Hans Lorenz-Meyer

Johannes Valentin "Hans" Lorenz-Meyer (born August 18, 1861 in Hamburg ; † September 5, 1947 there ) was a German civil engineer.

He took the name Lorenz-Meyer like his brother in 1903 (probably because his father and grandfather were called Lorenz Meyer).

Lorenz-Meyer grew up in Hamburg as the son of a businessman and, after graduating from high school, went to Berlin in 1880, where he studied civil engineering at the TH Berlin-Charlottenburg . He passed the 2nd state examination and joined the Prussian hydraulic engineering administration as a government master builder. First he was in Hildesheim , then in Opole and finally with the high presidium in Breslau . In 1897 he tried in vain to get into the electricity and port administration of Hamburg. Instead, he was a councilor and building officer in the administration of the Brandenburg waterways in Potsdam . Since he had acquired knowledge of the reinforced concrete, which was still new at the time, he was accepted as an assistant in the technical office of the Prussian Ministry of Public Works, which was headed by Wilhelm Germelmann . Germelmann commissioned him from 1910 to take care of the German Committee for Reinforced Concrete . After Germelmann's death in 1919, he was its director until 1921. Other tasks were urban development and expansion. For his achievements he was appointed a secret building officer. When responsibility for waterways passed to the German Reich, he managed the remaining tasks, now subordinate to the Ministry of Agriculture, and became Ministerialrat. In 1921 he took over the chairmanship of the moor committee and in 1924 he retired.

He worked on the manual for reinforced concrete construction and on the concrete calendar.
