Charlotte von Hagn was a famous German actress who performed in Vienna, Dresden, Berlin, Budapest, St Petersburg and Hamburg and was celebrated everywhere she went. Her talent for comedy was apparently based on her beauty and demeanor. She was described as a witty and charming conversationalist.
Had multiple affairs including one with Bavarian King Ludwig I. Charlotte met the king shortly after her 17th birthday, and after a quickie tryst the smitten monarch commissioned a portrait of her from his court painter Joseph Karl Stieler in 1828 for his Gallery of Beauties.
The painting portrays Charlotte as the character of Thekla from Schiller’s poem “Wallensteins Camp,” one of Ludwig’s favorite pieces of literature.

Her other famous affair was with the famous composer and pianist Franz Liszt. Charlotte wrote a love-poem on the corner of a her fan and presented it to Liszt following his first Berlin performance. The poem is a discussion about love between a poet and in inquirer, who poses two questions for the poet to answer.

What is Love?
Poet, what is love? Will you not tell me!
Love is when the soul takes a breath.
Poet, what is a kiss? Do tell me, please!
The shorter it is, the greater the sin!

Liszt could neither resist Charlotte nor the poem; she quickly became his lover and Franz used the poem in three separate song-settings on the same text. Several years later, when Charlotte was married to Baron von Oven, she wrote to Liszt, “You have spoiled all others for me. No one can stand the comparison.” This statement might actually account for the fact that her marriage only lasted 3 years. Liszt, on the other hand, called Charlotte “the concubine of two kings.” Clearly Franz thought of himself as royalty, so that would account for one of the kings. The other being Ludwig I.
