Adolf Ferdinand Weinhold (19 May 1841 – 1 July 1917) was a German chemist, physician and inventor.

Life
From 1857 to 1861 Weinhold studied chemistry and physics at universities in Göttingen and in Leipzig. His mentors were Otto Linné Erdmann and Friedrich Wöhler. In Germany, Weinhold worked after university studies as chemist and physician. He was appointed professor at Chemnitz University of Technology in 1870. In 1873 he was granted a D.
