This has been long needed and comes most aptly, with renewed interest and awareness of Pasteur and his contribution to pathology, bio-chemistry, agriculture, etc. The biography covers the whole of his life, with enough of his boyhood to give the necessary groundwork, and full details of his successive discoveries and the lifelong struggle to win recognition from a doubting world. A warmly friendly biography, making Pasteur a more likeable human figure than some of the adult works.
