Franz Ziehl

Dr. Franz Ziehl (13 April 1857 in Wismar - 7 April 1926) was a German bacteriologist. He was a professor in Lübeck.

Franz Ziehl introduced the carbol fuchsin stain for the tubercle bacillus in 1882. With pathologist Friedrich Neelsen (1854-1898), he developed the Ziehl-Neelsen stain, also known as the acid-fast stain, which is used to identify acid-fast bacteria.
