Philipp Holzmann
Philipp Holzmann AG was a German construction company based in Frankfurt am Main. The company was founded in 1849 by Johann Philipp Holzmann (1805-1870) in Sprendlingen near Frankfurt am Main as Philipp Holzmann & Cie. Initially the company was concentrating on railway construction, but then began to expand into building construction and civil engineering. In the late 19th century the company experienced rapid growth. The first large building contract was the construction of the Amsterdam Centraal railway station in 1882. This followed by the opera house in Frankfurt am Main, the law courts of Munich, the city hall in Hamburg and several railway projects in East Africa and Asia. In 1917 Philipp Holzmann & Cie merged with the Internationale Baugesellschaft and became the publicly traded Philipp Holzmann Aktiengesellschaft.
The company was liquidated in 2002. At its peak in 1994 the company had 43,000 employees and was with a revenue of 13.1 billion DM the largest German construction company.
