SEMMELWEIS, IGNAZ PHILIPP
(b. Buda, Hungary, 1 July 1818: d. Vienna, Austria, 13 August 1865)
Semmelweis was one of the most prominent medical figures of his time. His discovery concerning the etiology and prevention of puerperal fever was a brilliant example of fact-finding, meaningful statistical analysis, and keen inductive reasoning. The highly successful prophylactic hand washings made him a pioneer in antisepsis during the prebacteriological era in spite of deliberate opposition and uninformed resistance.
Semmelweis was born in Tabán, an old commercial sector of Buda. The fifth child of a prosperous shopkeeper of German origin, he received his elementary education at the Catholic Gymnasium of Buda, then completed his schooling at the University of Pest between 1835 and 1837.
In the fall of 1837, Semmelweis traveled to Vienna, ostensibly to enroll in its law school. His father wanted him to become a military advocate in the service of the Austrian bureaucracy. Soon after his arrival, however, he was attracted to medicine; and seemingly without parental opposition he matriculated in the medical school.
After completing his first year of studies at Vienna, Semmelweis returned to Pest and continued at the local university during the academic years 1839–1841. The backward conditions in the school, however, caused his return to Vienna in 1841 for further studies at the Second Vienna Medical School, which became one of the leading world centers for almost a century with its amalgamation of laboratory and bedside medicine. During the last two years of study, Semmelweis came in close contact with three of the most promising figures of the new school: Karl von Rokitansky, Josef Skoda, and Ferdinand von Hebra.
After voluntarily attending seminars led by these teachers, semmelweis completed his botanically oriented dissertation early in 1844. He remained in Vienna after graduation, repeating a two-month course in practical midwifery and receiving a master’s degree in the subject. He also completed some surgical training and spent almost fifteen months (October 1844–February 1846) with Skoda learning diagnostic and statistical methods. Finally Semmelweis applied for the position of assistant in the First Obstetrical Clinic of the university’s teaching institution, the Vienna General Hospital.
In July of 1846 Semmelweis became the titular house officer of the First Clinic, which was then under the direction of Johann Klein. Among his numerous duties were the instruction of medical students, assistance at surgical procedures, and the regular performance of all clinical examinations. One of the most pressing problems facing him was the high maternal and neonatal mortality due to puerperal fever, 13.10 percent. Curiously, however, the Second Obstetrical Clinic in the same hospital exhibited a much lower mortality rate, 2.03 percent. The only difference between them lay in their function. The First was the teaching service for medical students, while the Second had been selected in 1839 for the instruction of midwives. Although everyone was baffled by the contrasting mortality figures, no clear explanation for the differences was forthcoming. The disease was considered to be an inevitable aspect of contemporary hospital-based obstetrics, a product of unknown agents operating in conjunction with elusive atmospheric conditions.
After a temporary demotion to allow the reinstatement of his predecessor, who soon left Vienna for a professorship at Tübingen, Semmelweis resumed his post in March 1847. During his short vacation in Venice, the tragic death of his friend Jakob Kolletschka, professor of forensic medicine, occurred after his finger was accidentally punctured with a knife during a postmortem examination. Interestingly, Kolletschka’s own autopsy revealed a pathological situation akin to that of the women who were dying from puerperal fever.
Prepared through his intensive pathological training with Rokitansky, who had placed all cadavers from the gynecology ward at his disposal for dissection, Semmelweis made a crucial association. He promptly connected the idea of cadaveric contamination with puerperal fever, and made a detailed study of the mortality statistics of both obstetrical clinics. He concluded that he and the students carried the infecting particles on their hands from the autopsy room to the patients they examined during labor. This startling hypothesis led Semmelweis to devise a novel system of prophylaxis in May 1847. Realizing that the cadaveric smell emanating from the hands of the dissectors reflected the presence of the incriminated poisonous matter, he instituted the use of a solution of chlorinated lime for washing hands between autopsy work and examination of patients. Despite early protests, especially from the medical students and hospital staff, Semmelweis was able to enforce the new procedure vigorously; and in barely one month the mortality from puerperal fever declined in his clinic from 12.24 percent to 2.38 percent. A subsequent temporary resurgence of the dreaded ailment was traced to contamination with putrid material from a patient suffering from uterine cancer and another with a knee infection.
In spite of the dramatic practical results of his washings, Semmelweis refused to communicate his method officially to the learned circles of Vienna, nor was he eager to explain it on paper. Hence, Hebra finally wrote two articles in his behalf, explaining the etiology of puerperal fever and strongly recommending use of chlorinated lime as a preventive. Although foreign physicians and the leading members of the Viennese school were impressed by Semmelweis’ apparent discovery, the papers failed to generate widespread support.
During 1848 Semmelweis gradually widened his prophylaxis to include all instruments coming in contact with patients in labor. His statistically documented success in virtually eliminating puerperal fever from the hospital ward led to efforts by Skoda to create an official commission to investigate the results. The proposal was ultimately rejected by the Ministry of Education, however, a casualty of the political struggle between the defeated liberals of the 1848 movement and the newly empowered conservatives in both the university and the government bureaucracy.
Angered by favorable reports concerning the new methods that indirectly represented an indictment of his own beliefs and actions, Klein refused to reappoint Semmelweis in March 1849. Undaunted, he applied for an unpaid instructorship in midwifery. In the meantime he began to carry out animal experiments to prove his clinical conclusions with the aid of the physiologist Ernst Brücke and a grant from the Vienna Academy of Sciences.
Semmelweis was at last persuaded to present his findings personally to the local medical community. On 15 May 1850 he delivered a lecture to the Association of Physicians in Vienna, meeting under the presidency of Rokitansky. The following October he received the long-awaited appointment as a Privatdozent in midwifery, but the routine governmental decree stipulated that he could only teach obstetrics on a mannequin. Faced with financial difficulties in supporting his family, and perhaps discouraged, Semmelweis abruptly left the Austrian capital, returning to Pest without notifying even his closest friends. Such a hasty decision jeopardized forever his chances to overcome the Viennese skeptics gradually with the dedicated help of Rokitansky, Skoda, Hebra, and other colleagues.
In Hungary, Semmelweis found a backward and depressed political and scientific atmosphere following the crushing defeat of the liberals in the revolution of 1848. Despite the unfavorable circumstances, he managed to receive an honorary appointment and took charge of the maternity ward of Pest’s St. Rochus Hospital in May 1851, remaining there until 1857. He soon was able to implement his new prophylaxis against puerperal fever, with great success, while building an extensive private practice.
Following the death of the incumbent, Semmelweis was appointed by the Austrian Ministry of Education to the chair of theoretical and practical midwifery at the University of Pest in July 1855, although he had been only the second choice of the local medical faculty. He subsequently devoted his efforts to improving the appalling conditions of the university’s lying-in hospital, a difficult task in the face of severe economic restrictions. In 1855 Semmelweis instituted his chlorine hand washings in the clinic, and he gradually achieved good results despite initial carelessness by the hospital staff. His lectures, delivered in Hungarian by decree of the Austrian authorities, attracted large student audiences. Semmelweis also became active in university affairs, serving on committees dealing with medical education, clinical services, and library organization.
In 1861 Semmelweis finally published his momentous discovery in book form. The work was written in German and discussed, at length, the historical circumstances surrounding his discovery of the cause and prevention of puerperal fever. A number of unfavorable foreign reviews of the book prompted Semmelweis to lash out against his critics in a series of open letters written in 1861–1862, which did little to advance his ideas.
After 1863 Semmelweis’ increasing bitterness and frustration at the lack of acceptance of his method finally broke his hitherto indomitable spirit. He became alternately apathetic and pathologically enraged about his mission as a savior of mothers. In July 1865 Semmelweis suffered what appeared to be a form of mental illness; and after a journey to Vienna imposed by friends and relatives, he was committed to an asylum, the Niederösterreichische Heil- und pflegeanstalt. He died there only two weeks later, the victim of a generalized sepsis ironically similar to that of puerperal fever, which had ensued from a surgically infected finger.
Semmelweis’ achievement must be considered against the medical milieu of his time. The ontological concept of disease insisted ion specific disease entities that could be distinctly correlated both clinically and pathologically. Puerperal fever, however, exhibited multiple and varying anatomical localizations and a baffling symptomatology closely related to the evolution of generalized sepsis. The apparent connection between this fever and erysipelas further clouded the issue. Moreover, the idea of a specific contagion causing the disease was not borne out by the clinical experience.
In the face of such theoretical uncertainties and the profusion of causes attributable to the disease, Semmelweis displayed a brilliant methodology borrowed from his teachers at the Second Vienna Medical School. He partially solved the puzzle through extensive and meticulous dissections of those who had succumbed to the disease, eventually recognizing the crucial similarities of all septic states. The methodical exclusion of possible etiological factors–one variable at a time–followed Skoda’s diagnostic procedure, while the employment of statistical data was transferred from therapeutic analysis to the elucidation of the decisive factor responsible for the disease. In finally arriving at his discovery, Semmelweis successfully seized upon his built-in control group of women at the Second Clinic, a fortunate situation unparalleled elsewhere.
The subsequent lack of recognition for Semmelweis’ prophylaxis can be attributed to several factors. An initial lack of proper publicity among Viennese and foreign visiting physicians led to misunderstandings and an incomplete assessment of the intended procedure. Further, political feuds led to an identification of Semmelweis with the liberal and reform-oriented faction of the Viennese medical faculty, a group temporarily thwarted in their objectives by the crushing defeat of 1848. Finally, Semmelweis’ abrupt departure from the arena robbed him of the possibility of eventually persuading his Viennese colleagues of the soundness of the chlorine washings. Operating from a politically suppressed and scientifically backward country with a second-rate university, Semmelweis was effectively hampered in the promulgation of his ideas. His later, rather violent and passionate polemics added little further credence to a somewhat cumbersome method that was difficult to implement among hospital staff members content with the status quo. Most important, however, was the lack of a good explanation for Semmelweis’ empirically derived procedure, a development made possible only through the ensuing work of Pasteur.
I . Original Works. Semmelweis’ meager writings are listed in Medical Classics, 5 (1941), 340–341; and in Bulletin of the History of Medicine, 20 (1946), 653–707. His most important work was Die Aetiologie, der Begriff und die Prophylaxis des Kindbettfiebers (Pest-Vienna-Leipzig, 1861), reprinted with a new introduction by A.F. Guttmacher (New York-London), 1966). This work was translated into English by F. R. Murphy and appeared as “The Etiology, the Concept and Prophylaxis of Childbed Fever,” in Medical Classics, 5 (1941), 350–773. However, Semmelweis first published his ideas in 1858 under the title “A gyermekagyi láz koroktana” (“The Etiology of Childbed Fevers”) in Orvosi hétilap (1858); no. 1, 1–5; no. 2, 17–21; no.5, 65–69: no. 6, 81–84; no. 21, 321–326: no. 22, 337–342: no. 23, 353–359.
In 1903 the Hungarian Society for the publication of Medical Works collected and published semmelweis’ works in Hungarian while the Hungarian Academy simultaneously arranged for an edition of the collected writings in German; Semmelweis Gesammelte Werke, edited and partially translated from the Hungarian by T. von Györy (Jena, 1905). This book contains articles dealing with gynecological subjects originally published in Orvosi hetilap, A short letter written by Semmelweis in English and dated at Pest, 21 April 1862, is “On the Origin and prevention of Puerperal Fever,” in Medical Times and Gazette (London), 1 (1862), 601–602.

Semmelweis, Ignaz Philipp (1818-1865)
Semmelweis, Ignaz Philipp (1818-1865)
Along with American physician Oliver Wendell Holmes (1809–1894), Ignaz Semmelweis was one of the first two doctors worldwide to recognize the contagious nature of puerperal fever and promote steps to eliminate it, thereby dramatically reducing maternal deaths.
Semmelweis was born in Ofen, or Tabàn, then near Buda, now part of Budapest, Hungary, on July 1, 1818, the son of a Roman Catholic shopkeeper of German descent. After graduating from the Catholic Gymnasium of Buda in 1835 and the University of Pest in 1837, he went to the University of Vienna to study law, but immediately switched to medicine. He studied at Vienna until 1839, then again at Pest until 1841, then again at Vienna, earning his M.D. in 1844. Among his teachers were Karl von Rokitansky (1804–1878), Josef Skoda (1805–1881), and Ferdinand von Hebra (1816–1880). He did postgraduate work in Vienna hospitals in obstetrics, surgery, and, under Skoda, diagnostic methods. In 1846, he became assistant physician, tantamount to senior resident, at the obstetrical clinic of the Vienna General Hospital.
In the mid-nineteenth century, the maternal death rate for hospital births attended by physicians was much higher than for either home births or births attended by midwives. The principal killer was puerperal fever, or childbed fever, whose etiology was then unknown, but which Louis Pasteur (1822–1895) learned in 1879 was caused by a streptococcal infection of the open wound at the site of the placenta in women who had recently given birth. The infection could remain topical or it could pass through the uterus into the bloodstream and quickly become fatal. Before Semmelweis and Holmes, physicians generally assumed that puerperal fever was an unpreventable and natural consequence of some childbirths, and accepted the terrifying mortality statistics.
Witnessing so many healthy young mothers sicken and die greatly affected Semmelweis, and he grew determined to discover the cause and prevention of puerperal fever. Using Rokitanksy's pathological methods, he began a comparative study of autopsies of puerperal fever victims. The break-through came when his fellow physician, Jakob Kolletschka (1803–1847), died of blood poisoning after cutting his finger while performing an autopsy. Semmelweis noticed that the pathological features of the autopsy on Kolletschka's body matched those of the autopsies of the puerperal fever victims. Semmelweis then only suspected, and did not prove, that the fever was a septicemia, an intrusion of microorganisms from a local infection into the bloodstream, but he instantly took action. In May 1847, he ordered all personnel under his authority to wash their hands between patients. This was a novel, radical, and unpopular rule, but in just a month the maternal death rate at the Vienna General Hospital dropped from twelve to two percent.
Even though Semmelweis had solid results and statistics on his side, many physicians simply refused to believe that washing their hands, which they considered undignified, could save lives. Resistance to his rule stiffened. Semmelweis made many powerful enemies, and in March 1849, he was demoted from his supervisory role. He served at St. Rochus Hospital in Pest from 1851 to 1857, but never achieved his former professional status.
Holmes was facing a similar crisis in America. In 1843, Holmes first claimed in print that puerperal fever was contagious. Semmelweis first published his findings in 1848. Now having heard of Semmelweis, Holmes in 1855, expanded his original article into a small book that explicitly praised Semmelweis. Likewise, having now heard of Holmes, Semmelweis published Die Aetiologie, der Begriff, und die Prophylaxis des Kindbettfiebers [The Etiology, Concept, and Prophylaxis of Childbed Fever] in 1861. The book was not well received. Semmelweis was a poor prose stylist, and his lack of writing skill adversely affected his campaign. Holmes, on the other hand, an accomplished essayist and poet as well as a first-rate physician, proved more persuasive, although it would still be thirty years before sanitary and hygienic methods became standard in American and European hospitals.
While no one ridiculed Holmes, who had enough charm and grace to forestall such attacks, Semmelweis became subject of mockery in the central European medical community. In 1863, the frustration he had long felt finally took its toll on his spirit. He became chronically depressed, unpredictably angry, socially withdrawn, and increasingly bitter. In July 1865, a coalition of colleagues, friends, and relatives committed him to the Niederösterreichische Heil-und Pflegeanstalt, an insane asylum in Döbling, near Vienna. He died there a month later, on August 13, 1865, from bacteremia due to an infected cut on his finger, with symptoms markedly akin to those of puerperal fever.

Ignaz Philipp Semmelweis
Ignaz Philipp Semmelweis
The Hungarian physician Ignaz Philipp Semmelweis (1818-1865) was a pioneer of antisepsis in obstetrics and demonstrated that many cases of puerperal fever could be prevented.
Ignaz Philipp Semmelweis, the son of a prosperous shopkeeper, was born on July 1, 1818, at Buda, a city united with Pest in 1873 to form Budapest. After 2 years at the University of Pest, 19-year-old Ignaz matriculated at the University of Vienna as a law student. Unhappy, he returned to the University of Pest and studied medicine (1838-1840). After completing further studies at the University of Vienna, he received a medical degree in April 1844. Following 4 months of special instruction in midwifery, Semmelweis became a provisionary assistant at the First Obstetric Clinic in the large Vienna Lying-In Hospital. Two years later he became a regular assistant to the director of this clinic.
Semmelweis was especially distressed by the horrors of puerperal fever. Within a few hours after delivery, numerous mothers would be afflicted with high fever, rapid pulse, distended abdomen, and excruciating pain. One out of 10 would die as a result of this infection. One observation haunted Semmelweis. The hospital was divided into two clinics: the first for the instruction of medical students, the second for the training of midwives. The mortality due to puerperal fever was significantly greater in the first clinic. Traditional ideas ascribed puerperal fever to epidemic influences; if this were true, both clinics should be equally affected. Overcrowding was suggested; yet the second clinic was ordinarily more crowded than the first. Semmelweis incessantly searched for a better understanding of his puzzling observations.
In 1847 Semmelweis's colleague J. Kolletschka unexpectedly died of an overwhelming infection following a wound he sustained while performing an autopsy. Semmelweis realized that the course of the disease in his friend was remarkably similar to the sequence of events in puerperal fever. Here was an explanation of the difference in mortality between the two clinics: the medical students and teachers dissected corpses, whereas the midwives did no autopsies. The teachers and pupils could thus carry infectious particles from the cadavers to the natural wounds of a woman in childbirth. Accordingly, teachers and students who had been dissecting were requested to wash their hands with a solution of chlorinated lime before examining the laboring patients. As a result, during 1848 the mortality of the first clinic was less than that of the second clinic.
Surprisingly, opposition to Semmelweis's observations was intense, for the paradox of being healer and murderer was intolerable for most. When confronted with Semmelweis's explanations, conscientious obstetricians pleaded "not guilty." Semmelweis could not understand these reactions. A few outstanding doctors supported him; nevertheless, the tide of controversy grew to such an extent that Semmelweis was "retired" from his position as assistant at the first clinic. In 1850 he left Vienna and returned to Budapest.
At the St. Rochus Hospital in Budapest, Semmelweis was allowed to introduce disinfection in the obstetrical division. In 1855 he became professor of theoretical and practical midwifery at the University of Pest. In 1857 he married. But the deaths of two children during the next few years added personal grief to professional suffering, a suffering that intensified as opposition to his ideas spread throughout Europe.
With much reluctance Semmelweis organized his observations and published his great work on puerperal fever, The Etiology, Concept, and Prophylaxis of Childbed Fever (1861). Even this did not silence his opponents, and Semmelweis, unable to accept this resistance, was committed to an insane asylum in 1865, where he died of blood poisoning. Not until 1883 did the Boston Lying-In Hospital introduce methods of antisepsis, methods similar to those used several decades earlier by Semmelweis.

Semmelweis, Ignaz Philipp
Ignaz Philipp Semmelweis (Ĭg´näts fē´lĬp zĕm´əlvīs), 1818–65, Hungarian physician. He was a pioneer in employing asepsis. While on the staff of the general hospital in Vienna, he recognized the infectious nature of puerperal fever and insisted that attendants in obstetrical cases thoroughly cleanse their hands; he thus greatly reduced the mortality rate from infection in childbirth. Ridicule of his belief caused him to leave Vienna (1854) for Pest, Hungary, and ultimately drove him to insanity and suicide. He recorded his results in The Cause, Concept, and Prophylaxis of Childbed Fever (1861, tr. 1941), but the value of his work was not fully recognized until c.1890.
