Johann Ernst of Saxe-Weimar (German: Johann Ernst von Sachsen-Weimar)[1] (25 December 1696 – 1 August 1715) was a German prince, son by his second marriage of Johann Ernst III, Duke of Saxe-Weimar. Despite his early death he is remembered as a collector and commissioner of music and as a composer, some of whose concertos were arranged for harpsichord or organ by Johann Sebastian Bach, who was court organist in Weimar at the time.[2]
- ^ He is occasionally referred to as Johann Ernst IV (for example, in the Allgemeine Encyclopädie der Wissenschaften und Künste, Leipzig 1842, II./21., p. 260: article by J S Ersch), implying that he succeeded his father as co-ruler of Saxe-Weimar with his half-brother Ernst August I, both under the regency of their uncle Wilhelm Ernst; this is not well-evidenced.
