Jutta Gerta Armgard von Ditfurth (born 29 September 1951) is a German sociologist, writer, and radical ecologist politician. Born into the noble house of Ditfurth, members of which had been noble ministeriales invested with hereditary administrative titles and offices in various regions of today's Saxony-Anhalt and Lower Saxony and elsewhere in the Holy Roman Empire, a daughter of the German physician and science journalist Hoimar von Ditfurth and a sister of the historian Christian von Ditfurth, in 1978 she attempted to have her name legally changed to remove the nobiliary particle "von" and to become the plainer Jutta Ditfurth, but was refused the change by the authorities. She is nonetheless known throughout Germany by her adopted non-noble name, which she prefers. Source: Wikipedia (en)
