Clarence Earl Gideon was a poor drifter accused in a Florida state court of felony breaking and entering. While in prison, he appealed his case to the US Supreme Court, resulting in the landmark 1963 decision Gideon v. Wainwright holding that a criminal defendant who cannot afford to hire a lawyer must be provided one at no cost.

Gideon v. Wainwright, 372 U.S. 335 (1963), was a landmark U.S. Supreme Court decision in which the Court ruled that the Sixth Amendment of the U.S. Constitution requires U.S. states to provide attorneys to criminal defendants who are unable to afford their own. The case extended the right to counsel, which had been found under the Fifth and Sixth Amendments to impose requirements on the federal government, by imposing those requirements upon the states as well.
