Salvador Luria
Salvador Luria was one of the founders of microbiology, as we know it. He emigrated from here from his native country of Italy in 1940. His work in the United States is his best known. His work on bacteriophage (bacterial virus) here brought up many new topics in bacteriology, biochemistry, and virology.
Born in 1912 in Turin, Italy Salvador Luria was born to David Luria and Ester Sacerdote. His father was a well-respected Jewish leader in his hometown. Salvador attended Liceo d’Azeglio high school. This was one of Northern Italy’s most highly recognized schools. After he finished high school he enrolled in medical school at the University of Turin. In medical school he studied with nerve tissue expert Giuseppe Levi. He met Ugo Fano who later taught him calculus and physics in an after school class using astronomy as a base.
The influence that Fano had on Salvador was so great that he decided to pursue basic sciences. He decided to go with Radiology, he believed this was the gap between physics and medicine. He received his medical degree in 1935. Although he had received his degree he was not happy. He believed Radiology was the most boring part of the medical world.
Salvador was drafted into the Italian Army as a medic. This proved he was not made for a medical career. He was discharged in 1937 and moved to Rome. In Rome he study at the Physics Institute of the University of Rome. He was shown the writings of Max Delbruck, who had boldly stated a gene, was a molecule. Salvador later said that Max’s writings were the “Holy Grail of biophysics.”
While living in an old broken down trolley car in the streets of Rome Salvador started a conversation with a microbiologist by the name of Geo Rita. Geo introduced him to bacteriophage, Salvador believed he could prove Max’s theory. He fled Europe in 1940 when the Nazi war machine was an approaching. He acquired an American visa and came to the United States.
Once he arrived in the United States he got a position at Columbia University. He got a hold of Delbruck and Delbruck agreed to help him in his experiments. They spent the summer of ’41 in Columbia University’s Biological Laboratory. Here Salvador rejoined his old friend Ugo Fano. In 1942-1943 he continued his bacteriophage studies. He was trying to prove the process or processes that caused bacteria mutation.
The nineteenth century introduced several great leaders into this world, many recognized by historians today. These men, Thomas Jefferson, Abraham Lincoln, and others, have all been honored and commemorated for their contributions. One such leader, José Martí, continues to remain anonymous outside the Hispanic community, and hidden in the shadows cast by these men. His name does not appear in the history books or on the tongues of many proud Americans, for he was neither a citizen of America nor an American hero.
Carlos Deluna was born on March 15th 1962. Carlos DeLuna, who was arrested for murder, was developmentally disabled and had a low IQ. He dropped out of junior high and took a series of manual jobs. He had a history of petty nonviolent crime, including robbery and car theft. DeLuna also developed a taste for huffing spray paint. He was arrested multiple times holding a can of spray paint with his hands and mouth “smeared with the stuff.” DeLuna was convicted of murder and sentenced to death by the state of Texas. On the night of February 4th,1983 a 24 year old gas station attendant named Wanda Lopez was murdered.Reporters said the young woman had been stabbed multiple time with a buckle knife. At his 1983 trial, Carlos DeLuna told the jury that on the day of the murder he had ran into Hernandez, who he'd known for the previous five years. The two men, who both lived in the southern Texas town of Corpus Christi, stopped off at a bar. Hernandez went over to a gas station, the Shamrock, to buy something, and when he didn't return DeLuna went over to see what was going on.Mrs.Lopez was killed while on the phone with the police, having just called 911 reporting a suspicious person. Police found DeLuna hiding in a truck a few blocks away. DeLuna told the jury that he saw Hernandez inside the Shamrock wrestling with a woman behind the counter. DeLuna said he was afraid and started to run. He had his own police record for sexual assault. "I just kept running because I was scared, you know." When he heard the sirens of police cars screeching towards the gas station he panicked and hid under a pickup truck where, 40 minutes after the killing, he was arrested.(Pilkington) DeLuna always maintained that he didn't do it, but waited until his tr...
In the novel, Pedro Páramo, by Juan Rulfo, settings serve the purpose of being much more than merely locations. Various settings are utilized to represent symbols throughout the novel in order for Rulfo to develop the plot of the novel. Comala is a location that clearly acts as a symbol in Rulfo’s writing; however, to truly recognize the symbolism in the novel and to acknowledge the presence of key themes such as those of purgatory, religion, and oppression, it is necessary to analyze less conspicuous settings, particularly, the home of doña Eduviges, the church, and the Media Luna.
...en he was. Even if he wasn't out seeking new advances in science, he sought to improve the human condition.
There he inspired many students and tutored them to become professionals in the medical field. Many of these students included Fabricius ab Aquapendente (gave the first clear description of the semi lunar valves of the veins, which later provided many people with a crucial point in his famous argument for circulation of the blood) and Volcher Coiter (described human embryology as well as the comparative osteology of animals and illustrated his own work.... ... middle of paper ...
For long before the 1918 pandemic, doctors had been trying to isolate the microorganism that causes influenza. In 1892, one man, Dr. Friedrich Johann Pfeiffer, believed he had the answer. His discovery, Pfeiffer’s bacillus or Hemophilus influenzae, was widely known as the culprit. However, during the first wave of the 1918 pandemic, doctors lost faith in Pfeiffer’s bacillus. They searched for it in patients, but rarely found it. In the second wave, the bacterium was present in many, but by no means all, cases of Spanish flu. If it was the cause of influenza, it should have been present in all cases (Kolata, Flu 64-65).
Louis Agassiz (1807-1873), born in Switzerland, was a naturalist. (Gould, 74) In 1840’s, Agassiz migrated to America and became a professor at Harvard. (Gould, 75) Agassiz was an extremely successful man in the science world. (Gould, 75) As a matter of fact, he raised money to support his buildings, collections, and publications. (Gould, 75)

A master and maker in many fields, Linus Pauling lived a very long and productive life spanning nearly the entire twentieth century. By the time he was in his twenties, he had made a name for himself as a scientist. After many significant contributions including his work on the nature of the chemical bond, he turned to chemical biology and is generally accepted as the founder of molecular biology. Later in his life he became very involved in issues of politics and peace for which he is somewhat less well known. In his later years, he became interested in health and medicine and specifically in the use of vitamin C to prevent ailments from the common cold to cancer.
He said “Milk maids who caught cowpox did not later than catch smallpox protected against inoculated smallpox. He also said “Smallpox vaccines were the first to be a successful vaccine to be developed.” So he made vaccines that first started with cowpox that lead into something really dangerous that we have found vaccines for today.
Another man that made discoveries that reinforced those of Pasteur was Robert Koch. Robert Koch isolated the germ that causes tuberculosis, identified the germ responsible for Asiatic cholera, and developed sanitary measures to prevent disease. (1) In the late 1880s, genes, white blood cells, and aspirin were discovered. An Augustinian monk from Austria, Johann Gregor Mendel, experimented in the crossplanting of pea plants.
Albert Einstein was born in Ulm, Germany on March 14th, 1879 to Hermann Einstein and Pauline Einstein. For most of his live he lived in Ulm, a small town outside of Munch, Germany. At the age of 1 the Einstein family moved to Zurich, Germany. The Einstein family moved to Zurich so that Hermann, Albert’s father could work with his brother Jakob in his Manufacturing business. Albert’s family consisted of his mother and father, himself, and his younger sister Maja. Albert Einstein’s parents worried about him because he rarely spoke as a child, thus causing them to think that he had a brain development issue.
Giovanni Battista Lulli was born on November 28, 1632. His father, Lorenzo di Maldo, was a miller and his mother, Caterina del Sera, was a miller’s daughter. Lully was born in Florence, Italy and lived there until age 11. While in Italy he studied dance and music; he played violin and guitar. In March of 1646 he moved to France to tutor Mlle de Montpensier in Italian. There he studied composition and harpsichord. Lully was able to hear the King’s grande bande perform, witness balls where the best French dance music was played.
He had wanted to be a research scientist but anti-Semitism forced him to choose a medical career instead and he worked in Vienna as a doctor, specialising in neurological disorders (disorders of the nervous system). He constantly revised and modified his theories right up until his death but much of his psychoanalytic theory was produced between 1900 and 1930.
