1. Biography  (FR).  This is a very detailed description of Bernard's life, rather than his work. It was collated by Marie-Aymée Marduel, wife of a descendant of the Bernard family. The text is accompanied by numerous photographs of Bernard, his environment at different periods of his life and many documents. There is an excellent genealogy.

2. Wikipedia Summary (EN).  This reference site provides a good summary of his life and work, with a useful analysis of Bernard's "Introduction to the Study of Experimental Medicine".  A less-detailed summary is also available in French and in Italian.  

3. Who-Named-It  (EN).  A detailed summary of Bernard's life and work, with some quotations and links to descriptions of his eponymous syndromes.
