The world of books held its breath when Lennart Nilsson revealed one of the greatest secrets of human existence in 1965 with "A Child is Born": life before birth. His photos taken in the womb traveled around the world. Nearly 40 years later, the book was completely revised. New breathtaking images, captured with the latest techniques, allowed us to follow the individual developmental stages of the baby even more closely and made visible processes that science had only just discovered. The book became a million-copy bestseller. It has now been revised again, with comprehensive textual updates and new reportage photos on pregnancy and childbirth. The standard work of the multiple award-winning photographer Lennart Nilsson remains unmatched in the quality, significance, and fascination of its images.
