10. Dishwasher
Josephine Cochrane was the inventor of the first commercially successful automatic dishwasher. She designed the dishwasher in the shed behind her home and then constructed it engaging the assistance of a mechanic, who later became one of her first employees.
Josephine Cochrane was a wealthy woman born in 1839. She was frustrated and annoyed by the fact that her servants kept chipping her fine china while washing it, so she came up with an idea and a design for an automatic dishwasher. In 1893, she presented her dishwashing machine at the Chicago World’s Fair.
