The German educator Gunild Keetman (5 June 1904, Elberfeld – 14 December 1990, Breitbrunn) was the primary originator of the approach to teaching music known as Orff Schulwerk. Keetman was responsible for most of the actual teaching that was done in the early stages of the movement, perhaps most prominently as the teacher for the radio and television broadcasts that popularized the Schulwerk throughout Germany in the 1950s.
