First these two series of little books (about 64 pages) - Scientist who have changed the world and People who have helped the world – are incredible well done. They are small but they provide a complete account of each person life with an outstanding historical background and future developments of his discoveries.. They are also full of pictures with full explanations and outlined quotes.
Sceweitzer was a famous musician and had two PhD before he was 30, then he decided to study medicine to help people (theology are just words I presume he understood!)
“In everything you recognize yourself. The tine beetle that lies dead in your path – it was a living creature, struggling for existence like yourself, rejoicing in the sun like you, knowing fear and pain like you. And now it is no more than decaying matter – which is what you will be sooner or later , too” A. Schweitzer.
Reverence for life was his belief.
