How did the modern organic farming movement begin?

Greetings,
Anyone familiar with the origins and early history of the current, modern organic farming movement as it exists in the US? Who started it all, etc..?
Thank you

My mother had a subscription to Organic Gardening. I read them all.

Rachel Carson was a student of his.

there's a pretty good explanation here https://en.wikipedia.org/wiki/History_of_organic_farming

Steiner in Germany in the early part of last century, Rodale in the US and the Soil Association in the UK and the Commonwealth during WW2. There was a big upswing in the use of chemicals to farm between the two wars, which I guess prompted people to start thinking about what was going on and try and preserve the older ways of gardening/farming.

Any one who know how to ferment your own feeds for hog fateners. Thank you

The February/March issue of Rodale's Organic Gardening gives a great timeline. In it, they mention how Rodale was inspired by the book "An Agricultural Testament" by Albert Howard
