Heinrich Ernst Ziegler

from Wikipedia, the free encyclopedia

Heinrich Ernst Ziegler (born July 15, 1858 in Freiburg im Breisgau ; † June 1, 1925 in Ludwigsburg ) was Ernst Haeckel's employee at the University of Jena and, since 1909, professor of zoology at the Agricultural University in Hohenheim . Ziegler dealt with developmental history , genetics and behavioral research and animal psychology .

Ziegler was also a Darwinist on socio-political issues . He was close to the National Liberal Party and criticized the policies of the Social Democrats. In 1900, together with Ernst Haeckel, he initiated a competition by Alfred Krupp on the subject of “What do we learn from the descent theory in relation to the internal political development and legislation of the states?” With the aim of racial hygiene. The jury, to which Ziegler belonged, awarded the prize of 30,000 Reichsmarks to the doctor Wilhelm Schallmayer for his book Heredity and selection in the life of the peoples . In this book, Schallmayer criticized public health care for its negative effects on eugenics and spoke explicitly of the “selective effect of child mortality”.
