William McDonough is an American architect and founding principal of William McDonough + Partners. Michael Braungart is a German chemist. Together they cofounded McDonough Braungart Design Chemistry, and in 2002 they coauthored Cradle to Cradle.
"Asking how a cherry tree would design an energy-efficient building is only one of the creative 'practices' that McDonough and Braungart spread before their readers. This book will give you renewed hope that, indeed, 'it is darkest before the dawn.'" --Carl Pope, executive director of the Sierra Club on Cradle to Cradle
"[McDonough and Braungart are] masters of holistic environmentalism . . . [They] have a knack for combining big ideas with commonsense practicality, which leaves readers feeling excited about the future." --Bruce Barcott, Outside Magazine on Cradle to Cradle
