Cornelis Hendrik Edelman
Cornelis Hendrik "Kees" Edelman (29 January 1903 – 15 May 1964) was a Dutch geologist and soil scientist who worked at the Agricultural College in Wageningen. He is credited with popularizing the use of the so-called Edelman soil auger to study soil profiles. Using studies of soil profiles he compiled a very high resolution soil-types map of the Netherlands. Edelman was born in Rotterdam to teacher Hendrik Cornelis and Maria Catharina van Schoonneveldt. After schooling in Rotterdam he obtained a diploma in mine engineering from Delft and worked on petroleum geology briefly. He then joined as a curator at the Geological Institute of the University of Amsterdam. He examined the diffusion of heavy minerals and worked on sediment petrology for which he received a doctorate in 1933. He then became a professor of mineralogy, petrology, geology, and agroecology at the Wageningen Agricultural College where he succeeded Johan van Baren. He worked across the Netherlands with Willem A. J. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earth Auger
An earth auger, earth drill, or post-hole auger is a drilling tool or machine used for making holes in the ground. It typically consists of a rotating vertical metal rod or pipe with one or more blades attached at the lower end, that cut or scrape the soil. History Metal augers have been in use since the Middle Ages to drill holes in wood. In the 19th century, the hand-operated earth auger became a common farm and construction tool in the US, and several inventors submitted patents for them.US Patent Office (1881): ''Annual Report of the Commissioner of Patents'', page 251. The page lists several patents for "earth auger" or "post hole auger", including: 225,508 (A. J. Collins, 1880-03016), 226,444 (D. P. Cudd, 1880-04-13), 228,044 (A. J. Dine, 1880-05-25), 230,830 (E. A. Smith, 1880-08-03), 231,775 (J. S. Dunning, 1880-08-31), 232,041 (B. Knopp, 1880-09-07), and 233,931 (M. M. Hubby, 1880-11-02). An example is the design of a certain M. Hubby of Maysfield, Texas, consistin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotterdam
Rotterdam ( , , , lit. ''The Dam on the River Rotte'') is the second largest city and municipality in the Netherlands. It is in the province of South Holland, part of the North Sea mouth of the Rhine–Meuse–Scheldt delta, via the ''"New Meuse"'' inland shipping channel, dug to connect to the Meuse first, but now to the Rhine instead. Rotterdam's history goes back to 1270, when a dam was constructed in the Rotte. In 1340, Rotterdam was granted city rights by William IV, Count of Holland. The Rotterdam–The Hague metropolitan area, with a population of approximately 2.7 million, is the 10th-largest in the European Union and the most populous in the country. A major logistic and economic centre, Rotterdam is Europe's largest seaport. In 2020, it had a population of 651,446 and is home to over 180 nationalities. Rotterdam is known for its university, riverside setting, lively cultural life, maritime heritage and modern architecture. The near-complete destruction ...

Johan Van Baren
Johan van Baren (18 April 1875 – 7 February 1933) was a Dutch agricultural scientist who specialized in soil science. His most influential work was on the soils of the Netherlands ''De bodem van Nederland'' (in two volumes 1907, 1927). His son Ferdinand Alexander van Baren (1905-1975) also became a soil scientist. Van Baren was born in Rotterdam. He was an assistant to Jacobus Lodewijk Conradus Schroeder van der Kolk, J. L. C. Schroeder van der Kolk (1865-1905) from 1899 at the Delft University of Technology, University of Delft. From 1903 he taught mineralogy at the Wageningen University & Research, Wageningen Agricultural College and became a professor of mineralogy, geology, and agrogeology when it was made into a university in 1918. He wrote a biography of Winand Carel Hugo Staring, W.C.H. Staring (1808-1877). He was a founding member of the Geological Society of the Netherlands and Colonies.
