Lawrence D. Hills
Lawrence D. Hills (1911-1991) was a British horticulturalist, journalist, and writer, founder of the Henry Doubleday Research Association (HDRA). "As an horticulturalist he had a keen interest in organic growing, but he earned his living as a freelance journalist writing for The Observer, Punch and The Countryman. Whilst researching a book called Russian Comfrey, he discovered that the plant grown widely in Britain today was introduced in the nineteenth century by a Quaker smallholder named Henry Doubleday."
