Ernst-Otto Reher

Ernst-Otto Reher (born April 12, 1936 in Güsten ; † November 18, 2016 in Halle (Saale) ) was a German process engineer and professor . He is one of the pioneers of process engineering teaching and research in the field of technical rheology and general technology .

education

Ernst-Otto Reher was born in Güsten near Bernburg (Saale) . After finishing school he started an apprenticeship as a carpenter. As a working-class child with very good academic achievements, he was delegated to the Workers 'and Farmers' Faculty (ABF) at the University of Halle (Saale) , where he graduated from high school in 1956 and at the same time had prepared himself linguistically for studying abroad, especially for studying in the Soviet Union.

In the years 1956 to 1961 he completed his studies at the traditional “Leningrad Technological Institute” (LTI) in Leningrad , today again St. Petersburg , in the field of “processes and apparatus”, comparable to the German training in process engineering . The LTI is one of the oldest technical universities in Europe, where Dmitri Ivanovich Mendeleev taught in the 19th century . This institution became an alma mater for Ernst-Otto Reher , which shaped him scientifically and to which he maintained scientific and personal connections for a lifetime. Here the thirsty student made friends with fellow students who stayed alive until his death.

After completing his studies in 1961, he started working for the " VVB Lacke und Farben" in Berlin . His urge for active research soon led him back to the university in St. Petersburg, where he worked in the years 1962 to 1965, a postgraduate at PG Romankow began he to the promotion of Doctor of Engineering (Dr.-Ing.) With completed the dissertation "Drying pastes in a fluidized bed dryer".

Here in Leningrad, the marriage bond was established with his wife Svetlana Nikolashenkava in 1960 , with whom he was married until his death. She studied German and English at the University of Leningrad and then worked there as a German teacher. Swetlana Reher came to the GDR with him after studying with Ernst-Otto Reher and worked as a Russian teacher at an academic training and research facility. In 1962 their son Ondré Reher was born, and when he was three months old, he and his parents moved to Leningrad because Ernst-Otto Reher was admitted to the LTI. After graduation in 1965, the family returned to the GDR, both spouses took up a job at the THLM, Swetlana Reher worked there in language editing. Therefore the son Ondre grew up in Halle (Saale) and studied after the Abitur at the Martin Luther University of Halle-Wittenberg , the Department of German Studies . He is now an entrepreneur in Berlin. And there is a grandson Marc Reher who is married, lives in Augsburg and has two children. Swetlana and Ernst-Otto Reher can refer to two great-grandchildren, i.e. three generations of descendants.

From 1965 Reher worked as a senior assistant at the Technical University of Leuna-Merseburg , which is currently being established , at the Institute for Process Engineering in the Mechanical Process Engineering department, headed by Wilhelm Jugel . Reher turned to the processing of plastics, i.e. the non-Hooke and non-Newtonian substances and thus their characterization, rheology and rheometry as well as their production and processing - a new area that was later referred to as processing technology.

In 1971 he received his doctorate B to the Doctor of Science (Dr. sc. Techn.) At the Technological Institute in Leningrad.

In 1972 he was appointed full professor for process engineering (technical rheology) at the TH Leuna-Merseburg. This was followed by 20 years of work in the field of process engineering at the TH Merseburg as a university lecturer, researcher and internationally respected author.

Ernst-Otto Reher assumed management responsibility as director of the “Process Engineering” section, later of the “Materials and Processing Technology” section. He headed the problem laboratory "Technology of Information Recording Materials" and later as director of the Collaborative Research Center "Polymeric Materials". Reher took part in procedural film research and chemical research at the Wolfen film factory (ORWO).

Activity in the free economy

The German reunification in 1990 meant a deep turning point in Reher's professional life, as the TH Merseburg was gradually dissolved as an independent university and only individual parts were connected to the Martin Luther University Halle-Wittenberg . Reher therefore switched to the private sector and ended his activity at the TH Merseburg in 1992.

He became head of research and development at "Göttfert Material-Prüfmaschinen GmbH" in Buchen / Odenwald . This company was founded by Otto Göttfert in 1962 and has developed into one of the leading manufacturers of rheological testing devices for thermoplastics, duromers and rubber. Together with this company, Reher had already set up a “rheological laboratory” at the TH Merseburg after reunification, which was considered to be the best-equipped laboratory of its kind in united Germany. The benefit of this commitment lay on both sides - in addition to the economic successes for the company, it ensured for Reher personally the continuity and topicality of the connection to his field of "process engineering" in a complicated time. He carried out this activity until he retired in 1999.

During this time, the Trothaer Kreis in Halle (Saale) , a union of former colleagues from the TH Merseburg, who primarily focused on maintaining the rich scientific and historical heritage of the Central German region in the field of chemistry and process engineering, was established with the significant contribution of Reher the legacy of Nobel Prize winner Wilhelm Ostwald . The public appearances of the circle also include the installation of a memorial plaque for the Nobel Prize winner Karl Ziegler on the house in which he lived during his work at the university in Halle (Saale). Shared experiences with active academic exchange, combined with cultural highlights and multi-day hikes in the region, welded this specialist group together permanently, thus preventing isolation and isolation.

Reher's scientific work has left its mark both in academia and in industry. These can be found on the one hand in his publications and also in the measuring systems and measuring devices that have been and are being built according to his proposals. On the other hand, traces can be found in his students and employees who have passed through his hands and been shaped by his personality as a university professor. This applies above all to those employees who Reher has led to their doctorate and some of whom are active in important positions in science and business.

Activity in the "General Technology" working group

He received the impetus for this field of work at a young age when, while visiting his alma mater in St. Petersburg, he came across the work of the Göttingen professor Johann Beckmann , who had taught there from 1763 to 1765 and was vehemently required in his work and named the subject of such a future discipline “General Technology”.

Reher made a major contribution to the fact that this subject area “General Technology” was filled step by step with life and scientific substance and that the results were made available to the public - in the meeting reports and papers of the Leibniz Society of Sciences in Berlin and in other media . Reher was also involved in the design of the first seven symposia and the associated publications:

  • 2001: General Technology - Past and Present
  • 2004: Advances in General Technology Formation
  • 2007: General technology - generalized specialist knowledge and concrete orientation knowledge about technology
  • 2010: Ambivalences of Technologies - Opportunities, Dangers, Abuse
  • 2012: Technology - Security - Technical Security
  • 2014: Technological change in the knowledge society - qualitative and quantitative changes
  • 2016: Technology and Sustainable Development.

In series of lectures to students and engineers, Reher, together with Wolfgang Fratzscher , Klaus Krug and Gerhard Banse , represented and disseminated the ideas and concepts of general technology that he had already outlined in 1968: Within the engineering disciplines of process engineering, manufacturing technology and processing technology, generalizations were made within the framework of the technological basic operations or process groups realized. The mechanics and the basics of the impulse, heat and mass transfer, the system technology provided the prerequisites for this. ... The basis for such partial integration of the process techniques of the material transformation was the uniform methodology in the modeling, simulation and optimization of the process elements.

The treatment of problems arising from the complex interactions between scientific-technical, economic, ecological and social requirements for future technology development - outlined with the keywords technical safety , ambivalence and sustainability of future development - gained increasing importance in the last few years . This stretched the framework from technical subject systems to socio-technical to political and ecological systems, an area of ​​activity whose results are primarily aimed at a broad public of technology companions, such as teachers, economists, philosophers, sociologists and politicians.
