A richly illustrated history of the flour factories that transformed the milling industry worldwide-and forever changed the culture and architecture of Minneapolis

Among the most consequential advances of the Industrial Revolution was the invention of the modern roller mill, which sent the traditional millstone into obsolescence and fundamentally changed the production of a key ingredient to feeding the world. The culture and landscape of its hometown, Minneapolis, Minnesota, was altered as well, and Making Mill City tells the story of how revolutionary technologies originating at St. Anthony Falls on the Mississippi River put Minneapolis on the map and cemented its world status as "Mill City."

With deep historical detail and abundant illustrations, Robert M. Frame III charts the dramatic transformation of Minneapolis milling-and urban life-between the early 1870s and 1920s. Two machines propelled this change: the middlings purifier and the modern roller mill. Enabling millers to grind hard Upper Midwestern spring wheat, these innovations gave rise to the "mammoth mills" and ever-expanding flour factories that would soon dominate the Minneapolis riverfront. Prominent entrepreneurs like those who gave their names to the Washburn and Pillsbury A Mills were significant, but Frame foregrounds the crucial roles of the millers, millwrights, and engineers who designed and equipped the massive new factories, as well as the editor of the legendary weekly trade publication Northwestern Miller, to paint a picture of the vibrant culture that grew around this industrial phenomenon.

A rich narrative describing how Minneapolis became the largest producer and exporter of wheat flour for more than fifty years, Making Mill City captures a critical chapter in the history of the city. Art and architecture inspired by mills and millers stand today as National Historic Landmarks, and the development and success of the current thriving metropolis have strong foundations in its milling history.
