FDR to Brigadier General Edwin M. "Pa" Watson "Pa, this requires action!”In Oct. of 1939, Szilard, Teller and Wigner meet with the newly formed Advisory Committee on Uranium.Initial budget for the project is $6,000.Experiments continue using graphite as a moderator.Breakthrough comes when Szilard meets with the National Carbon Company.Slide24

The

Metallurgical LaboratoryEstablished by the National Defense Research Committee on Dec. 6th, 1941.

The next day the Japanese attack Pearl Harbor.Headed by Arthur Compton, work moves to the University of Chicago.Goals are to produce a chain reaction (Jan. 1943) then a nuclear reactor to manufacture plutonium (Jan. 1944) then finally an atomic bomb (Jan. 1945)

At first, Szilard is excluded. But this doesn’t last.

In January of 1942, Szilard joins as a research assistant before being promoted to chief physicist.

Szilard was the man with the ideas, while Fermi was the experimentalist.

Chicago Pile-1

1st Nuclear reactor - 45,000 graphite blocks weighing 400 tons; 6 tons of uranium metal; 50 tons of uranium oxide. Build under the abandoned football field at the University of Chicago.As a failsafe, Walter Zinn had fashioned a cadmium rod that would drop ending the reaction – Zinn’s

Infernal Pile.“The reaction is self-sustaining. The curve is exponential.” – Enrico FermiSlide26

Believing the Unbelievable

On Dec. 13th, 1942, America’s most popular newsman took to the airwaves with "Millions of human beings, most of them Jews, are being gathered up with ruthless efficiency and murdered...It is a picture of mass murder and moral depravity unequaled in the history of the world. It is a horror beyond what imagination can grasp...There are no longer 'concentration camps' - we must speak now only of 'extermination camps'."Slide27

Robert Oppenheimer

Born in NYC on April 22, 1904 to wealthy Jewish parents.Attended Felix Adler’s Ethical Culture Society School before going on to Harvard. Develops colitis and is sent to New Mexico. Returns and graduates summa cum laude in three years.Graduate work at Christ’s College Cambridge, then to the University

of Göttingen to study under Max Born. Meets Heisenberg, Dirac, Fermi, Pauli and Teller.Teaches at Harvard, Caltech and Berkeley. In May of 1942, he joins the atomics project and is appointed "Coordinator of Rapid Rupture.“ Immediately he hosts a session on bomb theory. Edward Teller is one of the attendees.

When Gen. Leslie Groves is appointed director of the Manhattan Engineer District, he selects Oppenheimer to head the secret weapons project.Slide28

Los Alamos

In 1942, Groves and Oppenheimer were looking for a secure site to continue the work. Originally they looked at a site near the ranch where Oppenheimer had spent part of his youth. Ultimately they picked a site on a flat mesa, not too far from Santa Fe. The facility was built on what had been the Los Alamos Ranch School. Slide29

Oak Ridge, Tennessee

A number of locations were established to provide the scientists at Los Alamos with the materials they needed. The plant at Oak Ridge, Tennessee was so big that it was sometimes called “the secret city.” More than 25,000 workers were involved in the construction. This building, the K-25, was a mile long, in the shape of the letter “U”. It was there that uranium was transformed to make it “weapons grade.” Slide30

Letter From Gen. Groves to Henry StimsonSlide33

The Decision

Pres. Franklin D. Roosevelt dies April 12, 1945.Harry S. Truman succeeds him.Truman’s diary of July 17th, 1945 records a meeting with Stalin and also references the atomic bomb.Diary of July 30th, 1945 records Truman authorizing Stimson to release

a public statement about the use of the bomb.No actual signed order has ever been found.Slide34

Truman’s Handwritten NotesSlide35

Little Boy

Oppenheimer originally thought of a “gun” approach to making a bomb. Using conventional explosives as propellant, a uranium projectile that is of sub-critical mass is fired at a uranium target, also of sub-critical mass. The combination of the two becomes critical and a chain reaction ensues. Slide36

Fat Man

Fat man was an implosion type device. A sub-critical core of plutonium is surrounded by high-explosive in such a way that it explodes inwards. When the explosive goes off, the plutonium is crushed into a critical mass.Slide37

The Aftermath

Captain Robert Lewis, co-pilot of the Enola Gay, meets Kiyoshi Tanimoto, a Hiroshima survivor on the American gameshow This Is Your Life in 1955. When asked for his recollections of the fateful day, Lewis referred to the official log, “I wrote down the words, "My God, what have we done

?””Slide38

The Germans – A Fly On the Wall

KORSCHING: That shows at any rate that the Americans are capable of real cooperation on a tremendous scale. That would have been impossible in Germany. Each one said that the other was unimportant.HEISENBERG: We wouldn't have had the moral courage to recommend to the government in the spring of 1942 that they should employ 120,000 men just for building the thing up. WEIZSAECKER: I believe the reason we didn't do it was because all the physicists didn't want to do it, on principle. If we had wanted Germany to win the war we would have succeeded! HAHN: I don't believe that, but I am thankful we didn't succeed.

HEISENBERG: Well, that's not quite right. I would say that I was absolutely convinced of the possibility of our making a uranium engine, but I never thought we would make a bomb, and at the bottom of my heart I was really glad that it was to be an engine and not a bomb. I must admit that.Slide39

Epilogue and Regrets:

Albert Einstein to Linus Pauling – “I made one great mistake in my life—when I signed the letter to President Roosevelt recommending that atom bombs be made; but there was some justification—the danger that the Germans would make them ..” (1954)Leo Szilard – In 1945, he drafted the Szilard Petition, advocating for an observed demonstration of the atomic bomb (not to be used in war.) After the war, he switched careers to biology. In 1960, diagnosed with bladder cancer, he underwent Cobalt-60 treatment, which he had designed. He died in his sleep in 1964.Enrico Fermi – After the war he joined

Oppenheimer on the General Advisory Committee, which advised the Atomic Energy Commission on nuclear matters and policy. He opposed the development of the hydrogen bomb and testified on behalf of Robert Oppenheimer. Died of stomach cancer at age 53.Slide40

Continued:

Robert Oppenheimer – First chairman of the General Advisory Committee of the Atomic Energy Commission in 1947. In 1954, while working as a consultant, Oppenheimer was called to testify before a security committee. Despite “naming names” he lost his security clearance. He joined fellow scientists in addressing the potential dangers to humanity arising from scientific discoveries. In 1963, he was presented with the Enrico Fermi Award by President Lyndon Johnson. In 1965, he was diagnosed with throat cancer. He died at home in 1967.Edward Teller – In 1951, Edward Teller, working with mathematician Stanislaw Ulam, developed the design for a hydrogen bomb. The force of detonation was no longer measured in kilotons, but in megatons. (One million tons of TNT.) Teller often proposed controversial technological solutions, such as excavating an Alaskan harbor using a thermonuclear device. But he was also one of the earliest scientists to warn of global climate change. He received numerous awards (Fermi Award, Einstein Award) and lived to the age of 95.Slide41
