Benito Pablo Juárez García (March 21, 1806 – July 18, 1872) was a ZapotecAmerindian who served five terms as president of Mexico: 1858–1861 as interim, 1861–1865, 1865–1867, 1867–1871 and 1871–1872. Benito Juárez was the first Mexican leader who did not have a military background, and also the first full-blooded indigenous national ever to serve as President of Mexico and to lead a country in the Western Hemisphere. For resisting the French occupation, overthrowing the Empire, and restoring the Republic, as well as for his liberal efforts to modernize the country, Juárez is often regarded as one of Mexico’s greatest and most beloved leaders. Several towns, schools, parks, streets and monuments have been named to honor and remember him.
Burrhus Frederic Skinner (March 20, 1904 – August 18, 1990) was an American psychologist, author, inventor, advocate for social reform and poet. He was the Edgar Pierce Professor of Psychology at Harvard University from 1958 until his retirement in 1974. He invented the operant conditioning chamber, innovated his own philosophy of science called Radical Behaviorism, and founded his own school of experimental research psychology—the experimental analysis of behavior. His analysis of human behavior culminated in his work Verbal Behavior, which has recently seen enormous increase in interest experimentally and in applied setting. In a recent survey, Skinner was listed as the most influential psychologist of the 20th century. He was a prolific author who published 21 books and 180 articles.
Stephen Grover Cleveland (March 18, 1837 – June 24, 1908) was both the 22nd and 24th President of the United States. Cleveland is the only President to serve two non-consecutive terms (1885–1889 and 1893–1897) and therefore is the only individual to be counted twice in the numbering of the presidents. He was the winner of the popular vote for President three times—in 1884, 1888, and 1892—and was the only Democrat elected to the Presidency in the era of Republican political domination that lasted from 1860 to 1912. Cleveland’s admirers praise him for his honesty, independence, integrity, and commitment to the principles of classical liberalism. As a leader of the Bourbon Democrats, he opposed imperialism, taxes, subsidies and inflationary policies, but as a reformer he also worked against corruption, patronage, and bossism.
He is most remembered for delivering the majority opinion in Dred Scott v. Sandford (1857), that ruled, among other things, that African Americans, having been considered inferior at the time the Constitution was drafted, were not part of the original community of citizens and could not be considered citizens of the United States.
