Hermann-Ragnar Eggers (born March 7, 1910 in Bremen ; † February 5, 2003 in Düsseldorf ) was a graduate engineer and dealt with electrical measurement and control technology . Most recently he was chairman of international specialist committees and editor-in-chief of specialist journals.

Family background

Hermann-Ragnar Eggers came from a family of the educated bourgeoisie, whose ancestors were among others companions of Charles the Bold . Also includes Heinrich Krechting (1501-1580), Heinrich Krefting (1562-1611), Johann Smidt (1733-1857) and Marie Eggers-Smidt (1844-1923) to his ancestors. Hermann-Ragnar Eggers was born on March 7, 1910 as the son of the lawyer and notary Wilhelm Hermann Eggers (1867–1947) and his wife Lydia Doris Sophie, born. Dreyer (1879–1917) was born next to two older sisters - Edda and Insea. His early childhood up to the First World War took place in the family within the framework of the well-protected upper middle class. But then in 1914 the father had to call up for military service as a reserve officer and the mother died in distress and depression in the so-called hunger winter of 1917 . The extensive Bremen relatives then continued to take care of the immediate needs of the boy Hermann-Ragnar Eggers, but from now on he had to live very modestly and undemanding compared to his past.

education

Hermann-Ragnar Eggers had attended the Bremen pre-school (elementary school) since 1916, from which he switched to the New Gymnasium (today: Oberschule am Barkhof ) in 1920 , which he left in 1928 with the final examination. He then studied electrical engineering at the Technical University of Darmstadt , where Hermann-Ragnar Eggers was also active in the Chattia student union (11 lengths , first and second batch ). Then there was a change of university to Berlin; in 1933 he was awarded the degree of graduate engineer there .

Profession until the end of the war

In 1933 he was employed by the Allgemeine Elektrizitäts-Gesellschaft (AEG) as a technical employee for research and development of electrical measuring devices. Soon he was entrusted with the management of the relevant laboratory and sent to numerous business trips and meetings. However, these research and development tasks changed with the outbreak of the Second World War , since all efforts were now adapted to the needs of the war. Hermann-Ragnar Eggers was twice appointed to the position of a so-called " special leader " with the rank of lieutenant and was deployed near the front. For his work, which he later regretted, he was awarded the War Merit Cross .

End of the war and reconstruction

He got married in 1933. This wife and the two sons resulting from the marriage were evacuated to East Germany because of the bombing raids on Berlin . In January 1945, Hermann-Ragnar Eggers managed to bring the family back to Berlin just before the Red Army rolled over them and then sent them from there on a special transport to the Wesermarsch near Bremen. He himself was transferred to Thuringia with important technical documents in order to experience the end of the war there and then get back to the family on foot.

From there he moved with the family to his grandfather's house in Bremen , initially to work temporarily under the most primitive conditions. But in the summer of 1946 Hermann-Ragnar Eggers began to build a new factory for AEG for the production of electrical measuring devices in Heiligenhaus near Düsseldorf and to move there with the family.

Although the family was allocated accommodation in a millionaire's villa in Heiligenhaus, the two starvation winters 46/47 and 47/48 had to be overcome and the children had to sleep in air raid beds until 1956.

But after the start of the economic boom in West Germany, Hermann-Ragnar Eggers was able to build on his professional and scientific successes in such a way that the mining administrations and mining authorities only spoke of the "... famous Eggers ..." and soon over 70 patents bore his name. In addition, in 1957 he was one of the founding fathers of the large international exhibition for measurement, control and regulation technology " Interkama " (international congress with exhibition for measurement technology and automation) in Düsseldorf, which then became part of the "Process Automation" trade fair in 2010 the Hanover Fair.

Even the later legendary head of the Enlightenment Headquarters in the Ministry of State Security of the GDR tried - albeit in vain - to work with Hermann-Ragnar Eggers. In contrast, his professional success gradually led not only to a research department under his leadership with 27 employed graduate engineers, but also to extended business trips to Western Europe, the USA and Canada as well as to the former Soviet Union .

Professional crisis and reorientation

After AEG's research and production site in Heiligenhaus was transferred to Hartmann und Braun in 1968 , Hermann-Ragnar Eggers' responsibility changed fundamentally. He was essentially relieved of his responsibility for research and development and was given the task of becoming increasingly active - while continuing to pay his salary - in academic as well as national and international committees for measurement and control technology.

In this reorientation, he was appointed as a long-standing and popular lecturer at the University of Wuppertal , as chairman of the responsible DIN standards committee and in twelve national interest groups in his field of work.

International association leader

At the International Association of Electrical Engineers and the International Standards Committee, he represented the interests of German and global standardization as a spokesman , and was elected International Chairman of the International Standards Committee due to his worldwide scientific reputation . In this capacity he was able to pursue the interests of his duties with business trips to all continents - except Australia - very successfully.

Activities after retirement

After Hermann-Ragnar Eggers had reached the legal age limit of 65 in the spring of 1975, the retiree was responsible for the editorial support and responsible editing of the specialist journals "Archive for technical measuring + metrological practice" and "Measuring and testing" for a long time to come should deal with acute problems at interesting congresses and meetings.

Private

In 1933 Hermann-Ragnar Eggers married the medical assistant (then: office assistant) Anneliese Zimmermann from a respected Prussian family in which numerous men had worked as pastors or forester as ancestors . This 64-year-old marriage resulted in the following descendants:

• Michael Eggers (* 1936), Ministerialdirigent, paratrooper and Colonel d. R.
• Alexander Eggers (1940–2017), head of a building site laboratory, as well as 5 grandchildren, so far 12 great-grandchildren and 1 great-great-granddaughter.
