Charlotte von Stein
It is the general opinion of scholars that the character Charlotte is based on German high society lady Charlotte von Stein (1742-1827), whom in 1774, although seven years his senior and the mother of seven children, Goethe attempts to win her favor.
After arriving in Weimar, he was soon captivated by the charm of lady Charlotte von Stein (1742-1827), the main person behind the character Charlotte; for more than ten years Charlotte von Stein was his constant companion, and by her bright and genial nature and friendship she stimulated his efforts and assuaged his cares. In a January 1775 by Johann Zimmermann on Charlotte von Stein, he comments: 
"You want me to speak to you of Goethe ... One who visited me the other day made me the following account of Goethe: 24 years old, lawyer, good lawyer, connoisseurs and readers of the ancients, especially the Greeks, poets and writers, orthodox, heretics, Poss driver, musician stands, striking, etched in copper pours in plaster, wood cuts in the - in short, he is a great genius, but a terrible human being. A woman of the world who saw him often, told me that Goethe was the most beautiful, the liveliest, the most original, most ardent, impetuous, at once gentle, seductive, short of the most dangerous for a woman's heart man she met in her entire life."

In a 1775 letter from Goethe to Charlotte von Stein: 
"Oh, I was wrong, once I had a lot of playmates, because I know you, I am almost alone."
On Goethe's return from Italy in 1788 the previous intimate relations between them were relaxed, and the poet's connection with the younger Christiane Vulpius (1765-1816) still further estranged them.
