"Anna von Helmholtz (nee Anna von Mohl; 19 September 1834 - 1 December 1899), was a German salonnière and writer who translated or edited the translations of a number of scientific works. She was the second wife of the physicist, Hermann von Helmholtz. Brought up in a circle in which intelligence and character were equally well developed, she was described as being talented and clever, with wide views and high aspirations." - (en.wikipedia.org 11.02.2020)
