The Dr.-Ing. (acronym for Doktor-Ingenieur or Doktor der Ingenieurwissenschaften) is the German engineering doctorate degree, comparable to the Doctor of Engineering , Engineering Doctorate, Doctor of Science (Engineering), Doctor of Science (Technology) or a PhD in Engineering.
It was first introduced in 1899 at the prussian Institutes of Technology. The other german states adopted it in the following years. In contrast to the other historic doctoral degrees (e.g. Dr. phil., Dr. jur. or Dr. med.), the Doktor-Ingenieur was not named latin but german, and therefore written with dash (Dr.-Ing.).
