Paul Ehrlich had a major influence on the pharmaceutical industry in the 19th century, enabling the world to find a cure for disease and developing a chemical theory about the body human. According to Ehrlich (1908), the concept of the cell is the axis around which all modern science of life revolves. The medical industry generation is leading the adoption of Ehrlich's discoveries to treat patients. Say no to plagiarism.

His father, Ismar Ehrlich, was a respected Jewish distiller, innkeeper and lottery collector. His mother, Rosa Ehrlich Weigert, was a hardworking woman with remarkable intelligence. Paul Ehrlich was the only son and youngest child in a family of six. The family lived in a comfortable house in the rural Silesian town. Rosa Weigert, Paul's mother, had a cousin Carl Weigert. Carl Weigert was a pathologist and director of Frankfurt Hospitals where he published hundreds of articles. Carl was only nine years older than Paul and the two became lifelong friends. It was Carl who guided him towards the world of medicine and tinctures. Paul attended the local primary school when he was just six years old. He then moved to Breslau and lived with a professor's family while studying at the humanist St Maria Magdalena gymnasium at the age of ten. There, he didn't like exams but his favorite subjects were mathematics and Latin. He then applied to the disappointing introductory natural sciences course at the University of Berslau, Strasbourg, which led to his acceptance to Strasbourg to study medicine. Building on his interest in tissue staining, Paul spent additional hours with anatomist Wilhelm Von Waldeyer performing histological practices with stains. However, he was not an exceptional student but he 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 with Paul and worked together to introduce him. with aniline dyes. In Weigert's laboratory, Paul studied the action of dyes on cells and tissues. His first paper in 1877 led him to take his state medical exam. After graduating, Paul was appointed chief physician at the Charité Hospital in Berlin. There, the hospital owner encouraged him to work on his histological research to improve the quality of patient diagnosis. At this time, his observation that the pH of dyes was linked to specific cellular components led him to believe that chemical affinity governs all chemical processes. In the 1880s, there was interest in Italy in questioning the cause of tuberculosis, as it was informally known as consuming the lungs and with the idea of ​​its contagious nature. Robert Koch conducted experiments in his laboratory in Berlin. In his experiments, he noticed the appearance of a rod-like microorganism in tuberculosis tissues, known as the tubercle bacillus. Paul highlighted Koch's study by showing 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.
