sentences:  Earning great importance after the First World War were the local diamond-cutting workshops that arose in the area around Brücken, about 4 km south of Herschweiler-Pettersheim and the hub of the Palatine diamond-cutting industry, which gave rise to an economic upswing.The groundwork for this blossoming industry was laid for Herschweiler-Pettersheim in 1908 by Christian Schultheiß, who came from the German centre for diamond processing in Hanau, and who had been recruited in 1887-1888 by Isidor Dreyfuß for the newly founded diamond-cutting workshop at the "Neumühle" ("New Mill") between Ohmbach and Brücken.Further growth was cut short only a few years later when the First World War broke out, but this was only a temporary setback, and work began again in 1923.
