Life[change | change source]
He became a schoolmaster in Liverpool and later a bookkeeper in London. His wide knowledge of mathematics and astronomy attracted Flamsteed's attention. Sharp was invited, in 1688, to enter the Royal Observatory. There he improved instruments and worked as a calculator. He published Geometry Improved and logarithm tables.
He returned to Bradford in 1694. The Atlas Coelestis was the largest star map of its time. It had 26 maps of the major constellations visible from Greenwich, and two planispheres designed by Sharp.
