Erwin Baur

Erwin Baur (16 April 1875, in Ichenheim, Grand Duchy of Baden – 2 December 1933) was a German geneticist and botanist. Baur worked primarily on plant genetics. He was director of the Kaiser Wilhelm Institute for Breeding Research (since 1938 Erwin Baur-Institute). Baur is considered to be the father of plant virology. He discovered the inheritance of plastids.

In 1908 Baur demonstrated a lethal gene in the ''Antirrhinum'' plant. In 1909 working on the chloroplast genes in ''Pelargonium'' (geraniums) he showed that they violated four of Mendel's five laws. Baur stated that #plastids are carriers of hereditary factors which are able to mutate. #in variegated plants, random sorting out of plastids is taking place. #the genetic results indicate a biparental inheritance of plastids by egg cells and sperm cells in pelargonium.

Since the 1930s and the work of Otto Renner, plastid inheritance became a widely accepted genetic theory.

In 1921 and 1932 Baur co-authored with Fritz Lenz and Eugen Fischer two volumes that became the book ''Human Heredity'', which was a major influence on the racial theories of Adolf Hitler. The work served a chief inspiration for biological support in Hitler's "Mein Kampf". Provided by Wikipedia
