The Weimar Princely Free Drawing School (German: Fürstliche freie Zeichenschule Weimar) was an art and literature educational establishment. It was set up in 1776 in Weimar by the scholar and ducal private-secretary Friedrich Justin Bertuch (1747–1822) and the painter Georg Melchior Kraus (1737–1806), as part of Weimar Classicism. It was financed by the young Charles Augustus, Grand Duke of Saxe-Weimar-Eisenach and heavily promoted by Goethe, who also taught there. Among its pupils were Charles Augustus's future mistress Karoline Jagemann. It lasted until 1930.
As Weimar's Geheimer Rat had oversight over the school from 1788 to 1832, it is not to be confused with the Großherzoglich-Sächsischen Kunstschule Weimar (set up in 1860), the original version of the Weimarer Kunsthochschule. The school's classrooms were originally housed in the Roten Schloss, moving into the Fürstenhaus in 1807 and later moving partly to the Esplanade and partly to the Großen Jägerhaus. From 1824/25, under the oversight of custodian and painter Louise Seidler (1786–1866), it also housed the grand-ducal art collection.
The foundation of the school is a clear indication of the rising interest in arts and crafts in court circles in the second half of 18th century. Its immediate main aim was to instruct local craftsmen in drawing, to sharpen their sense of aesthetics in consumables and in the longer term to increase the quality of production in handcrafts. In order to disseminate art, taste and a sense of beauty to as wide a public as possible, the lessons and living quarters were open to all classes and both sexes. It was an important place for the discovery and promotion of new talent and drew many artists into the orbit of Weimar Classicism and its "Musenhof".
