Hans Joachim Schmidt

from Wikipedia, the free encyclopedia

Hans Joachim Schmidt (born January 5, 1907 in Riga , Latvia ; † March 19, 1981 in Vienna , Austria ) was a German dentist as well as press officer and public relations officer for the Baden-Württemberg State Dental Association , co-founder of the German Fluorine Commission in the German Committee for Youth Dental Care (DAJ) and the European Organization for Caries Research (ORCA). He was one of the most committed German advocates of the use of fluoride for caries prophylaxis , especially the fluoridation of drinking water.

life and work

His parents were the "Reichsdeutsche factory owner" Johannes Schmidt and his wife Claire, b. Tackle. In 1914 he left his Baltic homeland and passed the school-leaving examination in Wuppertal-Elberfeld in 1928 after changing schools several times. He then studied "Law and Political Science" in Königsberg , Munich , Marburg and Würzburg . He also began studying dentistry in Würzburg. Politically committed, he expressed himself in a contemporary style on the annexation of Memelland . In January 1936 he was awarded a degree in economics with his dissertation "The additional credit" to become a Dr. rer. pole. doctorate and in February 1937 at the Hygiene Institute under Maximilian Knorr as Dr. med. dent. with a dissertation on statistical studies of dental caries . In the attached curriculum vitae he mentions: "As head of the working group" DAF "of the Würzburg State Science Faculty, I took part in a four-week course at the training castle of the NSDAP, Berlin-Wannsee". As early as 1936, when cand. Med. dent. he had written articles for the Dental Bulletin and then turned more intensively to dental statistics. He attracted attention with his work Dental Statistics , which was published in 1938 by Hippokrates Verlag, Stuttgart. Then he realized that “in England and America, extraordinarily high government grants are granted for research purposes, which we did not know. A time that imperiously demands that Germany's reputation on the world market remains equally valid, admonishes all those who are somehow called to collaborate in science to be very active ”. Even during the Second World War he occasionally found time to communicate. A wound that tied him to bed for a long time gave him the opportunity to collect literature on “vital substances” and the etiology of caries, with the help of editors of several magazines. From 1948 "some American gentlemen" joined the assistants of the Stuttgart dentist (John William Knutson, Henry Trendley Dean , Basil Glover Bibby, Francis Arthur Arnold). In 1952, Hans Joachim Tholuck referred to Schmidt as one of the “pioneers of the idea of ​​fluoridation” in Germany, alongside Walter Drum and Rudolf Schill. This is impressively proven by Schmidt's monographs (from 1951) and numerous journal articles (on fluoride from 1949).

An author with difficulty expressing himself

Wherever an editorial team did not intervene in a helpful way, an attentive reader cannot miss some stylistic peculiarities in Schmidt's remarks: misspelled terms and author names, new words, telegram style and stereotypical statements. The Giessen dentist and physiologist Albert Keil made the following comments, for example, in a review of Schmidt's “Caries prophylaxis through fluorotherapy?” (1951): “Some sentence formulations are difficult to understand or inappropriate, as the manuscript would have had to be checked again in linguistic terms ( made impossible , Contact contact , In Germany, the rows of teeth in Berlin and Cologne are sprinkled, among other things). ”In the“ collective presentation in book form ”, quotations from other authors are not always clearly differentiated from the author's opinion. Ewald Harndt found the title of the work - with which a Munich dentist had already headed his article in 1950 - not entirely logical: “So he wants to prevent tooth decay or prevent it from occurring by treating and curing it with fluorine. Even this not entirely logical version of the title expresses the fashionable overvaluation of the element. ”Caries researcher Klaus G. König criticized the second edition of the work, which was published in 1967 under the title“ Dental Caries Prophylaxis through Fluoride ”, even more violently. Schmidt simply took on himself with his self-imposed task. In addition to the many factual deficiencies, including medical malpractice in the procedure described for treating hydrofluoric acid burns, König criticized “misprints that can be found on every page” and the grammatical not always pure sentence structure. He saw himself “unable to recommend the book as a reference work on caries prophylaxis with fluorides”. Schmidt himself later described his book as a “standard work”, especially since the previously critical Karl-Michael Hartlmaier described “The truth about fluorine” in it saw.

First contacts with fluoride research

After isolated recommendations for fluorides to keep teeth healthy were made in the 19th century, fluorides were illegally used as food additives (preservatives) as well as rat poisons and insecticides at the beginning of the 20th century. They caused numerous poisoning and were therefore feared mainly because of their toxic effects until the end of the Second World War. Hermann Schröder from the Berlin Charité referred at the time to the “Poison Law of 1926”, which forbids the medical use of fluorides other than homeopathic dilutions of at least D4. Rudolf Wohinz (1896–1954), a colleague of Schröder, reported in 1949 that earlier requests to the Reich Health Office for permission to try sodium fluoride as a caries prophylactic were met with an “relentless no”. Hermann Euler , Oskar Eichler and Ewald Harndt also initially only saw the toxic side of fluoride. In 1949, Schmidt reported on his own animal experiments with fluoride feeding from 1944, although by then his view of the fluoride problem had already changed. It was not until 1947 that he received "new references to the eminent future significance of fluorine as a prophylactic" and saw it as an opportunity to collect and translate all the literature - a work that was mainly done by Hertha Hesse - to sift through and put together in order to " to make available to the gentlemen who can continue to work in this field through their experience and at the same time are able to counter an overestimation. "" I came from the toxicological side, "he wrote in 1969 in his somewhat idiosyncratic style," own experiments, animal experiments The nature, clinical nature, self-exposure and much more led me to believe that the beneficial effects of physiological fluorine administration were beneficial. ”This was due to the fact that, after the end of the Second World War, American dentists became famous in Germany for fluoride research.

From the point of view of the Americans, German dentistry was in a sorry state at the end of World War II, and to top it all off, the Fédération Dentaire Internationale (FDI) excluded Germany (and Japan) from membership in 1947. While censorship had already meant restrictions in scientific exchange during the war years, German dentistry was now isolated from the rest of the scientific world. The American status report states that German university professors had hardly noticed anything about the fluorine research carried out by American dentists. In 1947, the dentist Willy Geier from Stuttgart-Degerloch quoted the American report from a report in the Swiss Monthly for Dentistry : “Théories confuses partout. Ignorance du rôle des fluorures ”(Confused theories everywhere. Ignorance of the role of fluorides). He found this statement of the American military doctors confirmed to a certain extent by the work of the Swiss dentist Charles Leimgruber, who reported on his research in the same issue.

In the summer of 1948, visits from America , especially lectures by Joseph Francis Volker, who was perceived as a fluorine expert, brought a spirit of optimism with the prospect of a successful fight against dental caries with fluorine compounds at German universities in Frankfurt, Heidelberg, Munich, Tübingen and Berlin. Walter Drum was the first board member of the Dental Association at the University of Berlin, founded on June 17, 1948, who was enthusiastic about what his American colleagues heard and read. As early as 1949 he called for a vigorous start to the “hardening of mouthguards in all schools in Germany”, even if those who doubted first wanted to see evidence of the effectiveness of local fluoridation. From 1949 onwards, Schmidt wrote presentations on current German-language literature for drums Zahnärztliche Rundschau . One of his favorites among the Swiss authors was initially the Bern dentist Charles Leimgruber, who had been dealing with “fluorine and caries resistance” since 1946, but came to “a complete rejection of fluorine medication” in 1951 and was ultimately “a great illusion” " saw. Schmidt, on the other hand, was infected by drums enthusiasm. In January 1950, he said, as before Drum, that "the practice should continue to build on years of American experiments and that these experiments cannot be pushed aside by pointing out that they want to wait and see."

The German Fluorine Commission

On July 8, 1949, the formal founding of the German Committee for Youth Dental Care (DAJ) was chaired by Hans Joachim Tholuck , initiator of the Frankfurt system of school dental care. Within the DAJ, Tholuck, Schmidt and the Marburg dentist Wilhelm Kessler (1898–1987), a former SS-Obersturmbannführer from Aachen, founded the German Fluorine Commission on November 15, 1950 . Walter Drum, Hermann Euler, Heinrich Hornung , Oskar Eichler and Eugen Wannenmacher , among others, were invited as corresponding members . Kurt Maretzky , editor of the Zahnärztliche Mitteilungen , provided the DAJ and the Fluorine Commission with regular pages of his journal for progress reports, which Schmidt and Kessler alternately used for presentations. The number of so-called “extraordinary members” (manufacturers of fluoride preparations) quickly grew , supporting the work of the commission with material such as dental care sets, tablets, toothpastes, fluoride-containing chewing gum (patented for Kauvit by Adolf Knappwost ) and also financially. The German fluorine commission of the DAJ submitted its last report in March 1965 in the dental reports and then passed into a fluorine commission within the German Society for Dentistry, Oral and Maxillofacial Medicine (DGZMK), which will give an expert opinion on “current issues in fluorine research . ”The chairmanship of this short-lived commission was taken over by Rudolf Naujoks , who in this function (also Vice President of the ORCA) made a general recommendation of the TWF on behalf of the DGZMK in 1966. This endorsement was legitimized in October 1967 at the 94th annual meeting of the DGZMK within the framework of a controlled discussion under discussion leader Adolf Kröncke , which is otherwise unusual at these meetings . This signaled “complete unity among the experts”. At this time (1967–1971) Hans Joachim Schmidt was an assessor on the board of the DGZMK.

Foundation of the ORCA

Schmidt also tried to bring fluoride researchers together on an international level. It is thanks to a faux pas from Schmidt that he apparently founded a “ European Working Group for Fluorine Research ” as early as 1949 and named eight participants in a circular, whom he invited to actively participate. The fact that he cited the “inability of universities to perform scientifically due to factual and personal deficiencies” - Schmidt may have meant a lack of staff - as a reason, was annoying, in connection with the establishment of another association (“Institute for Caries Research and Orthodontics of the Württemberg Dental Association”) Hans-Hermann Rebel , head of the Dental Institute at the University of Tübingen, who then publicly criticized the fact that he was named as a participant on Schmidt's list without Rebels consent. Regarding the establishment of the above-mentioned working group, Schmidt later stated that at the beginning of 1953 he had received a letter from the Swiss dentist Hans Robert Held (1910–1998) “with the request to visit him to consider whether such a working group had been set up should be. ”Held was married to the owner of the factory that made the Zymafluor tablets. In 1950 he had already stated a “fluorine deficiency” in Switzerland and in 1952 reported in the Zyma Journal about his fluoride work, which concerned the passage of fluorine after fluorine medication during pregnancy and while breastfeeding. When Schmidt met Held on February 28th in Geneva, he had received the order to draft the first statutes for the new working group. For the constituent meeting in Konstanz in November 1953, the Austrians Sepp Koller and H. Leonhardt, the Germans Walter Drum, Hertha Hafer , Adolf Knappwost, Erwin Ott, Hans Heuser , and the Swiss H. Schmid and Victor Demole met alongside Held and Schmidt . The first congress of the European Working Group for Fluorine Research and Caries Prevention (EAFK) took place in Salzburg in 1954. It was there that Schmidt met the Swiss dentist Theo Hürny, who was president of the Swiss Dental Association from 1949 to 1952, and also a member and later president of the fluorine commission of the Swiss Academy of Medical Sciences.

The abbreviation ORCA for the working group was used for the first time at the 1956 congress in Marburg and Kassel. Close contacts between Held's family and the Swiss watch manufacturer Rolex enabled the establishment of the ORCA Rolex Prize for outstanding work in the field of caries research. In 1956, Rolex donated 30 gold wristwatches of the latest and most sophisticated design to reward the three best works of the next 10 congresses. The organization initially used the Archives of Oral Biology journal as the publication medium , then for a few years the lectures at the annual congresses were published in book form as Advances in Fluorine Research and Dental Caries Prevention , until Caries Research was finally established as a journal in 1967 . At the general assembly at the end of the 13th congress in Perugia (Italy) in June 1966, Rudolf Naujoks was elected as the organizer of the next congress (1967 in Würzburg) as co-president and Fritz Bramstedt was elected to the scientific advisory board. At the same meeting it was decided to change the name of the organization to European Association for Caries Research or European Organization for Caries Research (ORCA). The fact that "fluorine research" was deleted from the name initially stunned Schmidt. The intention of the founding members to completely clarify the fluorine research has by no means been fulfilled and the ("alleged") name change violates the statutes. Then he accepted the change and declared that it should send a signal: "The ORCA will no longer discuss such topics in the future," explained Schmidt. "The TWF has proven to be safe, harmless, technically feasible and cheap." Under the chairmanship of Rudolf Naujoks , the ORCA President elected in 1967, Walter Künzel gave a lecture in 1967 which Schmidt described as the "final line under the topic of drinking water fluoridation".

In his report on the congress in Perugia, Schmidt criticized the fact that German colleagues were only represented in small numbers. You should take the opportunity to gain academic qualifications and to contribute to progress. On the other hand, the ORCA lacks a “parallel event for the practitioner in which the new scientific findings from the previous year are presented to the practitioner. This was also the will of the founders, which they anchored in the constitutions. ”At the congress in Würzburg in 1967, almost half of the free lectures were given by German authors. As a result, arguments, personal insults, unscientific discussions as well as allegations that the work was not scientifically founded gave rise to some (founding) members to leave the ORCA disappointed, including Hans Joachim Schmidt. He wrote annoyed about loud voices accusing him of only letting the “fluorine advocates” have their say, that they “had neither dealt with the fluorine question for several years, nor had they ever used the documentation center. I don't know why they call themselves scientists , though . In particular, what one hears or reads from spontaneous scientists today is so bogus that one cannot comment on it either. ... Nowhere in the world does this judgment apply to unskilled workers. Nothing more is said here. "

Document center for dental literature

The collection of index cards on literature, which Schmidt had initially created as the basis for his dissertation and which he then continuously expanded - sometimes with the active (translation) help of Hertha Hafer, grew to a considerable dimension over time. His passion for collecting was first recognized in March 1951 when, on the recommendation of JM Ingendaay, he took over the presentation of the Anglo-American journals for the German Dental Journal . In January 1964 he was commissioned by the DGZMK to make the German-language literature continuously available to the American Dental Association (in the form of an annual file). In debates, he saw an advantage in the fact that his collection allowed him, according to Schmidt in a reply to a criticism by the editor of the Zahnärztliche Mitteilungen, to see the topic from a point of view that others cannot have. Discussions should be left “to those researchers who have been dealing with the problem for years and who know better how to assess success and failure.” As Schmidt explained in 1964, some time ago the 20,000. Filled sheet and the fluorine literature to have captured staple, grabbed Adolf Kröncke this as an argument against Fluoridierungsgegner on. In 1966 Schmidt had already lined up 23,100 index cards and convinced the previously critical editor Karl Michael Hartlmaier with the relatively few quotes processed in his new book Dental Caries Prophylaxis through Fluoride. Schmidt reported 25,000 index cards in 1967 and 26,000 a year later. After 28,470 index cards had been created, Schmidt discontinued the Fluorschrifttum booklets , as the work is now being recorded by DIMDI, the German Institute for Medical Documentation and Information . In 1971, Schmidt bequeathed his collection of around 30,000 index cards, around 1,000 original articles and over 100 books to the Federal Association of German Dentists (BDZ). From there, the documentation was moved to Vienna in 1980, where it was to be continued as the International Documentation Center for Preventive Dentistry by Kurt Binder (1919–1984) and Heinrich Newesely (1933–1993). Two hours before the center was officially opened on March 19, 1981, Hans Joachim Schmidt suffered a heart attack in Vienna and died.
