Henriette Johanne Marie Müller, known as Zitronenjette, was a Hamburg original. At the end of the 19th century, she traveled through the streets and bars of Hamburg's harbour and Neustadt districts with a basket full of lemons to make a living selling the fruit. Lemon, lemon, that's how she advertised her wares and was known not only for her unusual appearance, but also for her drinking strength.
