. Wц╤hler was the first in a pure form of very many substances: aluminum, amorphous boron, beryllium, yttrium, silicon carbide SiC and calcium carbide CaC2.
. Friedrich Wohler (1800-1882) - German chemist, was born in Esherheyme near Frankfurt in the family of the eminent burgher
. At the insistence of parents, he graduated from the Medical Faculty of the University of Marburg, and in 1823 received a doctorate in medicine - the surgeon.

. He proposed a new method for white phosphorus P4 by heating a mixture of calcium orthophosphate Ca3 (PO4) 2, coal and sand (silicon dioxide) SiO2. This method is still used in industry in almost all countries.
