Rudolf Sendtner

from Wikipedia, the free encyclopedia

Rudolf Sendtner (born September 13, 1853 in Munich , † September 16, 1933 in Füssen ) was a German alpinist , food chemist , royal professor and second director at the royal research institute for food and beverages in Munich. He mainly made a name for himself in the area of drinking water hygiene.

Life

Rudolf Sendtner was one of four children from Theodor von Sendtner's first marriage with the wholesaler and magistrate's daughter Clothilde Negrioli. His half-brother was Ignaz Sendtner, a physician from his father's second marriage.

He studied at the Faculty of Philosophy , University of Erlangen and was there with his dissertation on the topic About some compounds of uranium on April 6, 1877 Dr. phil. PhD. In 1879 he conducted research with Casimir Wurster in Munich.

This was followed by postgraduate studies in chemistry with Max von Pettenkofer at the Ludwig Maximilians University in Munich in the winter semester of 1881/82.

From 1890 until her death on June 14, 1891, Rudolf Sendtner was married to Therese Geisreiter. On October 31, 1900 he married the concert singer Elisabeth Schmidt. However, both marriages remained childless.

Alpinism

Animated by his father, who liked to take his sons with him on mountain tours, Rudolf Sendtner was also an enthusiastic mountaineer . In 1881 for the magazine of the German and Austrian Alpine Club , he illustrated the Gimpel - Kölle group, which was still quite unknown at the time, in a report on his tour in the Tyrolean Tannheimer Mountains in 1879 . The Köllenspitze became better known through the ascents carried out in 1869 by Hermann von Barth and Sendtners in 1879 and 1884, especially through Sendtner's description.

Free association of Bavarian representatives of applied chemistry

In the spring of 1883, Sendtner was a founding member of the Free Association of Bavarian Representatives of Applied Chemistry , which was converted into the newly founded Free Association of German Food Chemists in August 1902 , which was renamed the Association of German Food Chemists in 1912 .

Among other things, it ensured that in 1884 the Association recognized the Reichert-Meissl research method for the detection of foreign fat additives in butter fat . In 1927, on the occasion of the 25th anniversary of the Association of German Food Chemists , Adolf Beythien named him among the association's "well-known names" alongside Max von Pettenkofer, Albert Hilger , Rudolf Emmerich, Anton Halenke and Franz von Soxhlet .

Royal Research Institute for Food and Beverage

Sendtner was particularly involved in the area of ​​drinking water hygiene. From 1880 to 1883 he examined the water quality of wells in Munich and, in comparison, also in Dillingen an der Donau . From the summer semester of 1883, Sendtner was II: Assistant to the examination center at the Pettenkofer Hygiene Institute at Findlingsstrasse 34 ; I. Assistant to the investigative body at that time was Rudolf Emmerich . In the summer semester of 1887, Sendtner became the first assistant to the investigative body.

In the winter semester of 1891/92 the Hygiene Institute was renamed the Royal Research Institute for Food and Beverage .

From 1889 he worked in Munich as first assistant at the Royal Research Institute for Food and Beverage in Munich. Promoted to Royal Inspector in the fall of 1892 , Sendtner headed the investigation of the water from 1,079 pump wells in Munich. In his final report in 1894, he stated: “Based on the results of the chemical analyzes of the wells in these parts of the city, it cannot yet be said that the soil in the inner city has actually been significantly cleaned over the past 30 years.” According to his analyzes, the nitric acid content of these well water was much higher in 1893 than in 1892.

From 1893 he published together with Rudolf Emmerich, Albert Hilger and Ludwig Pfeiffer the research reports on food and its relationship to hygiene, on forense chemistry and pharmacognosy .

In the winter semester of 1894/95 Albert Hilger took over the management of the research institute. In 1898 Sendtner was promoted to royal chief inspector. From the daily newspaper of a meeting of the Society of German Natural Scientists and Doctors in 1899 it emerges that he introduced the subject of food chemistry. In 1902 he signed the agreements for the uniform examination and assessment of food and luxury goods as well as everyday objects for the German Reich .

In 1903 he was awarded the professional title Royal Professor for his services .

After the summer of 1905, the university professor and later imperial secret government secretary Theodor Paul took over the management of the investigation institute.

Under his leadership, the positions were re-designated in 1906: Paul became first director and head director of the investigative institute, Sendtner second director and director and Paul's deputy.

In this function, Sendter was also a member of the commission established in 1909, which dealt with the writing of the 100th anniversary of the Polytechnic Society for the Kingdom of Bavaria in 1915.

At the beginning of 1916 he retired. To say goodbye to professional life, Sendtner Knight III. Class of the Order of Merit of St. Michael ., Which had been awarded to him in the fourth class in 1909.

In 1919, Rudolf Sendtner moved from Munich to Füssen. His three unmarried siblings Klothilde, Albrecht and Theolinde followed him a year later.
