Gunpowder played a significant role in colonial Brazil. This reached a climax in the eighteenth century, when the country's large gold output enticed the greed of many. The French invasion of Rio de Janeiro in 1711 made the city's defense even more pressing to the metropolis. Brigadier Alpoim symbolized this reaction. He was a leading Luso-Brazilian engineer of that century, whose multiple activities set him apart in colonial life. These activities included a pioneer role in teaching the manufacture and use of gunpowder, about which he wrote extensively during the first half of the eighteenth century. His work is thus among the first to treat chemical technology in the colony at such an early age.
