Theodor Curtius (1857-1928) was born in Duisberg, Germany, and received his doctorate at the University of Leipzig working with Herman Kolbe. He was professor at the universities of Kiel, Bonn, and Heidelberg (1898-1926).

The first aliphatic diazo compound was isolated much later, namely in 1883 by Theodor Curtius (1857-1928). He obtained diazoacetate 1.2 by diazotization of aminoacetate 1.1. Diazoacetate was the first diazoalkane (Scheme 1-1). 

Acyl azide method, one of the oldest coupling methods in peptide synthesis, introduced by Theodor Curtius in 1902. Starting compounds are amino acid or peptide hydrazides (R-CO-NH-NH2), easily accessible from the corresponding esters by hydrazinolysis, which are transformed into azides (R-CO-N3) by N-... 

We chemists talk in our own special language. . . [I]n the final analysis we think in definite ideas [in bestimmten Vorstellungen], according to which we tell beforehand the course of the phenomena to be examined or confirmed by experiment. If we want to make ourselves understood, it is necessary that such associations of ideas [Ideenassociationen] be self-evident for both speaker and listener, theodor curtius ... 

After this introduction it would seem that no defined peptide bond had been produced prior to Fischers preparative work. However, he did not mention the experiments of Theodor Curtius (1857-1928) published from 1881 and 1882, who—unintentionally at first—had obtained and cleanly characterized benzoyl-glycylglycine (and higher homologs) by the interaction of benzoylchloride and the silver salt of hippuric acid (benzoylglycine). Fischer reported rather exactly on Curtius contributions to the development of peptide chemistry in his great... 

Curtius, T. Ber. 1890, 23, 3033-3041. Theodor Curtins (1857-1928) was bom in Duisburg, Germany. He studied music before switching to chemistry under Bunsen, Kolbe, and von Baeyer before succeeding Victor Meyer as a Professor of Chemistry at Heidelberg. He discovered diazoacetic ester, hydrazine, pyrazoline derivatives, and many nitrogen-heterocycles. Curtius also sang in concerts and composed music. 

Duisberg worked under the guidance of Baeyer s assistant Hans von Pechmann. There he met Theodor Curtius, who later became his good friend.Duisberg was very impressed by the methods of work at the Baeyer institute, which differed markedly from those at the Geuther institute in Jena. ° Together Pechmann and Duisberg studied the reaction of phenoles with acetic acid ethers. 

Theodor Curtius (Duisburg, 27 May 1857-Heidelberg, 8 February 1928) was a pupil of Kolbe. He was professor in Kiel (1889), Bonn (1897) and Heidelberg (1898). He was, like Kolbe, a careful experimenter and with his pupils carried out a large amount of work of outstanding importance. He was an editor of the Journal fur praktische Chemie which has always had a reputation for independence.
