The Romans were the first known to employ glass for windows, a technique that was most likely invented in Roman Egypt, in Alexandria, about 100 AD. Paper windows were inexpensive and popular in ancient China, Korea, and Japan. They were made from rice paper or hemp paper that was as thin as possible without breaking. In Europe, medieval castles and monasteries used latticed wooden shutters during winter months because they did not have glass. In 1160, the first recorded use of "glass" for a window came from England when it was described as a "light frame." In 1913, the first electric lights installed in a home opened the way for today's garage doors and open-air living rooms. The first U.S. house with glass windows may have been built by Joseph Dixon in 1765. However, these windows were panes of clear rock salt set into wooden frames and they offered no viewing vista. It wasn't until 1872 that the first true glass window panels were manufactured. They were sold by the New York City company Pratt & Lambert and were an instant success. Within a few years, other companies began making their own line of glass windows and by 1880, nearly all homes in America had adopted this modern feature. In 1882, Charles Franklin Kettering developed an electric bell system that could be controlled from a remote location.
