Background
William de la Barre, son of Carl and Josephine (Friedl) de la Barre, was born in Vienna, Austria.
William de la Barre, son of Carl and Josephine (Friedl) de la Barre, was born in Vienna, Austria.
In 1863, he entered the Polytechnic Institute in Vienna (now known as Vienna University of Technology), where he studied for two years before being recruited into the Austrian Navy as a machinist.
In the Navy, he received his first mechanical experience and training. De la Barre immigrated to the United States in October 1866, landing in New York, then settling in Philadelphia, Pennsylvania where he found employment as a draftsman and engineer He served as engineer for the Centennial Exposition held in Philadelphia in 1876.
They had three children.
In 1878, he and his family moved to Minneapolis, Minnesota. He became a salesman for Behrns" Exhaust, a patented apparatus for the prevention of dust explosions in flour mills, and for several years sold and installed this apparatus in various mills in Minneapolis.
While at the Centennial Exposition in Philadelphia, de la Barre had learned that a new process for milling flour had been invented in Europe that involved passing the grain through a series of rollers, rather than the large round millstones used in America. Washburn sent him to Europe to learn about the process firsthand.
What de la Barre discovered was that in Hungary, the mills were using large porcelain rollers shaped more or less like rolling pins and that each series of rollers ground the grain finer and finer.
On his return to Minneapolis, de la Barre designed rollers made from steel instead of porcelain. Using de la Barre"s steel rollers, the Washburn-Crosby Mills could mill flour that was cleaner, more uniform, and with less energy than ever before. The process was no less than a revolution in milling.
