The effect of the saddle-splay elastic constant K24 on nematic director-fields is a topic of fundamental interest for the elastic theory of liquid crystals and plays a vital role in device applications where nematic liquid crystals are confined to a curved geometry. The first measurement of K24 came more than sixty years after the pioneering work of Oseen, who made first steps toward the elastic theory of liquid crystals. Today the study of saddle-splay elasticity has become an important topic in liquid crystal physics. In this review we summarize the various methods used to measure K24 in curved geometries and present the detailed theory behind the measurements.
