Na minha visita a Maastricht descobri numa praça algo peculiar, uma estátua que deitava fogo! Só quando cheguei à minha casinha e fiiz pesquisa na wikipédia é que soube que esta é uma homenagem a Jean-Pierre Minckelers, o inventor da iluminação a gás, natural desta cidade.
Jean-Pierre Minckelers (Maastricht, 1748 - 4 July 1824) was an inventor of illuminating gas. At the age of sixteen, in 1764, he went to the Catholic University of Leuven (French: Louvain), where he studied theology and philosophy at the Collegium Falconis, in which he became professor of natural philosophy in 1772. At this time the question of aerostats and Montgolfier balloons was occupying the mind of scientists, and Louis Engelbert, 6th Duke of Arenberg, a promoter of science and art, engaged a committee to examine into the question of the best gas for balloon purposes.
Minckelers was on this committee, and in 1784, after many experiments, published a work entitled Mémoire sur l'air inflammable tiré de différentes substances, rédigé par M. Minkelers, professeur de philosophie au collège du Faucon, université de Louvain (Louvain, 1784).
In his memoir Minckelers tells us how he made his discovery: from the very beginning of his experiments he had had the idea of enclosing oil in the barrel of a gun and heating it in a forge. Under action of the heat the oil dissolved and gave way to a very light gas, having other advantageous qualities. Having proved that oil gas was the best for balloons, Minckelers used it for many balloons which rose rapidly and travelled great distances in the neighbourhood of Leuven. As we learn from his pupil von Hulstein, who was in his class in 1785, Minckelers at times used this same gas to light his workshop. Moreover, the drift of his memoir proves clearly that in its inventor's eyes the great combustibility of the gas was one of its leading qualities.
