Trying to Get a Summary of Permaculture History

So I know that Permaculture is inspired by indigenous agricultural practices worldwide...that said, it was named and codified in the 1970s by an Australian and his assistant? Or did these two Australians equally "found" or establish it? (I am confused as to David Holmgren's place in the Permaculture movement. He helped write one book, the first book, and then never worked further with Mr. Mollison? But then has subsequently written books on the topic on his own, and writes blurbs for all the Permaculture books published these days?) But another Australian, Geoff Lawton, took on Mr. Mollison's efforts somehow after his death? My understanding of this is very murky.

But also then Sepp Holzer in Austria had nothing whatsoever to do with them, but his sensible farm land-management practices have led him to be considered one of the founders of the permaculture movement, if it can be called a movement? (I have read one of his books.)

And also Masanobu Fukuoka of Japan is related to Permaculture, but he didn't know any of the others either? (I have read two of his books.)

Can someone (with a decent amount of free time this evening, ha ha!) clarify this?

Permaculture (from "permanent agriculture")[3] is an integrated system of ecological and environmental design which Mollison co-developed with David Holmgren, and which they together envisioned as a perennial and sustainable form of agriculture. In 1974, Mollison began his collaboration with Holmgren, and in 1978 they published their book Permaculture One, which introduced this design system to the general public.

Mollison founded The Permaculture Institute in Tasmania, and created the education system to train others under the umbrella of permaculture.

In October 1997 Bill Mollison, upon his retirement, asked Lawton to establish and direct a new Permaculture Research Institute on the 66 hectare Tagari Farm developed by Mollison. Lawton further developed the site over three years and established The Permaculture Research Institute Australia as a not for profit company. PRI was eventually moved to Zaytuna Farm, in The Channon, where it continues today.

I would start with a definition of what permaculture is.  Depending upon how I define it, I can trace it back to the 1800’s.   I am sure that others, depending on their definition, can take it back much further.

Sepp Holzer.was doing permaculture before he ever heard the word. To my knowledge, his farm is, by far, the best example of permaculture.

From 1938, Fukuoka began to practice and experiment with new techniques on organic citrus orchards and used the observations gained to develop the idea of "Natural Farming". Among other practices, he abandoned pruning an area of citrus trees, which caused the trees to become affected by insects and the branches to become entangled. He stated that the experience taught him the difference between nature and non-intervention.
