- John H. Baron
(b ?Kiel, 1643; d Hamburg, May 20, 1721). German organist and writer, son of Jakob Kortkamp. He studied under Weckmann from 1655 until about 1661, and later in the 1660s he served for a short time as organist at the Jakobikirche, Hamburg, under Christoph Bernhard. His main posts – though they were not important ones – were as organist at two other Hamburg churches, the Maria-Magdalena Kloster (1669–1721) and St Gertrud (1676–1721). His only known composition is a jigg. He also arranged for organ a Magnificat secundi toni by Weckmann and wrote the alto and tenor parts of a cantata by Bernhard. His importance lies in his manuscript chronicle of north German music from 1291 to about 1718, written between 1702 and 1718 (it is now in D-Ha). This gives invaluable accounts of north German organs and their sounds, as well as information about the lives and works of organists, clergy and Kantors, notably in the 16th and 17th centuries. The information he gave on the men whom he and his father knew personally, such as Hieronymus and Jacob Praetorius, Weckmann and Bernhard, is particularly important....
