Josephine M. (Garis) Cochrane (born March 8, 1839 in Ashtabula County , Ohio , † August 3, 1913 in Cook County, Illinois ) from Shelbyville (Illinois) is considered to be the inventor of the first usable dishwasher . Joel Houghton received the first patent for a device of this type as early as 1850, but it proved to be barely functional and was not widely used.

Her father John Garis was a civil engineer, her great grandfather was the inventor John Fitch . On October 13, 1858, she married the clerk and politician William A. Cochran (1831-1883). After getting married, she Europeanized her last name by adding an -e to it.

Invention of the dishwasher

As a wealthy woman, Cochrane regularly threw parties, but was annoyed that her employees damaged or broke valuable dishes while doing the dishes. Washing the dishes herself soon became a nuisance and she began to develop a device for this task. After her husband's death in 1883, she commissioned the railroad mechanic George Buttler to implement her designs.

The machine consisted of a watertight copper kettle in which the dishes were placed on wire baskets. Initially in manual operation, later with a motor, the baskets were moved on an impeller so that the soapy water flowing in via nozzles was evenly distributed.

On December 28, 1886, the dishwasher was patented in their name. At the Chicago World's Fair in 1893 , Josephine Cochrane received the award for "the best mechanical design, durability and suitability for use".

Her first machines were built by a contract manufacturer in Indiana, with whom she soon fell out. She founded the Cochran's Crescent Washing Machine Company , which later went up in Hobart . Customers were initially restaurants and hotels. In 1949 Hobart introduced a model for domestic use.
