In 1988, during an assignment for a radio station, Andreas Heinecke was asked to develop a rehabilitation program for a blind colleague. Challenged by this encounter to think beyond his own stereotype prejudice about disability, he created an experience called “Dialogue in the Dark”. Experimenting with sounds and ropes, he presented this idea as an exhibition in Frankfurt, Germany in 1989. Dialogue in the Dark has since evolved into a social business model with exhibitions across 32 countries and 130 cities throughout the world. In the last 25 years more than 8 million visitors have experienced Dialogue in the Dark and thousands of blind guides and facilitators have found employment through Dialogue in the Dark.
