Fornax is another one of the constellations invented by by Abbe Nicholas Louis de Lacaille who mapped the stars of the southern hemisphere from the Cape of Good Hope in the years from 1751 to 1753.
De la Caille originally originally named the constellation "Fornax Chemica," the Chemical Furnace. He named the constellation in honor of the famous French chemist Antoine Laurant Lavoisier, one of the most important persons figuring in the birth of modern chemisty. Lavoisier was later to be executed during the French Revolution.
Fornax is an extremely dim constellation. It contains no stars brighter than about fourth magnitude.
