Geheimrat Julius Wilhelm Theodor Curtius (27 May 1857 – 8 February 1928) was professor of Chemistry at Heidelberg University and elsewhere. He published the Curtius rearrangement in 1890/1894 and also discovered diazoacetic acid, hydrazine and hydrazoic acid.

Theodor Curtius was born in Duisburg in the Ruhr area in Germany. He studied chemistry with Robert Bunsen at Heidelberg University and with Hermann Kolbe at Leipzig University. He received his doctorate in 1882 in Leipzig.

After working from 1884 to 1886 for Adolf von Baeyer at the University of Munich, Curtius became the director of the analytical chemistry department at University of Erlangen until 1889. Then he accepted the chair in Chemistry at the University of Kiel, where he remained very productive. In line with this success, Curtius was appointed Geheimer Regierungsrat (Privy Councillor) in 1895. After a one-year appointment as the successor of the famous August Kekulé at Bonn University in 1897, Curtius succeeded Victor Meyer as Professor of Chemistry at his old university in Heidelberg in 1898, where he remained until his retirement in 1926. He was succeeded by Karl Freudenberg, who wrote Curtius' biography in 1962.
