What makes a city "sustainable" and what can we do to sustain urban forms of life in the 21st century? CoAS experts in politics, philosophy, history, environmental engineering and climate change will weigh in on these urgent questions.

Käthe Kollwitz (1867-1945) was a painter, printmaker and sculptor, and is one of Germany’s most revered artists. Kollwitz’s work illustrates the poverty, war and social injustices of the time. Regarded as a “rebel” because of her work and political beliefs, she was threatened by the Gestapo in 1936. Kollwitz was a passionate artist and remains a controversial political figure. Her work is an enduring testament to her sense of duty as an artist.
