Both relate to the case of the Angola Three -- Albert Woodfox, Herman Wallace, and the recently released Robert King Wilkerson, three black political prisoners who have been held in solitary confinement in the Louisiana prison for 30 years and counting.
The case is a human rights cause celebre -- and Roddick, with her dogged pursuit has had a hand in keeping it in the public eye.
Four days after writing those two posts, the founder of Body Shop, and one of the best known environmental and human rights activists in the world, lay dead in a Chichester, England hospital, aged 64, of Hepatitis C.
Her story began in 1976 when, with two daughters to support while her husband Gordon travelled in the United States, she started a small cosmetics boutique in Brighton.
She had, she was to confess, no idea at the time how to run a business, no formal training, and no business plan.
What she had was an idea, derived at least in part from war-time lessons learned from her mother. During the stringent rationing of World War II, Roddick remembered, the family had 'reused everything, refilled everything, recycled all we could.'
From that seed, sprang the idea of creating a range of organic cosmetic and food products - an idea so far ahead of its time that her early customers had no idea they were frontrunners of the growing global 'green' trend.
The company's USP remained simple, even as it continued to grow: every product it sold would be all natural, would come in recyclable packaging, and would have never been tested on animals.
Explaining her philosophy, she wrote in the Third Way magazine that 'The original Body Shop was a series of brilliant accidents. It had a great smell, it had a funky name. It was positioned between two funeral parlours -- that always caused controversy. It was incredibly sensuous. It was 1976, the year of the heat wave, so there was a lot of flesh around.
'We knew about storytelling then, so all the products had stories. We recycled everything, not because we were environmentally friendly but because we didn't have enough bottles. It was a good idea. What was unique about it, with no intent at all, no marketing nous, was that it translated across cultures, across geographical barriers and social structures. It wasn't a sophisticated plan, it just happened like that.'
When French fashion brand L'Oreal bought over The Body Shop in March 2006, the company had grown into a network of over 2,000 stores, in over 50 countries, with an estimated 77 million customers -- all this without ever diluting its reputation for environmental consciousness and determinedly green beauty and health products.
'We have,' Roddick said while announcing the sale, 'no clue how we got here'
In a signed article in Newsweek early this year, Roddick wrote that she had sold her business so she could dedicate what remained of her life to the causes that interested her: human rights, and environmental protection.
She then began donating her $100 million-plus fortune to the causes that were closest to her heart; `I don't want to die rich', she said in explanation.
In 2003, she was named Dame Commander of the Order of the British Empire, and officially styled Dame Anita Roddick DBE; she had earlier, in 1984, been named an Officer of the Order of the British Empire.
She has, to her name, more awards than you can count -- what is striking, and perhaps defining, is that these awards fall neatly into two categories: those given for her business acumen, and those she received for her activism in the fields of environment and human rights.
This, perhaps, is her legacy to the world: In the life she lived and the business she built from scratch into an iconic global brand, she demonstrated beyond doubt that it is in fact possible to mix oil and water, a profitable business and heartfelt social concern.
