Christian Caspar Gabriel Kielland (10 November 1871 in KwaZulu-Natal – 18 March 1941 in Oslo) was a Norwegian gynaecologist, known as the inventor of the Kielland forceps. The tool is probably the most common forceps used for rotation deliveries. The sliding mechanism at the articulation can be helpful in asynclitic births (when the fetal head is tilted to the side), since the fetal head is no longer in line with the birth canal.
