Otto Unverdorben (October 13, 1806 - November 28, 1873) was a German chemist and merchant who was born in Dahme/Marke. He studied chemistry in Dresden, Halle, Leipzig and Berlin.

In 1826 at the age of 20, Unverdorben discovered aniline, which he obtained from the distillation of natural vegetable indigo. He called his discovery Crystallin. Aniline is important in the manufacture of dyes, plastics, and pharmaceuticals. In 1829 he returned to his hometown of Dahme/Mark and became successful in the cigar industry.
