Here's an invention we all can appreciate. In the 1880s, Josephine Cochrane was dismayed when her household servants chipped her heirloom china while washing it by hand, and when she tried to do it herself, she realized there must be a better way. She was determined to develop a machine that could do it faster and more safely. Working in the shed behind her house with a local mechanic, she created the first dishwashing machine. She built wire compartments based on the size of the plates, cups, and saucers. Those compartments were placed in a wheel inside copper boiler. When a motor was turned on, the wheel turned and soapy water jetted onto the dishes. Josephine received the patent for the machine in 1886 and went on to sell them to hotels and restaurants. It wasn't until the 1950s that homes were designed with the time-saving machines, something every busy parent can truly appreciate.
