Paul Ehrlich had a great influence on the pharmaceutical industry in the 19th century, enabling the world to find a cure for a disease and developing a chemical theory about the human body. According to Ehrlich (1908) the concept of the cell is the axis around which all modern life science revolves. The medical industry generation is driving the adoption of Ehrlich's discoveries to treat patients. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an original essay Paul Ehrlich was born on March 14, 1854 in Strehlen, Silesia, now known as Strzelin, Poland. His father, Ismar Ehrlich, was a respected Jewish distiller, innkeeper and lottery collector. His mother, Rosa Ehrlich Weigert, was an industrious woman of considerable intelligence. Paul Ehrlich was the only son and last born in his family of six. The family lived in a comfortable house in the Silesian country town. Rosa Weigert, Paul's mother, had a cousin Carl Weigert. Carl Weigert was a pathologist and hospital prosecutor in Frankfurt where he published hundreds of articles. Carl was only nine years older than Paul and they both became lifelong friends. It was Carl who guided him into the world of medicine and tinctures. Paul attended the local primary school when he was just six years old. He then moved to Wroclaw and lived with a professor's family while studying at the St. Mary Magdalene Humanistic Gymnasium at the age of ten. There he didn't like exams but his favorite subjects were mathematics and Latin. He subsequently enrolled in the disappointing introductory course in natural sciences at the Berslau University of Strasbourg, which led to his acceptance to Strasbourg to study medicine. With his interest in tissue staining, Paul put in extra hours with anatomist Wilhelm Von Waldeyer to perform histological practices with dyes. However, he was not an exceptional student, but still managed to pass his exams. In 1874 he returned to Berslau to obtain a medical degree. The pathologists Julius Cohnheim and Carl Weigert, the physiologist Rudolf Heidenhain, the botanist Ferdinand Cohn, the American pathologist WH Welchand, and the Danish bacteriologist J Salomonsen were all friends of Paul and worked together to introduce him. to aniline dyes. In Weigert's laboratory, Paul studied the action of dyes on cells and tissues. His first paper in 1877 led him to pass the state medical exam. After graduation, Paul was appointed head physician at the Charite hospital in Berlin. There the hospital owner encouraged him to work on his histological research to improve the quality of patient diagnosis. During that time, his observation that the pH of dyes correlated with specific cellular components led him to believe that chemical affinity governed all chemical processes. In the 1880s in Italy it was interesting to wonder about the cause of tuberculosis because it was informally known as lung wasting along with the idea of ​​its contagious nature. Robert Koch conducted experiments in his laboratory in Berlin. In his experiments, he noted the presence of a rod-like microorganism in tuberculosis tissues known as the tuberculosis bacillus. Paul emphasized Koch's study by demonstrating that the bacteria failed to stain in his alkaline aqueous dye solution because the dye had penetrated the bacillary cell wall which was acidic. In 1888, Paul had to take a break from his career because he was affected by bacteria during his laboratory work. In 1885, he challenged Pfluger's conclusion that oxidation and reduction in cells are direct entry and exit.
