Leopoldo Marco Antonio Caldani, an Italian anatomist, born in Bologna, Nov. 21, 1725, died in Padua, Dec. 30, 1813. He studied in his native place, devoting himself especially to anatomy, and became professor in the university in 1755. He distinguished himself by a series of experiments to prove the insensibility of the tendons, publishing the results in 1757 under the title of Lettera sulla insensibilitd ed irritability di alcune parti degli animali. This work gave him professional fame throughout Europe; but in Bologna itself he met with great opposition, and about 1760 he went to Venice, whence he was called to Padua as professor of theoretical medicine, and in 1771 he succeeded Morgagni as professor of anatomy, holding the office till his death. His principal works, besides that named above, are Icones Anatomicce (4 vols., Venice, 1801-'14), in the publication of which he was assisted by his nephew Florian, also an anatomist of great reputation, and Explicatio Iconum Anatomi-carum (1802-'14). He also published many less important works.
