The discovery of natural gas around Findlay in 1886 started an industrial rush in northwest Ohio. Within five years, over 100 glass companies had moved into the region for free gas and railroad connections to the western markets. Unfortunately the gas ran out in just a few years, and many glass companies moved on, but those that stayed changed the nature of the glass industry forever. A brilliant inventor, Michael Owens of Libbey Glass automated the glass-making process after 3,000 years of no change. His automated bottle-making machine changed American life with the introduction of the milk bottle, beer bottle, glass jar, baby bottle, and soda bottle. It also eliminated child labor in the glass factories. Owens also automated the production of fl at glass by 1920. By 1930, over 85 percent of the world's glass was being produced on the machines of Michael Owens, bestowing the title of "Glass Capital of the World" upon northwest Ohio.
