Friedrich Dolezalek (born February 5, 1873 in Sziget , Hungary , † December 10, 1920 in Berlin ) was an Austro-Hungarian or German chemist and professor of physical chemistry at the Technical University (Berlin-) Charlottenburg .

Life

The family of the railway construction engineer Karl Dolezalek moved to Göschenen in Switzerland shortly after the birth of their son Friedrich with their older son Carl Anton Vincens . There, Karl Dolezalek was involved in the construction of the Gotthard tunnel . In 1877 Karl was appointed professor at the Technical University of Hanover . Friedrich attended the Realgymnasium in Hanover until 1893 .

He then studied chemistry and electrical engineering at the Technical University of Hanover until 1895. He moved to the Georg-August-Universität Göttingen , where he studied physical chemistry and electrochemistry until 1897. For the next three years he was assistant to Walther Nernst , who later won the Nobel Prize, and received his doctorate there in 1898 on the subject of the thermodynamic theory of homogeneous mixtures . This was followed by a number of shorter employment relationships: from 1900 to 1901 he was a research assistant at the Physikalisch-Technische Reichsanstalt , then at Siemens & Halske , where he improved the Pupin coil and the construction of high-frequency machines until 1904 . In 1902 , Friedrich Dolezalek completed his habilitation at the Technical University of Charlottenburg and in 1904 was appointed as a lecturer at the newly founded Technical University of Danzig .

As early as 1905 he moved back to the University of Göttingen, where he took over the provisional management of the Institute for Physical Chemistry as Nernst's successor. Two years later he moved to the Technical University of Charlottenburg, where he was appointed full professor for physics and physical chemistry in 1907, and from 1913 for physical chemistry and electrochemistry. After the beginning of the First World War he was assigned as an officer to the engineering committee and worked there on listening devices for mining noises and new methods of finding ores.

After the war, Friedrich Dolezalek continued the interrupted development work for the electrochemical institute and died shortly after it opened due to illness. His grave is in the south-west cemetery Stahnsdorf .

Dolezalek was first married to Helene Samwer (1873-1908), a daughter of Karl Samwer , since 1900 . In 1910 he married Paula Maria Bomhoff († 1955), a daughter of the building contractor Johann Bomhoff in Westerland (island of Sylt ), and had two sons and a daughter with her, including Alexander Dolezalek (1914-1999).
