Life

family

Kurt Lüer was the brother of Otto Lüer and Hermann Lüer as well as the son of the actuary Georg Christian Ludwig Lüer and Sophie Caroline Marie, née Jansen. In 1889 he married Helene, the daughter of the rent master Gustav Friedrich Otto Sievers and Anna Wilhelmine Eleonore, née Herbst, who worked there in Vilsen . His son was Hans Lüer .

Career

Born in the Kingdom of Hanover , Kurt Lüer completed an apprenticeship as well as a degree in pharmacy and then first ran a pharmacy in Wittingen near Gifhorn , then in Berlin-Charlottenburg . As a pharmacist, he was familiar with the tar preparations ( remedies ) obtained from bitumen and ichthyol . Shortly after the turn of the 20th century, he took note of the activities of the Swiss doctor Ernest Guglielminetti , "who had laid the first 40 meters of road tar to dust the streets in Monte Carlo in 1902 " and began his own research into road construction. In 1905 he took over the tar macadam method and built "using the method of the Swiss Heinrich Aeberli " from 1906 to 1914 road surfaces with raw tar in several places of the German Empire . He recognized the need for further research to improve the use of raw tar, tar pitch from hard coal and high- boiling tar oil as road tar. In the meantime he had founded the Aeberli-Teer-Makadam-Gesellschaft in Berlin in 1912 , which he later relocated to Hanover and converted into the Idera Society .

After an interruption due to the First World War  - at the beginning of the Weimar Republic , road construction was already more advanced in other countries - Kurt Lüer now wanted to develop "inexpensive road construction methods [...] himself that would help overcome the backward traffic conditions on German country roads". For his project could Lüer 1918, the Society for Teerverwertung in Duisburg-Meiderich win, and founded, together with Adolf Spilker , the Society of Tar road mbH Hannover , whose management he took over. With modest means, Lüer has now developed a tar suitable for road construction and the associated machines for laying it : “After he recognized the relationship between the amount of binder and voids in the rock structure as important for the quality and service life of bitumen top layers with few voids ,” he agreed to add binder and the grain structure of the mineral mixture [...] so that there are enough cavities left in the pavement even under load. ”With the development of new tar and new paving methods, Lüer finally invented the tar sand wearing course for road construction.

Kurt Lüer joined the society in the year the Study Society for Automobile Road Construction was founded in 1924, and in the following year he formed the working committees for tar roads and road machines .

Kurt Lüer died in Sigmaringen a few months after the end of the Second World War .
