63. Prince Charles — Prince of Wales and founder of Duchy Originals (now Duchy Organic)

It all started with an oaten biscuit.

25 years ago, Prince Charles set up an organic food brand to sell the produce grown on the Prince of Wales Highgrove House estate.

Today, it is the second largest organic brand in the UK with over 300 products on the shelves in Waitrose, which is the brand's supermarket partner. Sales of Waitrose Duchy Organic products provide a donation to The Prince of Wales's Charitable Foundation, which supports causes across the UK in education, community support, conservation, and more.
