was Robert zund associated with an art movement or style? and if so how did it affect his art?

Answer 1

This is all I can find - sorry.

"Representing the Barbizon School of French landscape artists who depicted an idyllic countryside are Robert Zund and Charles-Francois Daubigny. Zund's Harvest (1859-60) is so lovely, the viewer is inclined to forgive any lack of ugly realities. Daubigny (1817-1878), though not a familiar name today, was quite pivotal during the mid-1800s as a directional beacon for many impressionists, such as Monet and Pissarro, who were inspired by his attempts to render atmospheric light. He was one of the few salon-recognized artists who supported the impressionists."

Also,
"The art of Robert Zünd (1827-1909), a Swiss artist, best captured the moments of Biblical events in an old-style fashion."

And

"The works of Robert Zund (1827-1909) may seem rather parochial by post-post-post modern standards but look again, especially at his large-scale “Eichenwald – Foret de Chenes”. It's a forest glade on a summer afternoon. Trees. Lots of trees. Ferns, grass, plants. All executed in a stunning photo-realist style before there were even cameras invented capable of creating such an image. By golly, you can hear the birds singing and the undergrowth rustling."
