Born on 15 February 1571, Creuzburg an der Werra, Michael Praetorius died in Wolfenbüttel on his 50th birthday, 15 February 1621.
According to Wikipedia, he was born Michael Schultze, the youngest son of a Lutheran pastor, in Creuzburg, in present-day Thuringia. The CyberHymnal says his real name was Michael Schultheiß (German for ‘mayor’, which in Latin is ‘Praetorius’).
Wikipedia adds: “His family name in German appears in various forms including Schultze, Schulte, Schultheiss, Schulz and Schulteis. Praetorius was the conventional Latinized form of this family name.”
The Dances from Terpsichore, a compendium of over 300 instrumental dances, is his most widely-known work – and, regrettably, his sole surviving secular work. His harmonization of Es ist ein Ros entsprungen (Lo, How a Rose E’er Blooming) – written by Praetorius in 1609 – is a particular favourite.
