Erich Lackner

Erich Friedrich Michael Lackner (born May 13, 1913 in Himmelberg ; † February 2, 1992 in Carinthia ) was a German engineer for civil engineering and hydraulic engineering of Austrian origin. For a long time he had a leading position in port and hydraulic engineering in Germany.

Life

Lackner graduated from high school in Klagenfurt in 1931 . In 1932 he joined the NS student union and the SA. He held the SA rank of a Rottenführer. In 1936 he was naturalized in Germany. After completing his studies and exams at the Technical University of Berlin , Lackner joined the engineering office Agatz & Bock, which had been founded a year earlier . On February 12, 1941, he married Ursula Ahlbrecht. At Agatz & Bock, Lackner was department head until 1943 and at the same time honorary assistant to Arnold Agatz at the Technical University of Berlin until his doctorate in 1942 ( calculation of multiple supported sheet pile walls ) . As a junior partner of the engineering office, from 1943 until the end of the war he was the site manager for the construction of the Valentin submarine bunker , one of the largest in Europe, commissioned by the Todt organization . When asked about his well-paid office work and the hard work of the forced laborers and concentration camp prisoners on the construction site, he said in a radio interview in 1981: "The working conditions were the same for everyone."

From 1945 to 1947 Lackner was a department head in the "Civilian Engineering Section" of the US port authority. The main focus of his post-war activities was the reconstruction of the war-damaged ports, and increasingly also activities abroad. After his patent for prestressed, anchored trough body soles from 1953, u. a. Dry docks built in Alexandria and Karachi .

After the war, Lackner was a junior partner and head of department in the Agatz engineering office, which moved to Bremen in 1945 . In 1971 the engineering office was renamed Lackner, Kranz, Barth, Beratende Ingenieure and from 1976 was called Lackner und Partner . In 1997 it was taken over by the Inros group of companies, and since 2004 Inros Lackner AG. You worked on numerous projects around the world, particularly in port construction. For a selection of the office's projects, see the Arnold Agatz article .

From 1964 to 1980 Lackner was a full professor at the chair for foundation engineering, soil mechanics and hydraulic power engineering at the University of Hanover and director of the Institute for foundation engineering and soil mechanics at the University of Hanover. Lackner published numerous technical and scientific publications in German and English.

In 1965, Lackner founded the Erich Lackner Foundation for the “promotion of talented, needy young people born in Carinthia”.

For several decades since its foundation in 1949, Lackner had been the chairman of the working committee for embankments of the Hafenbausechnische Gesellschaft and regularly published its recommendations (EAU, published by Ernst & Sohn). He was also on many other committees, for example he chaired the investigative committee that investigated the dam breach in the Elbe Lateral Canal in 1976 and the committee that investigated the breach in the Main-Danube Canal in 1979 , which the Lackner engineering office then ran across its entire length carefully examined.

The Hafenbautechnische Gesellschaft eV (HTG) has been awarding the Erich Lackner Prize, named after him, to young engineers every two years since 1993 . This prize is intended to honor “outstanding contributions from science and practice”. Lackner was chairman of the HTG for many years .
