The trained biologist and granddaughter of the famous zoologist and biologist Ernst Haeckel lived in a house on Schererweg in Murnau from 1969 until her death in 1994. She had originally studied botany, chemistry and geography in Jena and, with the addition of zoology and geology, in Munich. Haeckel initially wanted to follow in her grandfather's footsteps and "[...] work scientifically as a botanist and, if possible, accompany expeditions and process their results." In 1928 she received her doctorate on "Iridaceae" (iridaceae). From 1929 to 1938 she was a research assistant at the universities of Göttingen and Halle. At the same time, she took the first and second state examinations for higher teaching in Bavaria. When the funding for her position at the University of Halle ran out, she applied for a position as a study assistant at the private secondary girls' school of the Murnau school association in 1939. Two years later she was already headmistress, a position she held until her retirement in 1966. In the meantime, the private girls' school had become a state secondary school. Since 1923 she had been a member of the German Alpine Association, in 1939 she joined the Nature Conservation Association and was passionate and very persistent in her efforts to protect the Murnau Moor. It is thanks to her persistence and her communication in countless moor tours and lectures that we have become aware of the need to preserve the moor and understand the landscape around Murnau.
