Claude Allen Porter Turner

from Wikipedia, the free encyclopedia

Claude Allen Porter Turner (* 4. July 1869 in Lincoln (Rhode Iceland) ; † 10. January 1955 in Columbus (Ohio) ) was an American civil engineer and designer of some important buildings in the three US - states of Iowa , Minnesota and Wisconsin in the American Midwest .

Turner began studying engineering at Lehigh University in Bethlehem, Pennsylvania , which he successfully completed in 1890.

After completing his studies, he worked for various companies in the eastern United States before moving to Minneapolis ( Minnesota ) in 1897 , where he founded his own company in 1901. On June 11, 1907, he received a patent for an innovative, flat- slab support system based on reinforced concrete , called the Turner system, known in German-speaking countries as the Pilzdecke . Although this patent was invalid in 1915 and 1916 in favor of a similar patent by the American engineer OW Norcross, Turner had foreign patents such as Hugh Ralston Crawford (1876-1954) in Australia. In total, Turner had around 30 patents licensed during his creative period.

Turner finally helped reinforced concrete make its breakthrough in the USA in the first third of the 20th century. In his older work he dealt with questions of natural philosophy, in particular the natural philosophical foundations of strength theory in the form of elasticity theory, physics, chemistry and cosmology.
