The Red Wing Project on Utilization of Electricity
Society: ASABE Main Category: Agricultural & Biological Sub Category: Mechanization Era: 1920s DateCreated: 1923 Goodhue County Historical Society Red Wing State: MN Zip: 55066 Country: USA Website: https://www.asabe.org/awards-landmarks/asabe-historic-landmarks/the-red-wing-project-on-utilization-of-electricity-in-agriculture-53.aspx Creator:

The object of the Red Wing project was "To determine the optimum economic uses of electricity in agriculture and to study the value of electricity in improved living conditions on the farm." Although not the first service to farms in the U.S., it was likely the first built as an experiment specifically for collecting and publishing engineering and economic data.

Corn Silage Harvester
Society: ASABE Main Category: Agricultural & Biological Sub Category: Equipment, Harvesting and Baling Era: 1890-1899 DateCreated: 1892 Biosystems and Agricultural Engineering Building Falcon Heights State: MN Zip: 55108 Country: USA Website: https://www.asabe.org/awards-landmarks/asabe-historic-landmarks/corn-silage-harvester-26.aspx Creator:

Charles C. Fenno Of Grinnell, Ia, Patented The First Field Corn Silage Harvester On April 19, 1892. His Ground-Powered Machine Cut The Corn Plant And Fed The Tassel End First To A Rotary Cutter. Joseph Weigel Of Flandreau, Sd, Improved Fenno's Harvester In 1912 By Adding An Engine To Power The Cutter And By Feeding The Stalks Butt End First. Andrean And Adolph Ronning, Farmers Of Boyd, Mn Patented Further Improvements In 1915. In 1918 The American Harvester Co. Of Minneapolis, Mn, Began Manufacturing The Horse-Drawn Ronning Harvester Using Weigel's Patent Too.

Izaak Maurits Kolthoff
Society: ACS Main Category: Chemical Sub Category: Frontiers of Knowledge Era: 1930s DateCreated: University of Minnesota Minneapolis State: MN Zip: Country: USA Website: https://www.acs.org/content/acs/en/education/whatischemistry/landmarks/kolthoff-analytical-chemistry.html Creator: Kolthoff, Izaak Maurits

Izaak Maurits Kolthoff (1894–1993) has been described as the father of modern analytical chemistry for his research and teaching that transformed the ways by which scientists separate, identify, and quantify chemical substances. Once a collection of empirical recipes and prescriptions, the field of analytical chemistry is today an essential branch of chemistry built upon solid theoretical principles and experimental techniques, the basis of which was formed over the course of Kolthoff’s nearly 80-year career.

Peavey-Haglin Concrete Grain Elevator
Society: ASCE Main Category: Civil Sub Category: Buildings Era: 1900-1909 DateCreated: 1900 5505 Minnesota 7 Service Rd St. Louis Park State: MN Zip: 55416 Country: USA Website: http://www.asce.org/project/peavy-haglin-concrete-grain-elevator/ Creator: Peavy, Frank , Haglin, Charles

No image dominates the Midwestern landscape like the monolithic grain elevator, whose present shape and construction owe much to grain company operator Frank Peavy and architect-builder Charles Haglin.

Wanting to improve on the flammability and cost of traditional wood-cribbed construction, Peavy speculated that reinforced concrete, in its infancy at the turn of the century, would outperform other materials. But critics feared that the elevator would collapse due to the vacuum created when grain was emptied from the air-tight structure.

The refrigeration units placed on trucks in 1938 by Thermo King Corp. revolutionized the transportation of perishable foods. Today they are a common sight on streets everywhere. Consumer demand for meat, poultry, produce and dairy products increased at an astounding rate. These installations and subsequent ones on refrigerated vehicles, ships, and railroads have had worldwide impact on the preservation of food and other perishables during distribution.
