Johann Kuhnau was a German polymath, known primarily as a composer today. He was also active as a novelist, translator, lawyer, and music theorist, and was able to combine these activities with his duties in his official post as Thomaskantor in Leipzig, which he occupied for 21 years. Much of his music, including operas, masses, and other large-scale vocal works, is lost. His reputation today rests on his Biblical Sonatas, a set of programmatic keyboard sonatas published in 1700, in which each sonata depicted in detail a particular story from the Bible. After his death, Kuhnau was succeeded as Thomaskantor by Johann Sebastian Bach.

Thomaskantor is the common name for the musical director of the Thomanerchor, now an internationally known boys' choir founded in Leipzig in 1212. The official historic title of the Thomaskantor in Latin, Cantor et Director Musices, describes the two functions of cantor and director. As the cantor, he prepared the choir for service in four Lutheran churches, Thomaskirche, Nikolaikirche, Neue Kirche and Peterskirche. As director, he organized music for city functions such as town council elections and homages. Functions related to the university took place at the Paulinerkirche. Johann Sebastian Bach was the most famous Thomaskantor, from 1723 to 1750.
