Leonard Alfred Schneider, better known by his stage name Lenny Bruce, was an American stand-up comedian, social critic, and satirist. He was renowned for his open, free-wheeling, and critical style of comedy which contained satire, politics, religion, sex, and vulgarity. His 1964 conviction in an obscenity trial was followed by a posthumous pardon in 2003.

An obscenity is any utterance or act that strongly offends the prevalent morality of the time. It is derived from the Latin obscēnus, obscaenus, "boding ill; disgusting; indecent", of uncertain etymology. Generally, the term can be used to indicate strong moral repugnance and outrage in expressions such as "obscene profits" and "the obscenity of war". As a legal term, it usually refers to descriptions and depictions of people engaged in sexual and excretory activity.
