Laboratory mice make us a gift of their lives. For our lives. The mouse was the second living organism after humans whose genome was sequenced completely. As we resemble each other so closely, mice are now our stand-ins at the forefront of research. Every day, in the world’s laboratories, legions of mice are produced and used as an anonymous mass of animal matter. Can this be morally justified – or could it even be an ethic necessity? The knowledge gained for humans is certainly immense and often vital. Heidi & Hans-Jürgen Koch create a monument to these little heroes and return to them their individuality and personality. In their artistic approach their photographs of these ‘human mice’ are imbued with a universal significance. They reflect nothing less but the dignity of living creatures and our respect for them.
