Bruce Wayne approaches Henri Ducard for training in Paris, during his early days traveling the world. Ducard, a knowledgeable detective with excellent man hunting skills, imparted much of his knowledge to the young, keen Bruce.
Later in the series, it is revealed that Ducard is largely amoral, working for criminals as often as he does the law. He deduces Batman's secret identity, but keeps it to himself, thinking as he leaves that Batman continues to exist because true criminals realize that he distracts the people from the greater crimes by his public battle against lesser crimes.
Ducard has also worked with the third Robin, Tim Drake, who went to Paris during his training, as Bruce did. Unlike Bruce, however, Robin only encounters him in passing at the end of his training, in Hong Kong.
