"This should be a very easy letter to write — words should come easily and in short it should be simple for me to tell you how desperately happy I was to open the paper and see the announcement of our engagement, but somehow I can't possibly say all in a letter I should like to. I love you, precious, with all my heart and to know that you love me means my life. How often I have thought about the immeasurable joy that will be ours some day. How lucky our children will be to have a mother like you..."
Perhaps one of the most romantic love letters of all time was written by late U.S. President George H. Bush to his wife, Barbara. In 1942, on the heels of World War II, Bush enlisted in the Navy, and while stationed overseas, wrote letters to both his parents and then-girlfriend, Barbara Pierce of Rye, New York. To this day, only one love letter to Barbara remains from the former president's time overseas, as Barbara reportedly lost the majority of her letters in a move after the pair were married. In the surviving letter, Bush joyfully explains how he envisions the couple's future, and describes how "lucky" their future children will be.

2. Napoleon Bonaparte to Joséphine de Beauharnais

"Since I left you, I have been constantly depressed. My happiness is to be near you. Incessantly I live over in my memory your caresses, your tears, your affectionate solicitude. The charms of the incomparable Joséphine kindle continually a burning and a glowing flame in my heart. When, free from all solicitude, all harassing care, shall I be able to pass all my time with you, having only to love you, and to think only of the happiness of so saying, and of proving it to you?"
While known for his ruthlessness, French emperor Napoleon Bonaparte also possessed a softer side. In letters to his wife, Joséphine, the military leader reveals a vulnerability not found in his autocratic approach to expanding the French empire. And while he later divorced her when she could not have children, Napoleon continued to write to Joséphine for years after their separation. In one particular letter, penned while Napoleon was commanding the French army near Italy a few months after their marriage, he expresses, quite romantically, how much he misses his wife.

"I can't say how every time I ever put my arms around you I felt that I was home," he writes.
Nobel Prize-winning American novelist Ernest Hemingway was a prolific, confident writer, but in his letters to actress Marlene Dietrich, he shows a more vulnerable side. Hemingway wrote Dietrich, his best friend, approximately 30 letters between 1949 to 1959, but as Dietrich's daughter, Maria Riva, explains in a New York Times article, the two were merely close friends.
