Most Americans have a general knowledge of the Presidents who have led this country, perhaps not everyone of the 46 Presidents, but the most famous or controversial. Our first President, George Washington, is recognized as the “Father of our Country”; Abraham Lincoln is remembered as the “Great Unifier” during the Civil War; Franklin Roosevelt led our country through the Great Depression and World War II; John F. Kennedy, as the youthful President of a new generation, was assassinated in Dallas; and Barack Obama, our nation’s first African-American President, opened the doors for other leaders of color. These Presidents join other noteworthy Chief Executives like Thomas Jefferson, Teddy Roosevelt, Dwight Eisenhower, Lyndon Johnson, Ronald Reagan and Bill Clinton who were responsible for creating a sense of national purpose and hope, responding to pressing social and economic issues, protecting the country during times of national emergencies and developing public policies that have had a lasting impact on the direction of the country.
