Otto Hahn was awarded the Nobel Prize in chemistry in 1944 for his discovery of nuclear fission. Although his coworkers Fritz Strassmann and Lise Meitner are also credited for the discovery, Hahn took most of the credit. Hahn took much interest in science and worked non stop day and night trying to figure things out. On top of discovering nuclear fission, he is also credited with discovering certain radioactive isotopes and elements. The main reason for Hahn’s success was not his actual academic studies but instead his love for chemistry.
Otto was born on March 8, 1879 in Frankfurt-am-Main. Growing up Hahn was the youngest of four boys, in a middle class family. Hahn was the only one of the boys to earn a college education. His father was his main influence as a child. He wanted his son to pursue the career of being an architect. During high school Otto Hahn read about chemistry on his own and began to take a deep interest in it. This side of him is what told him to follow this career into college.
During this time period in Germany it was common for college students to...
Johannes Brahms was born on Tuesday 7th may 1833, in the city of Hamburg the birthplace also of Mendelssohn. Johann Brahms was himself a musician, and played the double bass for a time at the Karl Schultze Theatre, and later in the Stadttheater orchestra. In 1847 Johannes attended a good Burgerschule (citizens? school), and in 1848 a better, that of one Hoffmann. When he was eight years old his father requested the teachers to be very easy with him because of the time that he must take for his musical studies.
As chief chemist in the nuclear power division he analyzed material used in reactor plant construction, nuclear propulsion plant systems, and worked on radiochemistry on nuclear submarines.
Otto Frank, born on May twelfth, 1889 in Frankfurt am Main in Germany belonged to a Jewish liberal family with three siblings(www.biography.com). He studied art history and economics at the University of Heidelberg, eventually leading him to working at a bank and then to accepting an internship position at Macy's Department Store in Manhattan. His father's death held him back from gaining the business experience he longed to discover at first, but determined the young Otto Frank continued his business(www.biography.com). In 1911, Otto Frank left America for his home in Germany, and eventually during 1914, became conscripted into the German army on the Western Front and earned the title of lieutenant(www.annefrank.org). Once the war ended, Frank took over the family bank, married his first wif...
Freud was born in 1856 to a large Jewish family living in Freiburg, Moravia. His family was economically limited, but that didn’t stop him from pursuing an intellectual education. In 1873 Freud went to the University of Vienna to become a medical student. In 1881 he received his doctorate and began working at the central hospital of Vienna.
Otto von Bismarck was born on April 1st 1815, in Schonhausen, Northwest of Berlin in the district of Magdeburg. His father was an upper class, land owning Prussian more commonly known as a Junker. (World Book, 1999, p. 381) (German News, 1998, p.1)(Passant, 1966, p.45)(Godesky, 1997, p.1)(Compton's Encyclopedia, 1999, p.1) During his early education Otto von Bismarck studied law at the universities of Berlin and Gottingen.

Carl Gustav Jung was born in Kessewil, Switzerland. He lived between 1875 and 1961 and was the only son of his father, a protestant clergyman. His extended family had good educational background and although quite a number of them were clergymen, he plumped for higher education. Jung became a Swiss psychiatrist and psychotherapist who developed analytical psychology. Owing to his personal experience, he postulated the concepts of introversion and extraversion personality, collective unconscious and individuation resulting in the study of integration and wholeness.
Physicists from 1939 onward conducted much research to find answers to such questions as how many neutrons were emitted in each fission, which elements would not capture the neutrons but would moderate or reduce their velocity , and whether only the lighter and scarcer isotope of uranium (U-235) fissioned or the common isotope (U-238) could be used. They learned that each fission releases a few neutrons.
Moseley's research starts of the chapter with his discovery of the proton, and how an element with more protons has a bigger mass making it necessary for it to come after a element with a weaker charge. with a weaker charge. When describing Moseley’s research and why a proton is significant, Sam includes how “electrons are attracted to an atom’s nucleus because electrons and protons have opposite charges”(99). The background knowledge included helps clarify the significance of the the discovery and why it make sense for element to be arranged based on weight. Mosley's decision of joining the army is significant and include by Sam to show what was need to motivate scientist to discover new elements. The death of moseley s significant due to “the best tribute scientist could pay Moseley was to hunt down all the missing elements”(102). New elements being discovered would only live for seconds due to them being unstable and later decay into (a new discovery as a result of element hunting) “a new element [the most] dramatic change on a nuclear level”(105). During this passage Sam uses unbiased language in order to provide for the most credible information. Moving to the Manhattan Project Sam includes the fact that the method being used was highly dependent on calculations. The people doing the calculations were women mostly “scientist wives due to them being bored
Richard P. Feynman was born in 1918 in Brooklyn; in 1942 he received his Ph.D. from Princeton. Already displaying his brilliance, Feynman played an important role in the development of the atomic bomb through his work in the Manhattan Project. In 1945 he became a physics teacher at Cornell University, and in 1950 he became a professor at the California Institute of Technology. He, along with Sin-Itero and Julian Schwinger, received the Nobel Prize in Physics in 1965 for his work in the field of quantum electrodynamics.
Jung was born July 26, 1875 to a well-educated family in Kesswil, Switzerland. He was raised with a love for language and literature, beginning Latin lessons at the age of 6.
Sigmund, son of Amalia and Jacob Freud, was born on May 6, 1856 in Freiburg, a rural town which was then a part of the Austro-Hungarian Empire. A confused child, he experienced extreme love, desire, and hate which ultimately inspired him to study human development. School consumed virtually all of Freud's time until he graduated from the University of Vienna in 1881, with a degree in medicine (Stevenson).
History has forgotten the landlady, but George de Hevesy went on to win the Nobel Prize in 1943 and the Atoms for Peace award in 1959. His was the first use of radioactive tracers - now routine in environmental science” (World Nuclea...
Freud was born in May 6, 1856 in the Czech Republic. He attended Spurling Gymnasium. At Spurling, he was first in his class and graduated Summa Cum Laude. After studying medicine at the University of Vienna, he gained respect while working as a physician. Freud and a friend were introduced to a case study that resulted in no cause, but they found that having the patient talk about her experiences had a calming effect on the symptoms. That was considered to be the beginning of the study of psychology.
Scientists from earlier times helped influence the discoveries that lead to the development of atomic energy. In the late 1800’s, Dalton created the Atomic Theory which explains atoms, elements and compounds (Henderson 1). This was important to the study of and understanding of atoms to future scientists. The Atomic Theory was a list of scientific laws regarding atoms and their potential abilities. Roentagen, used Dalton’s findings and discovered x-rays which could pass through solid objects (Henderson 1). Although he did not discover radiation from the x-rays, he did help lay the foundations for electromagnetic waves. Shortly after Roentagen’s findings, J.J. Thompson discovered the electron which was responsible for defining the atom’s characteristics (Henderson 2). The electron helped scientists uncover why an atom responds to reactions the way it does and how it received its “personality”. Dalton’s, Roentagen’s and Thompson’s findings helped guide other scientists to discovering the uses of atomic energy and reactions. Such applications were discovered in the early 1900’s by using Einstein’s equation, which stated that if a chain reaction occurred, cheap, reliable energy could b...
