Acetylene of 180°. Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was rediscovered in 1860 by French chemist Marcellin Berthelot, who coined the name "acétylène". Berthelot's empirical formula for acetylene (CH), as well as the alternative name "quadricarbure d'hydrogène" ("hydrogen quadricarbide"), were incorrect because chemists at that time used the wrong atomic mass for carbon (6 instead of 12). Berthelot was able to prepare this gas by passing vapours of organic compounds (methanol, ethanol, etc.) through a red-hot tube and collecting the effluent. He also found that acetylene was formed by
USS Wave (1836) USS Wave (1836) USS "Wave" was a schooner in commission in the United States Navy from 1836 until probably 1846. "Wave" was a schooner-rigged yacht designed along pilot boat lines by John C. Stevens and built for him in 1832 at New York City by Brown and Bell. The U.S. Navy purchased her in 1836 for use in the Second Seminole War. In that campaign, she cruised the Florida coast in support of United States Army operations until 1840. After 1840, "Wave" served as a surveying vessel along the United States East Coast under the command of Lieutenant John R.
