Carl Wilhelm Bernhard Scheibler (16 February 1827 – 2 April 1899) was a German chemist. Scheibler's research focused on sugar, including the technical chemistry of sugar production and the composition of

In 1866 Scheibler founded the ''Zuckerchemische und technische Laboratorium'' (Laboratory for sugar chemistry and technology) in Berlin, which was financed by the Verein der Deutschen Zuckerrübenindustrie (Association of the German

Gewerbeakademie Berlin and at the
University of Agriculture Berlin and he also was a member of the imperial patent office in Berlin between 1877 and 1882.
After a conflict with the Verein der Deutschen Zuckerrübenindustrie in 1882, he only worked privately at his institute, but he was able to patent several inventions in that time. For example, he helped his relative

His most influential patents were based on the technical production of sugar from beets. The crystallisation of sugar from molasses was difficult and therefore the sugar had to be separated from the molasses. In 1863 Scheibler invented the
