biography

Kammüller graduated from high school in Lörrach in 1905 and first studied mathematics and physics at the University of Heidelberg and then civil engineering at the Technical Universities of Karlsruhe and Danzig. Afterwards he was assistant at the chair for mechanics at the TH Hannover . During the First World War he worked as an officer at the front on sound measurement technology (positioning for artillery), on which he received his doctorate in 1919 at the TH Hannover. In 1921 he became Emil Probst's assistant at the newly founded concrete institute of the TH Karlsruhe . He was also chief engineer at the Maier engineering office in Karlsruhe, where he designed the first dissolved arch dam in Germany, the Linach dam (Vöhrenbach dam). He then worked for the Lahmeyer electricity company in Frankfurt on the design of the Schluchseewerk and the Schwarzenbachtalsperre .

In 1927 he qualified as a professor ( The theory of gravity dams taking into account the more recent results of strength theory ) and in 1934 became professor for concrete and reinforced concrete construction at the TH Karlsruhe. His predecessor Emil Probst was expelled from his chair by the National Socialists in 1933 and went to England. Kammüller held the chair until 1956.

During the Second World War he worked again on sound measurement methods ( projectile cracking method ) for artillery.

He published a proposal for concrete cable-stayed bridges early on and even applied for a patent for it in 1950 (withdrawn in 1952), as did Franz Dischinger . Both were unsuccessful (Dischinger had already published about them).
