Johannes Krötenheerdt

Johannes Krötenheerdt (born May 16, 1933 in Thuringia ; † January 18, 2014 ) was a German physicist and university professor .

Life

Krötenheerdt came from an old Thuringian peasant family who lived in the area of Zickra , Clodra and Dittersdorf .

During and after his studies, Krötenheerdt dealt with fluid mechanics and aerodynamics . He was involved in a secret mission in which the GDR tried to develop a type of aircraft. This mission failed and was canceled after two crashes and an engine fire. Investigations into the flow behavior of missiles in the air and torpedoes in the water followed.

In 1961, Krötenheerdt founded the organization and computing center of the Martin Luther University Halle-Wittenberg and became its director. He held this position for more than 30 years. Krötenheerdt was involved in the development, production and programming of the ZRA 1 .

1967 doctorate toads Heerdt at the Martin Luther University of Halle-Wittenberg for Dr. rer. nat. with a thesis on the topic of determining symmetrical profile flows close to sound with two stagnation points using the hodograph method . In 1978, Krötenheerdt completed his habilitation with a thesis on the subject of a contribution to the methodical conceptual realization of interactive computer systems for collective use with application orientation to the teaching process .

In 1986, Krötenheerdt organized an international conference on the subject of the computer as an intelligent work tool at the University of Halle and published the lectures held there as a book.

The West German association Computerhilfe organized an IBM / 38 with two 560 MB disk stations for Krötenheerdt's data center. To achieve this, high bureaucratic, state and political hurdles had to be overcome in early 1990. Through a malicious article in the Spiegel , in which the arrogance of the West towards the East was expressed, almost all efforts of the parties involved would have been ruined at the last moment.

From 1960 to 1991 Krötenheerdt was the editor of the journal Articles on Information Processing from the Organization and Computing Center of the Martin Luther University Halle-Wittenberg .

In 1995, Krötenheerdt was the managing director of a German wind turbine company.

In 2007, Krötenheerdt published a two-volume chronicle about his homeland, the triangle Zickra, Clodra, Dittersdorf.

Krötenheerdt was married and had children, grandchildren and great-grandchildren. He had an older brother, Otto Krötenheerdt (1929-2018), who was also a professor in Halle.
