Henri Dominique Lacordaire: A Biographical Sketch is a book by H.L. Sidney Lear published in 1882 (or 1892, depending on the edition) that provides a detailed biography of the 19th-century French Dominican priest, preacher, journalist, and political activist Jean-Baptiste-Henri Lacordaire. The book covers Lacordaire's early life, his theological and political views, his role in the French Revolution and his involvement in social issues, and his eventual return to the Dominican order. It is considered a valuable and culturally important resource for understanding the life of this key figure in French Catholicism.
