Wnek was an illiterate carpenter, born in 1828, who went on to be a prolific sculptor, artist, and aviation pioneer. All of this with only natural talent. He studied wings of ducks to try to learn how to fly, and ultimately built a glider that allowed him to make a number of short flights.
His fame was great in the towns where he lived because of his flying ability. He died at the age of 41, when one of his flights went wrong.
He left no written records or drawings of his work in aviation. But I’m not sure how much his constitution was, given Leonardo Da Vinci had made a similar type hundreds of years earlier.
