Kemna

KEMNA BAU Andreae GmbH & Co. KG is one of the largest German construction companies and the largest street infrastructure provider in Germany with its headquarters inside the country. The company was originally founded under the name of J.Kemna/Breslau and was a Steam engine, steam tractor, locomotive, steam plow, road roller and tractor factory in Wroclaw, part of Germany until 1945. It was one of Germany's largest producers in this industry and the largest steam-plow producer in Europe during the early 21st century. History J. Kemna - Breslau The company founder Julius Kemna originally came from Barmen, where he was born in 1837. In 1867 he started his business in Breslau (Silesia), which initially produced agricultural machinery. He worked with Fowler at times, but soon decided to build his own locomotives and steam plows. Following the example of Fowler, Kemna also built single-cylinder saturated steam engines, but soon recognized the advantages of high-pressure steam technology with superheated steam technology with compound or composite design, capable of significantly higher outputs with less consumption of heating material and water. With a keen sense for future developments, Kemna had recognized that the steam engine was not only revolutionary for industry, but also in agriculture and road construction. Julius Kemna died in 1898 and bequeathed 30 marks to his employees for each year of employment; enough money for many to build a house. In 1908 Kemna Bau presented a further development of the compound system: a superheated steam plow locomotive with overpowered steam and two high-pressure cylinders. 20th Century At the beginning of the 20th century, Julius Kemna became the "leading steam plow company on the European continent and entered the monopoly of English companies on the world market". The company developed into a "large industrial enterprise" around the turn of the century. Due to capacity expansions in 1905, approximately 900 employees were employed on a 52,000 m² industrial site.
