Moritz Wilhelm Drobisch

Moritz Wilhelm Drobisch (16 August 1802 – 30 September 1896) was a German mathematician, logician, psychologist and philosopher.

Drobisch made contributions to philosophical and mathematical logic, set theory, quantitative linguistics and empirical psychology.

In 1846 he was a co-founder of the Saxony's Royal Society of the Sciences, whose successor organisation has named a medal in his honour.

In his later years, Drobisch's blindness progressed, making scholarly work impossible from the mid-1880s on.

Wilhelm Wundt, a pioneer of German empirical psychology, held Drobisch's funeral oration and acknowledged his influence.
