Jakob Michael Reinhold Lenz was a Baltic German writer of the Sturm und Drang movement.

Sturm und Drang was a proto-Romantic movement in German literature and music that occurred between the late 1760s and early 1780s. Within the movement, individual subjectivity and, in particular, extremes of emotion were given free expression in reaction to the perceived constraints of rationalism imposed by the Enlightenment and associated aesthetic movements. The period is named after Friedrich Maximilian Klinger's play of the same name, which was first performed by Abel Seyler's famed theatrical company in 1777.
