Pfalz Flugzeugwerke was a World War I German aircraft manufacturer, located at the Speyer airfield in the Palatinate (German: Pfalz). They are best known for their series of fighters, notably the Pfalz D.III and Pfalz D.XII. The company went bankrupt after the Armistice, when the French occupation forces confiscated all of the equipment, but the factory was re-used by various other companies until re-forming in 1997. Today they are a parts manufacturer referred to as PFW.
Pfalz was the brainchild of Alfred Eversbusch, son of a foundry owner in Neustadt an der Weinstraße. It appears that he had built his own aircraft between 1912 and 1913, although the exact origin of the design is unclear. On June 3, 1913, the Pfalz company was registered, consisting of Alfred, his brother Ernst, and his brother-in-law Willy Sabersky-Müssigbrodt, as well as several investors: Richard and Eugen Kahn, and August Kahn (unrelated).
They initially proposed to build designs from Albatros, but their attempts at a deal amounted to nothing. Their next deal was with Gustav Otto Flugzeugwerke, building examples of his pusher-propeller biplane design. The original example was sent to Africa on a tour, and ended up being pressed into service as a scout.
The company had always planned to set up shop at the new airfield in Speyer, but they initially had problems securing land for a factory. The Gustav designs were actually built in the Speyer Festival Hall, which was unused at the time. It was not until February 6, 1914, that the city agreed to sell Pfalz 7,000 m² to build their factory. Construction was completed in July, only one month before the start of World War I.
By this point, the company had arranged a license to produce Morane-Saulnier monoplanes, which were quickly put into German service. When these became uncompetitive on the Western Front, Pfalz shifted production to the LFG Roland D.I and D.II. The D.II was produced into late 1916, by which point it too was no longer competitive.
