Department of Mechanical Engineering

Profile: Rudolf Kolster

Rudolf Kolster was a German teacher who came to Helsinki in during the 1860s and is considered the founding father of mechanical engineering in Finland.

Rudolf Kolster (b. 13 March 1837) began his studies right at the time when formal teaching in mechanical engineering was being introduced to German technical schools. Kolster took to the field and began studying in the Hamburg region by becoming an assistant in the engineering firm J. Lohse & Son.

After spending some time in several engineering firms around northern Germany, Kolster was admitted to the rapidly developing Hanover Polytechnic School. The director of the school was Karl Karmarsch, who worked to promote a theorisation within the engineering sciences in the German engineers' association VDI. Karmarsch's school became known as a centre for applied technology and natural sciences. The school's way of thinking suited Kolster well, since he was a talented mathematician.

Endre Lekve, another Hanover student, had been hired to teach engineering in Helsinki and was visiting Germany in 1860 to handle personal affairs. During the visit, Lekve convinced Rudolf Kolster – who had spent time with Scandinavians as a student – to accompany him back to Finland. Helsinki Technical School director Anders Saelan had already heard of Kolster's abilities during his own visit to Germany a year earlier, and thus Kolster was hired as an assistant teacher in the area of mechanical engineering and engineering drawing.

Rudolf Kolster's role in developing technology student culture and engineer culture in Finland is undisputed. With him, a strong foundation of mathematics and natural sciences was built for what would become the culture of mechanical engineering.

In addition to his work as a teacher, Kolster was responsible for the inspection of steam engines and the training of steam engine operators in Finland together with Martin Wetzer.

In his capacity as an engineer, Kolster participated in many industrial development projects in the late 1800s. These included developing machinery at the industrial plants of Finlayson Co. and Serlachius, equipping the Student House in Helsinki with heaters and designing a mechanism for turning the telescope in the new Helsinki Observatory. At the end of the century, Kolster inaugurated a patent office together with his sons in Helsinki.

Kolster was the first of the Polytechnic Institute's teachers to receive a personal professorship. He was a practical engineer, not an administrator: While he did serve as the institute's deputy director during 1880–1883, the totality of his work cannot be contained in an archive of administrative decisions. Kolster was a cultivator of mechanical engineering.

The polytechnic student association commemorated the professor's sixtieth birthday with a stern-faced portrait in 1897. Rudolf Kolster passed away in 1901.

History of mechanical engineering in Finland

The first professors of the Department of Mechanical Engineering

Part 1.9. When the Polytechnic Institute was reformed into the Technical University of Finland, its teachers were granted the title of professor. Meanwhile, new teachers were being recruited to in anticipation of growing demand for education.

Appendix 1.2. The position of professor of mechanical engineering which had remained vacant since 1908 was filled by Hamburg Technicum senior teacher Ernst Tuckermann, Dr.Eng., who was interested in the position and began work in early September 1911.
