Neil MacGregor focuses on the art of Käthe Kollwitz (1867-1945), who expresses the loss and suffering of war, especially after the death of her younger son Peter at the front in 1914. Neil MacGregor argues that she is one of the greatest German artists. Like no other artist of the time, Kollwitz gave voice to the overwhelming sense of personal loss felt by ordinary Germans - the loss of a whole generation, the loss of political stability and of individual dignity.
