ARRI was founded a century ago by two aspiring cinematographers who appreciated the value of technology in the pursuit of their dreams. The excellent adventure of August Arnold and Robert Richter reads like a good screenplay. There is a dramatic arc, with competition, conflict, struggle against odds, stumbles, success and celebration. Serendipity helped, along with good business sense. They were involved in all fields of film production—from manufacturing cameras, lights, and lenses to managing post and rentals.
