The Thomanerchor (English: St. Thomas Choir of Leipzig) is a boys' choir in Leipzig, Germany. The choir was founded in 1212. The choir comprises about 90 boys from 9 to 18 years of age. The members, called Thomaner, reside in a boarding school, the Thomasalumnat and attend the St. Thomas School, Leipzig, a Gymnasium school with a linguistic profile and a focus on musical education. The younger members attend the primary school Grundschule Forum Thomanum or Anna-Magdalena-Bach-Schule. Johann Sebastian Bach served as Thomaskantor, director of the choir and church music in Leipzig, from 1723 to 1750.
