“The Unknown Lincoln” is the only biographical work of the famous writer and teacher Dale Carnegie, published in 1932. The book is dedicated to the personal life of one of the greatest US presidents, Abraham Lincoln, and against the backdrop of modern ideas about the unshakable greatness of the United States and the heroic President Lincoln, who smashed the slave system to smithereens, it is simply revolutionary, since it reveals all the nuances of American history, despite the images polished by propaganda. And Lincoln’s life and career are a complete exception to generally accepted norms, and one can only be surprised at how a simple and naive boy from the very depths of the wild forests, without even a basic education, became the president of a union that was cracking at the seams and in a short period of his reign was able to lay the foundations for the future great power. It seems even more incredible that his main principles both in life and in politics were honesty, mercy and complete renunciation of personal ambitions for the good of society and the country. I really want all modern politicians to read this book at least once...First edition in Russian.
