    THERMAL CRACKING PATENT
    January 7, 1913 - U.S. patent (No.1,049,667)

    A U.S. patent for the thermal cracking of crude oil was issued to William Merriam Burton (No.1,049,667). A crude petroleum mixture of various hydrocarbons can be separated into several groups of constituents by physical means, commonly distillation. His thermal cracking process used high heat and high pressure to chemically break longer molecules of less volatile components into smaller molecules, more than doubling the yield of gasoline which was much needed to fuel the motor industry. In its first 15 years of use the process saved more than 1 billion barrels of crude oil. In 1937 the invention of catalytic cracking superseded the Burton process, but it remains in wide use.

    DAGUERRE PHOTOGRAPHIC SYSTEM
    January 7, 1839 - Académie des Sciences, Paris

    Louis Daguerre made the first announcement of his photographic system at the Académie des Sciences in Paris, though details were not presented until 19 Aug 1839 when the process was announced publicly. By that time, the French government had bought the rights to the process from him, and then made them freely available to the world. However, this process had also been patented in England and Wales on 14 Aug 1839 - only five days previously.
