The constellation was invented in the 18th century. At that time, science was flourishing in Europe. Academies and scientific societies were founded – following the English Royal Society in 1660, similar foundations were established throughout Europe. International cooperation was strengthened as scientists exchanged ideas, organised joint observation campaigns such as the measurement of the transits of Venus in 1661 and 1669, and collected data in one place (Paris). Scientists also collaborated in societies across national and linguistic boundaries, so that new discoveries spread rapidly. Experiments laid the foundations for modern thermodynamics.

Among the numerous technical inventions of the time was the vacuum pump. In 1654, Otto von Guericke demonstrated to an impressed audience in Magdeburg the power of air pressure holding two hemispheres together. They had previously been pumped free of air using a vacuum pump.

This invention in turn inspired experiments with steam. The boiling process under high pressure was investigated, leading to the invention of the precursor to the pressure cooker.

Both the vacuum pump for pumping out air and the pump for letting air into submarines or diving helmets may have been inspired by this idea.

The fact is that the constellation was defined by Nicolas Louis de la Caille. Between 1750 and 1754, he worked at the Cape of Good Hope, where he surveyed the land as a geodesist and the sky as an astronomer. In the Mémoires de l'Académie Royale des Sciences, he wrote in 1756 that the device known as the ‘pneumatic machine’ was symbolic of experimental physics.

It is therefore a celestial monument to a subject.
