This biography represents a comprehensive, accessible account of the great eighteenth-century French chemist and administrator, Antoine Lavoisier.

Lavoisier was, by virtue of his achievements and the events in which he was involved, an historical figure of extraordinary importance. His biography illuminates the rise of modern science and the history of the French Revolution. Antoine Lavoisier provides the reader with a vivid, informed image of the man, his achievement and the tumultuous age in which he lived.
