E. F. Schumacher
Ernst Friedrich « Fritz » Schumacher (16 August 1911 – 4 September 1977) was an internationally influential economic thinker, statistician and economist in Britain, serving as Chief Economic Advisor to the UK National Coal Board for two decades.
His ideas became popularized in much of the English-speaking world during the 1970s. He is best known for his critique of Western economies and his proposals for human-scale, decentralized and appropriate technologies. According to The Times Literary Supplement, his 1973 book Small Is Beautiful: a study of economics as if people mattered is among the 100 most influential books published since World War II.(from Wikipedia)
