William Chapple (1718–1781) was an English surveyor and mathematician. His mathematical discoveries were mostly in plane geometry and include: * the first proof of the existence of the orthocentre of a triangle, * a formula for the distance between the incentre and circumcentre of a triangle, * the discovery of Poncelet's porism on triangles with a common incircle and circumcircle. He was also one of the earliest mathematicians to calculate the values of annuities.
