The life of Freidrich Wohler
Friedrich Wöhler was a German Chemist who was born in 1800 in Eschersheim, Prussia. In 1820, he started his studies in the field of medicine at Marburg University but he was very soon transferred to another university that is the University of Heidelberg. In 1923, his M.D. was received by him and then he started studying chemistry. It was for more than a year that he studied in Stockholm with a very well-known chemist, Jöns Berzelius. Inorganic Chemistry caught him by interest at that time.

Calcium Carbide
Calcium Carbide was discovered in the year 1828. This chemical is used for carbide lamps.
Eschersheim,Germany
Eschersheim is a city district of Frankfurt am Main, Germany. This is where my scientist was born.

Calcium Carbide
The high temperature required for this reaction is not practically achievable by traditional combustion, so the reaction is performed in an electric arc furnace with graphite electrodes. The carbide product produced generally contains around 80% calcium carbide by weight. The carbide is crushed to produce small lumps that can range from a few mm up to 50 mm. The impurities are concentrated in the finer fractions. The CaC2 content of the product is assayed by measuring the amount of acetylene produced on hydrolysis. As an example, the British and German standards for the content of the coarser fractions are 295 L/kg and 300 L/kg respectively (at 101 kPa pressure and 20 °C temperature). Impurities present in the carbide include phosphide.
