Daredevil was the alias of Matt Murdock, a blind lawyer from New York that moonlights as a vigilante crimefighter. Unlike Batman, he lives and operates on a modest salary with a minimal amount of weapons and gadgets.

Background Information and Notes
Daredevil had a ninja training backstory before Batman, which has now become a near constant in newer incarnations of the character. DC took notice of Frank Miller's work on Daredevil and allowed him to create the influential 1986 Dark Knight comic series.

Batman editor Denny O'Neil also edited Daredevil at Marvel for a time, and invited Miller and Daredevil artist David Mazzucchelli to create the Batman: Year One to revitalize the mainstream continuity.

Trivia

 * Ben Affleck signed on to play the character in the 2003 movie because he is a fan Frank Miller's work, particularly Dark Knight Returns. Michael Keaton's fight double Dave Lea trained Affleck for the role and Jose Fernandez built the costume.
