Schmidt, Wilhelm
SCHMIDT, WILHELM (1868–1954), German anthropologist and Roman Catholic priest, was born on February 16, 1868, in Hörde (now Dortmund-Hörde) Germany, the son of a factory worker. In 1883 he entered the missionary school in Steyl, Netherlands, that served as the motherhouse of the Societas Verbi Divini (the Society of the Divine Word), which was founded in 1875. There he completed his secondary philosophical and theological studies, and he was ordained a priest in 1892. He studied Semitic languages at the University of Berlin from 1893 to 1895. In 1895 Schmidt was appointed professor of several theological disciplines at the Society of the Divine Word Mission Seminary of Saint Gabriel in Mödling, Austria (established 1889).
Various questions and problems of missionaries (especially from New Guinea) prompted Schmidt to undertake studies in linguistics, ethnology, and comparative religion. In 1906 he founded Anthropos, as international review of ethnology and linguistics, and in 1931 he established the Anthropos Institute in Mödling, an organization affiliated to the Society of the Divine Word, and he served as the institute's director until 1950. (In 1962 the institute relocated to Sankt Augustin, near Bonn.) From 1921 until 1938

Schmidt hammer
Type of measuring instrument
A Schmidt hammer,[1] also known as a Swiss hammer or a rebound hammer or concrete hammer test, is a device to measure the elastic properties or strength of concrete or rock[2], mainly surface hardness and penetration resistance. It was invented by Ernst Heinrich Wilhelm Schmidt, a Swiss engineer.[3]
The hammer measures the rebound of a spring-loaded mass impacting against the surface of a sample. The test hammer hits the concrete at a defined energy. Its rebound is dependent on the hardness of the concrete and is measured by the test equipment. By reference to a conversion chart, the rebound value can be used to determine the concrete's compressive strength. When conducting the test, the hammer should be held at right angles to the surface, which in turn should be flat and smooth. The rebound reading will be affected by the orientation of the hammer: when used oriented upward (for example, on the underside of a suspended slab), gravity will increase the rebound distance of the mass, and vice versa for a test conducted on a floor slab. Schmidt hammer measurements are on an arbitrary scale ranging from 10 to 100.
Schmidt hammers are available from manufacturers in several different energy ra
