Signature

Bartolomeu Lourenço de Gusmão (December 1685 – 18 November 1724) was a Catholic priest and naturalist born in colonial Brazil, who was a pioneer of lighter-than-air aerostat design, being among the first scholars at that time to understand the operational principles of the hot air balloon and to build a functional prototype of such a device. He is also one of the main characters in Nobel Prize-winning José Saramago's Baltasar and Blimunda.
