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.
Appearance in other media
Christopher Nolan's Batman Begins merges Henri Ducard with Ra's al Ghul as the film's main antagonist. Ducard pretends to be subservient to a decoy Ra's al Ghul for the first half of the film, until he reveals that he is in fact the real Ra's al Ghul. He is portrayed by Liam Neeson, while his decoy is played by Ken Watanabe. In The Dark Knight Rises, the younger version of Ra's al Ghul is played by Josh Pence.
Liam Neeson reprised his role as Henri Ducard/Ra's al Ghul in 2005 Batman Begins game, in which he plays a role very similar to that in the film.
The Liam Neeson portrayal of Henri Ducard appears in the Robot Chicken episode "Password: Swordfish" voiced by Seth Green. In a segment that parodies Batman Begins, he trains Heimlich to save people who are choking on food.
