  • He had the great honor of naming 15 of the 88 constellations in the sky.
  • He spent four years (1750-1754) studying the stars of the southern hemisphere from the Cape of Good Hope – the southernmost part of Africa. (259 years later today in 2013; a single deaf sailor – Gerry Hughes, had sailed passed there from Troon, Scotland to around the world!)
