Lenz is a novella fragment written by Georg Büchner in Strasbourg in 1836.
Jakob Michael Reinhold Lenz, a friend of Goethe, is the subject of the story.
Although left unfinished at the time of Büchner's death in 1837, it has been seen as a precursor to literary modernism.
The story has been adapted for the stage as Jakob Lenz, a 1978 chamber opera by Wolfgang Rihm.
Alexandre Rockwell wrote, directed, produced and edited a feature-length adaptation of Lenz in 1982.
