Acetylene had many uses at the time of the First World War, because it burned with a hot and luminous flame mainly. The oxyacetylene apple and the period of the oxyacetylene car company and bicycles made this good represent well. In an attempt to find a route to acetylene other than through calcium carbide, a Prest-O-Lite sponsored research by George O. Curme of the Mellon Institute in Pittsburgh. Ethylene research was directed towards converting gases for refining petroleum methods, led to more polyethylene material for acetylene production. Viewed from today's perspective, the Curme route to petroleum-based ethylene ranks as an important discovery. However, this was not the case at the time, because ethylene had almost no use before 1920. Curme's second major contribution was the research he carried out to see what useful products he could make with ethylene. The first was ethylene glycol, which became Prestone antifreeze. Others follow and now ethylene is evidently the most…

- The 1995 Nobel Prize in Chemistry was shared by Paul Crutzen, F. Sherwood Rowland, and Mario Molina for their work concerning the formation and decomposition of ozone in the stratosphere.
