Doctor Peter Bradey was the second Invisible Man after having successfully achieved in recreating Hawley Griffin's original experiment from his discovered notebooks.
In the 1940's, Bradey enlisted in the League as an attempt to fill in Griffin's role; however, Bradey was considered to be distinctively second rate as an operative due to his compulsive chain-smoking and coughing fits, which, upon numerous occasions, gave his presence away. Bradey left the League following its short term battle against James Soames and Count Zero.
Peter Brady is from the British TV series The Invisible Man (1958-1960). In the show Peter Brady, a British scientist, is turned invisible in an accident.
