Who am I? For people who navigate between different countries and cultures, the question of one's own identity takes on a special significance. In this book, Martin Tamcke addresses the experience of self in cultural foreignness not in an abstract and theoretical manner, but concretely and vividly through the dramatic life path of the "Nestorian" Christian Lazarus Jaure (1888-1978). Sent to Germany for his studies and left to fend for himself at an early age, Lazarus pursued his academic ambitions against numerous obstacles, was sent back to his Persian homeland as a missionary, experienced alienation and humiliation at the hands of Western missionary organizations, and ultimately witnessed the genocide of Christians during World War I; he died as an emigrant in the USA. This biography exemplifies profound human experiences at the boundaries of identity.
