Heinz Itzerott

Karl Heinz Itzerott (born December 12, 1912 in Müuellen ; died November 12, 1983 in Grünstadt ) was a German scientist .

Life

Heinz Itzerott was the son of the engineer Walter Itzerott and his wife Marie. His father was seriously wounded in fighting near Arras in northern France during World War I in 1915 and died a little later. His mother died in 1918 in a major flu epidemic in Dessau . Heinz Itzerott had been an orphan since he was five and spent childhood and adolescence with Richard Nagel's family of doctors in Rehau . After four years at the local elementary school, he attended the Oberrealschule in Hof until he graduated from high school in 1932.

Heinz Itzerott then studied biology and chemistry at the University of Erlangen and the University of Munich . He received his doctorate magna cum laude in 1936 as Dr. rer. nat. with Julius Schwemmle at the University of Erlangen on investigations into the water balance of Prasiola Crispa . Together with Karl Mägdefrau , Heinz Itzerott held a seminar with lectures and excursions about the German forest at Erlangen University in the winter semester of 1934/35.

On February 26, 1938 he married his former classmate Emmi, geb. Fisherman. The daughter Brigitte was born on December 10, 1940. During the Second World War , Heinz Itzerott was temporarily drafted into the Wehrmacht and made indispensable several times. The family's house on Corneliusstrasse near Gärtnerplatz in Munich was completely destroyed by American bombs on July 13, 1944.

job

After starting his career at the State Institute for Crop Production and Plant Protection in Munich in 1936, Heinz Itzerott became deputy head of the Plant Protection Office of the Bavarian State Farmers' Union. His office was relocated to Boos in the Allgäu during the Second World War . On July 13, 1945, Heinz Itzerott was suspended from duty by the American military government. In the following years he occasionally did auxiliary work in agriculture, e.g. B. in the determination of pests. He also developed a mist nozzle sprayer for use in agriculture and fruit growing, for which he received a German imperial patent.

On April 1, 1949, a new start was made at the crop protection company CFSpiess & Sohn in Kleinkarlbach . Heinz Itzerott built up the biological department there and became its head. In 1968 he became the company's authorized signatory. During his time at Spiess he also received one or more American patents. At the end of 1977 he retired, but remained connected to the company in an advisory capacity. In addition, because of a lack of teachers, he taught biology at the Leininger grammar school in Grünstadt for a few years .

Research on dragonflies and mushrooms - odonatology and mycology

During his free time and after his retirement, Heinz Itzerott initially dealt with large dragonflies (odonates), which he photographed in the respective biotope, but never caught. His slide collections were known and valued by experts and colleagues. He wrote numerous publications, some together with domestic and foreign colleagues, including Gerhard Jurzitza and Alois Bilek . He gave slide shows as part of nature conservation projects and worked on the Red List of Dragonflies in Rhineland-Palatinate . Heinz Itzerott was also involved in the BUND and tried above all to put endangered areas under protection.

After Heinz Itzerott had worked almost completely on the series of dragonflies living in Europe, he conducted research on Ascomycetes , especially the Octospora genus. In this area, too, he wrote numerous publications, mostly with photos and drawings, which appeared at home and abroad. He researched and published together with Richard William George Dennis , mycologist at the Royal Botanic Gardens (Kew) , London, and Roy Kristiansen, editor of the mycological journal AGARICA in Torp , Norway, as well as Peter Döbbeler from the Institute for Systematic Botany in Munich and Josef Poelt from Graz. A new species described by him was named Octospora itzerottii in his honor .

After Heinz Itzerott's death in 1983, the Palatinate Museum for Natural History in Bad Dürkheim took over a large part of its slide collection. Heinz Itzerott's mushroom herbarium is located in the University of Munich. It is mainly Octospora from Rhineland-Palatinate. The herbarium is inventoried under the number 4341.
