Bill Mollison, Australian researcher, author and biologist (b. 1928)
Bruce Charles "Bill" Mollison (4 May 1928 – 24 September 2016) was an Australian researcher, author, scientist, teacher and biologist. In 1981, he was awarded the Right Livelihood Award "for developing and promoting the theory and practice of permaculture".Permaculture (from "permanent agriculture") 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. This education system of "train the trainer", utilized through a formal Permaculture Design Course and Certification (PDC), has taught hundreds of thousands of people throughout the world how to grow food and be sustainable using permaculture design principles.
