Plessy v. Ferguson

Sweatt v. Painter, 339 U.S. 629 (1950) , was a U.S. Supreme Court case that successfully challenged the "separate but equal" doctrine of racial segregation established by the 1896 case "Plessy v. Ferguson".
 The case was influential in the landmark case of "Brown v. Board of Education" four years later.
Albion Winegar Tourgée (May 2, 1838 – May 21, 1905) was an American soldier, Radical Republican, lawyer, writer, politician, and diplomat.
 A pioneer civil rights activist, he founded the National Citizens' Rights Association, established the historically black women's college Bennett College, and litigated for the plaintiff Homer Plessy in the famous segregation case "Plessy v. Ferguson" (1896).
 Historian Mark Elliott credits Tourgée with introducing the metaphor of "color-blind justice" into legal discourse.
Constitutional colorblindness is an aspect of United States Supreme Court case evaluation that began with Justice Harlan's dissent in "Plessy v. Ferguson "in 1896.
 Prior to this (and for a good while afterwards), the Supreme Court considered color as a determining factor in many landmark cases.
 Constitutional colorblindness holds that skin color or race is virtually never a legitimate ground for legal or political distinctions, and thus, any law that is "color conscious" is presumptively unconstitutional regardless of whether its intent is to subordinate a group, or remedy discrimination.
 The concept, therefore, has been brought to bear both against vestiges of Jim Crow oppression, as well as remedial efforts aimed at overcoming such discrimination, such as affirmative action.
Brown v. Board of Education of Topeka, 347 U.S. 483 (1954) , was a landmark United States Supreme Court case in which the Court declared state laws establishing separate public schools for black and white students to be unconstitutional.
 The decision overturned the "Plessy v. Ferguson" decision of 1896, which allowed state-sponsored segregation, insofar as it applied to public education.
 Handed down on May 17, 1954, the Warren Court's unanimous (9–0) decision stated that "separate educational facilities are inherently unequal."
 As a result, "de jure" racial segregation was ruled a violation of the Equal Protection Clause of the Fourteenth Amendment of the United States Constitution.
 This ruling paved the way for integration and was a major victory of the Civil Rights Movement, and a model for many future impact litigation cases.
 However, the decision's fourteen pages did not spell out any sort of method for ending racial segregation in schools, and the Court's second decision in "Brown II", 349 U.S. 294 (1955) only ordered states to desegregate "with all deliberate speed".
Betts v. Brady, 316 U.S. 455 (1942), was a landmark United States Supreme Court case that denied counsel to indigent defendants when prosecuted by a state.
 It was famously overruled by "Gideon v. Wainwright".
Berea College v. Kentucky, 211 U.S. 45 (1908) was a significant case argued before the United States Supreme Court that upheld the rights of states to prohibit private educational institutions chartered as corporations from admitting both black and white students.
 Like the related "Plessy v. Ferguson" 163 U.S. 537 (1896) case, it was also marked by a strongly worded dissent by John Marshall Harlan.
 The ruling also is a minor landmark on the nature of corporate personhood.
Homer Adolph Plessy (March 17, 1862 – March 1, 1925) was a Louisiana French-speaking Creole plaintiff in the United States Supreme Court decision in "Plessy v. Ferguson".
Roberts v. Boston, 59 Mass. (5 Cush.)
 198 (1850), was a court case seeking to end racial discrimination in Boston public schools.
 The Massachusetts Supreme Judicial Court ruled in favor of Boston, finding no constitutional basis for the suit.
 The case was later cited by the US Supreme Court in "Plessy v. Ferguson", which established the "separate but equal" standard.
John Howard Ferguson (June 10, 1838 – November 12, 1915) was an American lawyer and judge from Louisiana, most famous as the defendant in the "Plessy v. Ferguson" case.
 Ferguson was born the third and last child to Baptist parents (John H. Ferguson & Sarah Davis Luce) on June 10, 1838 in Chilmark, Massachusetts.
 The son, grandson, great-grandson, and great-great-grandson of Martha's Vineyard (Chimark & Tisbury) Master Mariners, John Howard Ferguson chose a different vocational path and taught school in his early years, finally setting about to study law.
 Young Ferguson's family was all but wiped out between 1849–1861, and after the Civil War ended, and he had completed his legal studies in Boston under the tutelage of Benjamin F. Hallett, Ferguson moved to New Orleans in 1865.
 There he met and married in July 1866, Virginia Butler Earhart, daughter of Thomas Jefferson Earhart, a staunch and outspoken abolitionist from Pennsylvania.
 The Fergusons raised three sons (Walter Judson, Milo & Donald Ferguson) in Burtheville (Uptown New Orleans) at 1500 Henry Clay Avenue.
 The house still stands today and is designated a historical landmark of the 1989 Orleans Parish Landmarks Commission.
Plessy v. Ferguson, 163 US 537 (1896) was a landmark constitutional law case of the US Supreme Court decided in 1896.
 It upheld state racial segregation laws for public facilities under the doctrine of "separate but equal".
 The decision was handed down by a vote of 7 to 1 with the majority opinion written by Justice Henry Billings Brown and the dissent written by Justice John Marshall Harlan.
