Georg Rüppell was Professor of Behavioral Ecology at the Technical University of Braunschweig and has supervised over 300 studies with his working group, many of them on dragonflies. It was the quick-reaction training he got through his teenage sporting activities, he finds, that helped him to be constantly alert to the abrupt flight movements around him. He was the first biologist in the world to take up the field study of bird flight using slow-mo, and subsequently apply his expertise to dragonflies. He met his wife Dagmar Hilfert-Rüppell on a research trip to the dragonflies of Japan.
Dagmar Hilfert-Rüppell has been studying and filming dragonflies for 30 years. She is particularly fond of damselflies, about which she wrote her doctoral thesis. She has developed infinite patience when filming to capture new behaviors in close-up. She is also the inspired driving force behind their numerous trips all around the world.
