Bruno Albert Lange (born January 2, 1903 in Berlin ; † March 6, 1969 there ) was a German physicist and industrialist.

Life

After the early death of his parents, Lange lived as a child in East Prussia and went to school in Ortelsburg . In October 1921 he was then enrolled at the Albertus University in Königsberg , where he studied chemistry , physics , mathematics , mineralogy and philosophy . In the spring of 1925 he passed the second association examination and from then on worked as assistant to the physicist Wilhelm Eitel (1891–1979). As this to the director of the Kaiser Wilhelm Institute for Silicate Research in Berlin-Dahlem was appointed, Bruno Lange joined him and lived in Berlin from February 1926.

In 1927 Bruno Lange received his doctorate from the Philosophical Faculty of the Friedrich-Wilhelms-Universität Berlin under Privy Councilor Fritz Haber in physics on the subject of depolarization and light absorption in colloids . He continued researching this topic and gave a lecture on a new type of photocell on the occasion of the 6th German Physics Day in Königsberg from September 4th to 7th, 1930 .

In 1931 the physicists developed while working at the Kaiser Wilhelm Institute for Silicate Research selenium - photocell . With the aim of using this cell economically, Bruno Lange founded Dr. Bruno Lange GmbH . This soon showed its first successes and multiplied its profits by 1945. After it was dismantled by the Allies in 1945, Lange succeeded in leading his company to new heights. He managed the company until his death in 1969, after which his son Reinhard Lange took over this task.

The company founded by Bruno Lange is now part of Hach Lange GmbH and one of the world's leading manufacturers in the field of environmental analysis .

Bruno Lange married Frieda Nevieger from East Prussia in 1928. The two children Edelgard (* 1929) and Reinhard (* 1933) came from this marriage .

In 1948 Bruno Lange was a member of the founding committee of the Free University of Berlin .

Awards

He was awarded "Honorary Membership" of the Eugene Field Society USA for his work and was a member of the Max Planck Society . In 1951 Bruno Lange received the gold DECHEMA medal “For outstanding developments in innovative laboratory equipment” and in 1958 a bronze plaque for his contribution to the World Exhibition in Brussels in 1958 as part of the “Palais der Internationale Wissenschaft”.

Fonts

In 1936 Bruno Lange published the book Die Photoelemente und their application , which was considered a physical standard work for a long time. He also wrote the standard work Colorimetric Analysis , which was published in its fifth edition in 1956.
