Heinrich Brockmann-Jerosch (1914)

Heinrich Brockmann-Jerosch (born May 23, 1879 in Winterthur , † February 16, 1939 in Zurich ; also known by his Polish first name Henryk ) was a Swiss botanist and pioneer of plant sociology . Its botanical author abbreviation is " Brockm.-Jer. ».

Brockmann was the son of the high school teacher Josef Krzymowski from Łask in Poland. He took part in the unsuccessful January uprising of the Poles against Russian oppression and therefore had to flee abroad. He studied mathematics at the Polytechnic in Zurich and then worked as a teacher at the Cantonal Schools in Zug and later in Winterthur . In 1870 he received Swiss citizenship .

He lost his first wife to a typhus epidemic. In 1874 he married Lucie, née Brockmann, who came from the old Frisian Brockmann family and came from Lübeck. Together they had three sons and two daughters.

Heinrich Brockmann was the third oldest son and, like his three siblings, initially had his father's surname and in 1902 took over the name of his mother Lucie Brockmann. His brother, who was the only one of the siblings to keep his father's name, was the agricultural scientist Richard Krzymowski . Brockmann acquired the double name in 1905 when he married Marie Jerosch , a geologist from East Prussia.

After completing school in Winterthur, he gained practical experience in agriculture for a year in Echallens and then studied agricultural science at the ETH Zurich . There he obtained his diploma as engineer agr. In 1902 and was a scientific assistant at the botanical institute with Carl Schroeter from 1901 to 1904 . After studying science, he received his doctorate in 1906. From 1903 to 1933 he taught as a private lecturer at the University of Zurich and was curator of the Rübel Geobotanical Research Institute in Zurich.

Brockmann-Jerosch, who is one of the pioneers of plant sociology, has primarily taken up aspects of applied plant sociology through his work and has made a significant contribution to the fact that this subject has gained great importance in forestry and agriculture, but also in civil engineering. Among other things, he and his wife explored the natural forests of Switzerland. In another work on the Poschiavo he developed the hypothesis that a number of plants in this area survived the Ice Age. He also clarified numerous aspects of the relationship between vegetation and climate, humans and animals.

Brockmann-Jerosch researched the vegetation conditions in almost all European countries during longer stays abroad and was the leader of the then important International Plant Geography Excursions. Brockmann also dealt scientifically with homeland security and folklore topics such as ethnobotany and farmhouse research.

In 1932 he was elected a member of the Leopoldina Scholars' Academy . He was a member of the Zurich Masonic Lodge Modestia cum Libertate .

Brockmann-Jerosch died in a car accident just ten days after the death of his teacher Carl Schroeter.
