Some of my favorites have already been mentioned so I’ll just add one more for the plant photography nerds out there: Karl Blossfeldt.
We can’t forget David Sibley.
“What it’s Like to Be a Bird” is wonderful as are his field guide illustrations.
Beside great classics (my favourite is E. Haeckel) I really like the works of Isabella Kirkland, whose contemporary works blend perfectly the approach of a naturalist and an artist: https://www.isabellakirkland.com/collections
One of my all time favorite nature artists is Andy Goldsworthy. Please check out his work, it’s well worth it. He usually uses only natural materials, mostly outdoors, and often his work is temporary. Photos record his beautiful artwork.
Oh yes, I remember seeing an article on him and his works - so beautiful!
Wow, as an uncultured Mexican I only knew Caspar David Friedrich because of this famous painting of the man on top of a cliff above the clouds. I’m quite surprised to see he has so many paintings about nature, and they are awesome.
I’m not very aware of the existence of many of these artists, but they are truly awesome. I was going to mention Hokusai but I see he has been mentioned already.
Maybe I should keep it classic and stay with Aivazovsky’s (pelagic?) paintings. I personally appreciate them.
I’ve read The Old Man and the Sea and I’m surprised of how accurate are, in fact, the descriptions of nature and the animals and phenomena that occur in the story. There are many elements that I consider quite representative of the Western Atlantic Ocean.
And although Beethoven’s 6th is so famous, I also appreciate it. I believe it expresses properly the feelings I also feel when I’m out in nature.
Oh! And I read some mentions about Kenn Kaufmann. His illustrations are great, as well as his entries in the Audubon Society website. He has inspired me to improve my nature journalling and sketching.
