Lunge, Georg

(b. Breslau, Prussia [now Wroclaw, Poland], 15 September 1839; d. Zurich, Switzerland, 3 January 1923)

chemistry, chemical technology.

Lunge was the son of a merchant. At the age of seventeen he graduated at the head of his class from a Gymnasium in Breslau. Subsequently, at the University of Breslau, he studied the natural scienc especially chemistry, and in 1859 obtained his doc torate magna cum laude with a dissertation entitled De fermematione alcohoica. He first studied under Lowig and Cohn, then with Bunsen and Kirchhorff at Heidelberg. In 1860 Lunge joined the chemical industry, initially as a chemist at a Silesian fertilizer factory. In 1862 he opened his own plant for the production of potassium ferrocyanide, ammonia, lead salts, and tartaric acid: but the venture was unsuccessful.

Lunge then went to England, where he first worked in a factory producing coal-tar products. In 1865 he joined the newly founded, small alkali works of Baily, Bowron & Co., in South Shields, first as chemist and subsequently as manager. Lunge married a Miss Bowron, daughter of one of his employers. He participated in the founding and activities of the Newcastle Chemical Society; established contacts with representatives of science and industry; and established a line reputation as a specialist in chemical technology. On the recommendation of Heinrich Caro, Lunge was invited in 1875 to become professor of technical chemistry at the Eidgenossische Polytech-nikum Schule in Zurich. Subsequently he was granted Swiss citizenship. He resigned his teaching post atZurich in 1907 but continued to write and do laboratory work until 1916. He retired at the age of seventy-seven.

At a time when most chemists worked in organic chemistry, Lunge was among the few who chose inorganic chemistry as a field of concentration. He was eminently pragmatic; Haber said of him that he had awakened spirits and conquered problems in applied science which previously had been dealt with only by technicians. Lunge worked toward the control of manufacturing processes by means of refined technical-chemical investigations and analyses and by the quantitative analysis of synthetic compounds. His vast technical knowledge based on practical experience made him a master in applying scientific results to economic-technical problems.

Lunge published an enormous number of papers. A bibliography he compiled himself—although not complete— lists eighty-six books and pamphlets as well as 590 articles. Practitioners acclaim Lunge’s works as particularly dependable, detailed, precise, and practical, the general approach being coupled with the explanation of the scientific principles involved. Lunge’s Handbuch der Sodaindustrie, his Steinkohlenteer and Anttnoniak, and his Chemischtechnische Untersuchungsmethoden (written with Ernst Berl) were for decades considered standard works for the chemical raw-materials industry.

Experimental work by Lunge and by many of his pupils treated all problems of chemical manufacturing, especially that of soda, sulfuric acid, chlorine, and chloride of lime, nitric acid, phosphates, coal-tar products, explosives, cellulose, and synthetic fibers. It resulted in several inventions, such as Lunge’s plate towers (which used countercurrents) for the acid industry and Heumann’s synthesis of indigo.

Lunge also personally directed a large chemical laboratory—in addition to his lecturing—in which students learned to test raw materials and to supervise manufacturing processes. The newly constructed chemical laboratory complex (built in 1883 in association with Victor Meyer) became the model for chemical-technical research and teaching facilities.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
