Abraham Lincoln (February 12, 1809 – April 15, 1865) was an American statesman and lawyer who served as the 16th president of the United States from 1861 until his assassination in April 1865. Lincoln led the nation through the American Civil War, its bloodiest war and its greatest moral, constitutional, and political crisis. He preserved the Union, abolished slavery, strengthened the federal government, and modernized the U.S. economy. Born in Kentucky, Lincoln grew up on the frontier in a poor family. Self-educated, he became a lawyer, Whig Party leader, Illinois state legislator and Congressman. In 1849, he left government to resume his law practice, but angered by the success of Democrats in opening the prairie lands to slavery, reentered politics in 1854. He became a leader in the new Republican Party and gained national attention in 1858 for debating national Democratic leader Stephen A. Douglas in the 1858 Illinois Senate campaign. He then ran for President in 1860, sweeping the North and winning. Southern pro-slavery elements took his win as proof that the North was rejecting the constitutional rights of Southern states to practice slavery. They began the process of seceding from the union. To secure its independence, the new Confederate States of America fired on Fort Sumter, one of the few U.S. forts in the South. Lincoln called up volunteers and militia to suppress the rebellion and restore the Union. As the leader of the moderate faction of the Republican Party, Lincoln confronted Radical Republicans, who demanded harsher treatment of the South; War Democrats, who rallied a large faction of former opponents into his camp; anti-war Democrats (called Copperheads), who despised him; and irreconcilable secessionists, who plotted his assassination. Lincoln fought the factions by pitting them against each other, by carefully distributing political patronage, and by appealing to the American people. His Gettysburg Address became an iconic call for nationalism, republicanism, equal rights, liberty, and democracy. He suspended habeas corpus, and he averted British intervention by defusing the Trent Affair. Lincoln closely supervised the war effort, including the selection of generals and the naval blockade that shut down the South's trade. As the war progressed, he maneuvered to end slavery, issuing the Emancipation Proclamation of 1863; ordering the Army to protect escaped slaves, encouraging border states to outlaw slavery, and pushing through Congress the Thirteenth Amendment to the United States Constitution, which outlawed slavery across the country. Lincoln managed his own re-election campaign. He sought to reconcile his damaged nation by avoiding retribution against the secessionists. A few days after the Battle of Appomattox Court House, he was shot by John Wilkes Booth, an actor and Confederate sympathizer, on April 14, 1865, and died the following day. Abraham Lincoln is remembered as the United States' martyr hero. He is consistently ranked both by scholars and the public as among the greatest U.S. presidents. - 3Dec. at 84 (1706-1790)5,980 votes

Benjamin Franklin (January 17, 1706 [O.S. January 6, 1705] – April 17, 1790) was an American polymath and one of the Founding Fathers of the United States. Franklin was a leading author, printer, political theorist, politician, Freemason, postmaster, scientist, inventor, humorist, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among other inventions. He founded many civic organizations, including the Library Company, Philadelphia's first fire department and the University of Pennsylvania.Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity, initially as an author and spokesman in London for several colonies. As the first United States Ambassador to France, he exemplified the emerging American nation. Franklin was foundational in defining the American ethos as a marriage of the practical values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment. In the words of historian Henry Steele Commager, "In a Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat." To Walter Isaacson, this makes Franklin "the most accomplished American of his age and the most influential in inventing the type of society America would become."Franklin became a successful newspaper editor and printer in Philadelphia, the leading city in the colonies, publishing the Pennsylvania Gazette at the age of 23. He became wealthy publishing this and Poor Richard's Almanack, which he authored under the pseudonym "Richard Saunders". After 1767, he was associated with the Pennsylvania Chronicle, a newspaper that was known for its revolutionary sentiments and criticisms of British policies. He pioneered and was first president of Academy and College of Philadelphia which opened in 1751 and later became the University of Pennsylvania. He organized and was the first secretary of the American Philosophical Society and was elected president in 1769. Franklin became a national hero in America as an agent for several colonies when he spearheaded an effort in London to have the Parliament of Great Britain repeal the unpopular Stamp Act. An accomplished diplomat, he was widely admired among the French as American minister to Paris and was a major figure in the development of positive Franco-American relations. His efforts proved vital for the American Revolution in securing shipments of crucial munitions from France. He was promoted to deputy postmaster-general for the British colonies in 1753, having been Philadelphia postmaster for many years, and this enabled him to set up the first national communications network. During the revolution, he became the first United States Postmaster General. He was active in community affairs and colonial and state politics, as well as national and international affairs. From 1785 to 1788, he served as governor of Pennsylvania. He initially owned and dealt in slaves but, by the 1750s, he argued against slavery from an economic perspective and became one of the most prominent abolitionists. His colorful life and legacy of scientific and political achievement, and his status as one of America's most influential Founding Fathers, have seen Franklin honored more than two centuries after his death on coinage and the $100 bill, warships, and the names of many towns, counties, educational institutions, and corporations, as well as countless cultural references. - 4Dec. at 60 (1858-1919)4,730 votes

Theodore Roosevelt Jr. ( ROH-zə-velt; October 27, 1858 – January 6, 1919) was an American statesman, politician, conservationist, naturalist, and writer who served as the 26th president of the United States from 1901 to 1909. He served as the 25th vice president from March to September 1901 and as the 33rd governor of New York from 1899 to 1900. As a leader of the Republican Party, he became a driving force for the Progressive Era in the United States in the early 20th century. His face is depicted on Mount Rushmore alongside George Washington, Thomas Jefferson, and Abraham Lincoln. He is generally ranked in polls of historians and political scientists as one of the five best presidents.Roosevelt was born a sickly child with debilitating asthma, but he overcame his health problems by embracing a strenuous lifestyle. He integrated his exuberant personality, vast range of interests, and world-famous achievements into a "cowboy" persona defined by robust masculinity. He was home-schooled, and he began a lifelong naturalist avocation before attending Harvard College. His book The Naval War of 1812 (1882) established his reputation as a learned historian and as a popular writer. Upon entering politics, he became the leader of the reform faction of Republicans in New York's state legislature. His wife and his mother both died in rapid succession, and he escaped to a cattle ranch in the Dakotas. He served as Assistant Secretary of the Navy under President William McKinley, but he resigned from that post to lead the Rough Riders during the Spanish–American War, returning a war hero. He was elected Governor of New York in 1898. Vice President Garret Hobart died, and the New York state party leadership convinced McKinley to accept Roosevelt as his running mate in the 1900 election. Roosevelt campaigned vigorously, and the McKinley-Roosevelt ticket won a landslide victory based on a platform of peace, prosperity, and conservation. Roosevelt took office as vice president in March 1901 and assumed the presidency at age 42 following McKinley's assassination the following September. He remains the youngest person to become President of the United States. Roosevelt was a leader of the Progressive movement, and he championed his "Square Deal" domestic policies, promising the average citizen fairness, breaking of trusts, regulation of railroads, and pure food and drugs. He made conservation a top priority and established many new national parks, forests, and monuments intended to preserve the nation's natural resources. In foreign policy, he focused on Central America where he began construction of the Panama Canal. He expanded the Navy and sent the Great White Fleet on a world tour to project the United States' naval power around the globe. His successful efforts to broker the end of the Russo-Japanese War won him the 1906 Nobel Peace Prize. He avoided controversial tariff and money issues. He was elected to a full term in 1904 and continued to promote progressive policies, many of which were passed in Congress. He groomed his close friend William Howard Taft, and Taft won the 1908 presidential election to succeed him. Roosevelt grew frustrated with Taft's conservatism and belatedly tried to win the 1912 Republican nomination. He failed, walked out, and founded the so-called "Bull Moose" Party which called for wide-ranging progressive reforms. He ran in the 1912 election and the split allowed the Democratic nominee Woodrow Wilson to win the election. Following the defeat, Roosevelt led a two-year expedition to the Amazon basin where he nearly died of tropical disease. During World War I, he criticized President Wilson for keeping the country out of the war with Germany, and his offer to lead volunteers to France was rejected. He considered running for president again in 1920, but his health continued to deteriorate and he died in 1919. - 5Dec. at 83 (1743-1826)5,996 votes

Thomas Jefferson was an American Founding Father, the principal author of the Declaration of Independence, and the third President of the United States. He was a spokesman for democracy, and embraced the principles of republicanism and the rights of the individual with worldwide influence. At the beginning of the American Revolution, he served in the Continental Congress, representing Virginia, and then served as a wartime Governor of Virginia. In May 1785, he became the United States Minister to France and later the first United States Secretary of State serving under President George Washington. In opposition to Alexander Hamilton's Federalism, Jefferson and his close friend, James Madison, organized the Democratic-Republican Party, and later resigned from Washington's cabinet. Elected Vice President in 1796 in the administration of John Adams, Jefferson opposed Adams, and with Madison secretly wrote the Kentucky and Virginia Resolutions, which attempted to nullify the Alien and Sedition Acts. - 6Dec. at 76 (1879-1955)953 votes

Albert Einstein ( EYEN-styne; German: [ˈalbɛɐ̯t ˈʔaɪnʃtaɪn] (listen); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). His work is also known for its influence on the philosophy of science. He is best known to the general public for his mass–energy equivalence formula E = m c 2 {\displaystyle E=mc^{2}} , which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led him to develop his special theory of relativity during his time at the Swiss Patent Office in Bern (1902–1909). However, he realized that the principle of relativity could also be extended to gravitational fields, and he published a paper on general relativity in 1916 with his theory of gravitation. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, he applied the general theory of relativity to model the structure of the universe.Except for one year in Prague, Einstein lived in Switzerland between 1895 and 1914, during which time he renounced his German citizenship in 1896, then received his academic diploma from the Swiss federal polytechnic school (later the Eidgenössische Technische Hochschule, ETH) in Zürich in 1900. After being stateless for more than five years, he acquired Swiss citizenship in 1901, which he kept for the rest of his life. In 1905, he was awarded a PhD by the University of Zurich. The same year, he published four groundbreaking papers during his renowned annus mirabilis (miracle year) which brought him to the notice of the academic world at the age of 26. Einstein taught theoretical physics at Zurich between 1912 and 1914, before he left for Berlin, where he was elected to the Prussian Academy of Sciences. In 1933, while Einstein was visiting the United States, Adolf Hitler came to power. Because of his Jewish background, Einstein did not return to Germany. He settled in the United States and became an American citizen in 1940. On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting him to the potential development of "extremely powerful bombs of a new type" and recommending that the US begin similar research. This eventually led to the Manhattan Project. Einstein supported the Allies, but he generally denounced the idea of using nuclear fission as a weapon. He signed the Russell–Einstein Manifesto with British philosopher Bertrand Russell, which highlighted the danger of nuclear weapons. He was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955. Einstein published more than 300 scientific papers and more than 150 non-scientific works. His intellectual achievements and originality have made the word "Einstein" synonymous with "genius". Eugene Wigner wrote of Einstein in comparison to his contemporaries that "Einstein's understanding was deeper even than Jancsi von Neumann's. His mind was both more penetrating and more original than von Neumann's. And that is a very remarkable statement."
