He invented photography before Daguerre. He travelled across the Amazon jungle, found a way to document the songs of birds without audio recording, and reproduced political pamphlets without the aid of a printing press. And yet, he was forgotten by the world for over a century.

“I am certain that printing using sunlight will be possible in the future,” Florence noted on 15th January 1833. The French inventor was in his late twenties. He was sitting at his desk in a picturesque Brazilian fazenda in São Carlos, a small town with a population of several thousand, 96 kilometres north of São Paulo. The summer was in full bloom. It was a time when many Europeans were trying to capture the light of the sun on paper, among them the painter Louis Jacques Daguerre. How come everyone knows Daguerre’s name and almost nobody has heard of Hércules Florence, even though he was the first to harness the sunlight? It was the surrealist artist André Breton who wrote that: “The greatest weakness of contemporary thought seems to lie in the extravagant overstatement of the known versus what is left to know.” Hércules Florence would probably agree.
