Dissertation – Wikipedia
He was the son of Ismar Ehrlich and his wife Rosa Weigert, whose nephew was the great bacteriologist Karl Weigert. Ehrlich was educated at the Gymnasium at Breslau and subsequently at the Universities of Breslau, Strassburg, Freiburg-im-Breisgau and Leipzig. In he obtained his doctorate of medicine by means of a dissertation on the theory and practice of staining animal tissues. This work was one of the results of his great interest in the aniline dyes discovered by W.
Perkin in In he was appointed assistant to Professor Frerichs at the Berlin Medical Clinic, who gave him every facility to continue his work with these dyes and the staining of tissues with them. Ehrlich showed that all the dyes used could be classified as being basic, acid or neutral and his work on the staining of granules in blood cells laid the foundations of future work on haematology and the staining of tissues. In Ehrlich published his method of staining the tubercle bacillus that Koch had discovered and this method was the basis of the subsequent modifications introduced by Ziehl and Neelson, which are still used today.
From it was also derived the Gram method of staining bacteria so much used by modern bacteriologists. In Ehrlich became Titular Professor and in he qualified, as a result of his thesis Das Sauerstoffbedürfnis des Organismus The need of the organism for oxygen as a Privatdozent unpaid lecturer or instructor in the Faculty of Medicine in the University of Berlin. Later he became an Associate Professor there dissertation medizin Senior House Physician to the Charité Hospital in Berlin.
In Robert Koch, Director of the newly established Institute for Infectious Diseases, appointed Dissertation medizin as one of his assistants and Ehrlich then began dissertation medizin immunological studies with which his name will always be associated.
At the end of an Institute for the control of therapeutic sera was established at Steglitz in Berlin and Ehrlich was appointed its Director. Here he did further important work on immunology, dissertation medizin on haemolysins.
He also showed that the toxin-antitoxin reaction is, as chemical reactions are, accelerated by heat and retarded by cold and that the content of antitoxin in antitoxic sera varied so much for various reasons that it was necessary to establish a standard by which their antitoxin content could be exactly measured.
The methods of doing this dissertation medizin Ehrlich then established formed the basis of all future standardization of sera, dissertation medizin. This work and dissertation medizin other immunological studies led Ehrlich to formulate his famous side-chain theory of immunity.
In Ehrlich dissertation medizin appointed Public Health Officer at Frankfurt-am-Main and when, inthe Royal Institute of Experimental Therapy was established at Frankfurt, Ehrlich became its Director.
He now devoted himself to chemotherapy, basing his work on the idea, which had been implicit in his doctorate thesis written when he was a young man, that the chemical constitution of drugs used must be studied in relation to their mode of action and their affinity for the cells of the organisms against which they were directed.
His aim was, as he put it, to find chemical substances which have special affinities for pathogenic organisms, to which they would go, as antitoxins go to the toxins to which they are specifically related, and would be, as Ehrlich expressed it, «magic bullets» which would go straight to the organisms at which they were aimed.
To achieve this, Ehrlich tested, with the help of his assistants, hundreds of chemical substances selected from the even larger number of these that he had collected. He studied, among other subjects, the treatment of trypanosomiasis and other protozoal diseases and produced trypan red, which was, as his Japanese assistant Dissertation medizin showed, effective against trypanosomes. He also established, with A, dissertation medizin.
Bertheim, the correct structural formula of atoxyl, the efficiency of which dissertation medizin certain experimental trypanosomiases was dissertation medizin. This work opened a way of obtaining numerous new organic compounds with trivalent arsenic which Ehrlich tested.
At this time, the spirochaete that causes syphilis was discovered by Schaudinn and Hoffmann in Berlin, and Ehrlich decided to seek a drug that would be effective especially against this spirochaete. Among the arsenical drugs already tested for other purposes was one, the th of the series tested, which had been set aside in as being ineffective. Hata did so and found that it was very effective, dissertation medizin.
When hundreds of experiments had repeatedly proved its efficacy against syphilis, Ehrlich announced it under the name «Salvarsan». Subsequently, further work on this subject was done and eventually it turned out that the th arsenical substance to which the name «Neosalvarsan» was given, was, although its curative effect was less, more easily manufactured and, being more soluble, became more easily administered.
Ehrlich had, like so many other discoverers before him, to battle with much opposition before Salvarsan or Neosalvarsan were accepted for the treatment of human syphilis; but ultimately the practical experience prevailed and Ehrlich became famous as one of the main founders of chemotherapy. During the later years of his life, Ehrlich was concerned with experimental work on tumours and on his view that sarcoma may develop from carcinoma, also on his theory of athreptic immunity to cancer.
The indefatigable industry shown by Ehrlich throughout his life, his kindness and modesty, his lifelong habit of eating little and smoking incessantly 25 strong cigars a day, a box of which he frequently carried under one arm, his invariable insistence on the repeated proof by many experiments of the results he published, and the veneration and devotion shown to him by dissertation medizin his assistants have been vividly described by his former secretary, Martha Marquardt, whose biography of him has given us a detailed picture of his life in Frankfurt.
In Frankfurt the street in which his Institute was situated was named Paul Ehrlichstrasse after him, dissertation medizin, but later, when the Jewish persecution began, dissertation medizin, this name was removed because Ehrlich was a Jew. After the Second World War, however, when his birth-place, Strehlen, came under the dissertation medizin of the Polish authorities, they renamed it Ehrlichstadt, in honour dissertation medizin its great son.
Ehrlich was an ordinary, foreign, corresponding or honorary member of no less than 81 academies and other learned bodies in Austria, Belgium, Brazil, Denmark, Egypt, Finland, France, Germany, Great Britain, Greece, dissertation medizin, Hungary, ltaly, The Netherlands, Norway, Roumania, Russia, Serbia, Sweden, Turkey, the U.
and Venezuela. He held honorary doctorates of the Universities of Chicago, Göttingen, Oxford, Athens and Breslau, and was also honoured by Orders in Germany, Russia, Japan, Spain, Roumania, Serbia, Venezuela, Denmark Commander Cross of the Danebrog Dissertation medizindissertation medizin, and Norway Commander Dissertation medizin of the Royal St. Olaf Order. In he shared with Metchnikoff the highest scientific distinction, the Nobel Prize, dissertation medizin.
The Prussian Government elected him Privy Medical Counsel inpromoted him to a higher rank of this Counsel in and, inraised him to the highest rank, dissertation medizin, Real Privy Counsel with the title of Excellency.
Ehrlich married, in dissertation medizin, Hedwig Pinkus, who was then aged They had two daughters, Stephanie Mrs. Ernst Schwerin and Marianne Mrs. Edmund Landau. When the First World War broke out in he was much distressed by it and at Christmas of that year he had a slight stroke. He recovered quickly from this, but his health which had never, dissertation medizin, apart from a tuberculous infection in early life which had made it necessary for him to spend two years in Egypt, failed him, now began to decline and when, dissertation medizin, indissertation medizin, he went to Bad Homburg for a holiday, he had, on August 20 of that year, dissertation medizin second stroke which ended his life.
It was later edited and republished in Nobel Lectures, dissertation medizin. To dissertation medizin this document, always state the source as shown above.
