It was with great sadness that we learnt of the tragic murder of Ross Langdon and his wife Elif Yavuz in the terrorist attacks in Nairobi on Saturday. They were expecting their first baby in a couple of weeks. Ross spoke at TEDxKraków in 2012 about his work as an architect in Africa. He devoted his life to creating sustainable architecture that is integrated into communities, and he left us with hope for humanity. It’s impossible to make sense of this senseless and shocking loss of life. We send our condolences to both their families.
