Paul Ehrlich


I. A World To Change

Everyone on this earth has to be grateful to Paul Ehrlich because he made so many advances
in medical research. Our life expectancy rate would still be around forty years if Ehrlich
hadn't been interested in chemistry and biology as a young boy. If Ehrlich hadn't combined
so many different chemicals, he would have never combined the chemical known as number
606.

Ehrlich helped Emil von Behring find an antitoxin for diphtheria. Diphtheria is a disease
that particularly affects children and sometimes leads to death. In 1894, mothers no
longer had to worry about their child dying of diphtheria because of Ehrlich's help in the
discovery of the antitoxin for the deadly disease.

Another discovery Ehrlich made was of a dye called trypan red. Trypan red helped destroy
cells that caused sleeping sickness. His research of antibodies and understanding how the
antibodies attack harmful substances that enter the body has made him the "founder" of
modern chemotherapy.

Ehrlich is best known for his work on curing syphilis. Syphilis is an infectious disease
transmitted by sexual contact or kissing. Ehrlich named the compound that cured syphilis
"salvarsan". This was a very effective way to cure syphilis.

II. Background

A. Family

Paul Ehrlich was born on March 14, 1854 in Strehlen, Silesia. Ehrlich was born in to a
middle-class, Jewish family. He was the only son and fourth child of Ismar and Rosa
Ehrlich. His father owned a small distillery. Ehrlich had an Orthodox Jewish upbringing in
a time when being a Jew was controversial.

B. Childhood
When Ehrlich was six years old he started his schooling at the local primary school. At
age ten, he boarded with a professor's family in Breslau and went to St. Maria Magdalena
Humanistic Gymnasium. Ehrlich was often at the top of his class and his best subjects were
math and Latin.

C. Advanced Education and Training
Ehrlich took an introductory course in natural sciences at Breslau University in 1872. He
then went to Strasbourg for three semesters. In 1874, Ehrlich returned to Breslau where he
completed his medical degree studies. In 1877, he passed the state medical examination. In
1878 he received his medical degree.

III. Research and Development
A. Discussion of the Area of Biology
Most of Ehrlich's discoveries had something to do with the immune system. The immune
system is a body system that is responsible for destroying disease-causing cells. When
Ehrlich was still in school, he was staining white blood cells to see their different
characteristics with his work on antibodies, he is knows as the "founder" of modern
chemotherapy. If Ehrlich had not learned about the immune system, then he might not have
discovered the different things he discovered.

B. Discoveries or Work
1. Summary (of all discoveries or work)
Ehrlich helped to discover the antitoxin for diphtheria. Ehrlich discovered Trypan red, a
dye that helped destroy cells that cause sleeping sickness. In 1909, Ehrlich discovered
salvarsan, a cure for syphilis. His work with trypan red and salvarsan marked the
beginning of modern chemotherapy.

2. Details of Major Work or Major Discovery
In 1907, Ehrlich was working on a chemical compound. This compound he was testing on
trypanosomes, which are the cells that cause sleeping sickness. The compound was named
606. Since it did not work, Ehrlich went on.

  • ALCATRAZ ISLAND AND PRISON
    ALCATRAZ ISLAND AND PRISON Alcatraz Island has quite a distinct history. Many people know that Alcatraz served as a federal prison, but most are reluctant to know that this island served as fort. Built before the Civil War, it served two main purposes. First, that it was to guard the San Francisco bay area from enemy ships against a foreign invasion, and second, to hold hostage prisoners of war or POW\'s as they were called. In this report, I\'ll show you how this fortress came to be a federal p

    Gangsterism in the 1920s “The Roaring Twenties,”; what a perfect aphorism. It was certainly roaring with music and dance, but it also was roaring with gangsters. In the aspect of gangsterism, the thirties were also roaring. Americans in this time period tolerated criminals, especially those involved in bootlegging. Bootlegging is the smuggling of illegal substances. Bootlegging could have possibly been tolerated because of the recent outlaw of alcohol during this time period, known as the Prohib

  • International Adoption
    International Adoption International Adoption There are many reasons as to why people choose to adopt a child. Sometimes it has to do with infertility and couples decide to adopt children because, “I could not have biological children and I do not believe in some methods of fertility treatments (Carney),” but there are other reasons too. According to Christine Adamec, some people think that it is better to adopt than to bring another child into the world. Others do not want to pass a certain gen
  • Sex Ed
    Sex Ed There are many reasons why people argue for and against sex education being a set curriculum in our school systems, but not many people look at the facts of the issue before deciding that sex education is not right. The plain truth is that there has been a dramatic increase in the number of teenagers that have become sexually active. The age at which sexual intercourse first occurs is becoming younger. According to Stong and Devault, in 1996 17% of girls and 38% of boys admitted to having

The Utopian society strives for a perfect state of well-being for all persons in the community, and over-emphasizes this factor, where no person is exposed to the reality of the world. As each novel progresses we see that neither society possesses family values nor attempts to practice them. Neither are pa
