Christina is an East Berliner who was born in the GDR, a socialist republic that no longer exists. She danced on the Wall in 1989, and closely observed the restructuring of Germany and the frantic urban transformation of Berlin. At the European University Viadrina in Frankfurt (Oder) she earned an MA in cultural history and comparative social sciences, particularly the ideology-based history of the twentieth century. Her dissertation was on a more contemporary subject of "The Economic Impact of the Contemporary Art Scene on the city of Berlin." She now works as an arts administrator, manages urban development initiatives, and since 2006 routinely walks guests through the eclectic and varied political, cultural, and architectural histories of the German capital and beyond.

Robert grew up in East Berlin during the 1980s and went on to study at the University of Florence, Italy. He received his PhD in cultural studies from Humboldt University of Berlin where his dissertation focused on sexual violence in the Nazi concentration camps. He recently worked as a researcher for the BBC and as a historian for the Sachsenhausen and Ravensbrück concentration camp memorials. His interests range from the history of art and architecture to modern European history and WWII. Robert worked for Hampshire College and has given guest lectures at both Boston University and Brown University. He has been working as a tour guide for more than ten years.

An architect and urbanist, Lucia has been working with Context since 2012. The emphasis of her walks lies in present Berlin from where she leads an exploration into the layers of the past in order to understand the transformations of the city and the significance of its sites, so as to anticipate possible future scenarios. Her thematic focus is on post-war history, urbanism and architectural heritage, as well as on everyday life in Berlin.  Parallel to her work with Context, she has been collecting experiences from different branches: collaborating with several public institutions analysing and comparing the urban landscape of various European cities, developing city guides and organising workshops; working for a design agency specialised in real estate and signage design; and currently, planning housing and office buildings in Berlin with a private project developer. She is a proud ambassador of Berlin and Context.
