Recently, I was making a school resource on the classification of clouds - a handicraft book with sliding and cascading effects and an electric circuit to light a led under a photo of lightning - and I read about Luke Howard, an englishman, who was pharmacist by profession, and a good observer of clouds formation - the father of meteorology. He gave a lecture that impacted on the scientific community of his time, because, for the first time, a classification of clouds was proposed - https://en.wikipedia.org/wiki/Luke_Howard. It was an innovation that influenced painters and poets of his time. And this fact also explains the interest of Constable to paint the clouds in the sky - http://www.museumsyndicate.com/artist.php?artist=67.

 

Howard corresponded with Goethe, who wrote a series of poems in gratitude to him, including the lines:

But Howard gives us with his clear mind

The gain of lessons new to all mankind;

That which no hand can reach, no hand can clasp

He first has gained, first held with mental grasp

 

And Shelley's poem The Cloud
