Paulus Manutius (Italian: Paolo Manuzio; 1512–1574) was a Venetian printer with a humanist education, the third son of the famous printer Aldus Manutius and his wife Maria Torresano.
As a young man Paulus Manutius moved to Venice to get an education and was well received by his father's old friends Pietro Bembo, Ramberto, and Egnatio. During Paulus' education his grandfather, Andrea Torresani and two uncles, Frederick and Francesco, carried on the Aldine Press. Andrea Torresani died in October of 1528 which brought disputes between Paulus and his uncles that halted the work of the press for four years. In 1533 Paulus assumed direction of his father's business. In that first year alone the press issued eleven titles. From 1536 to 1539 Paulus was involved in a lawsuit against his uncles in an effort to reclaim his father's italic type. In 1539 Paulus won.
Paulus was a passionate Ciceronian, and perhaps his chief contributions to scholarship are the corrected editions of Cicero's letters and orations (Epistolae ad familiares in 1540, Epistolae ad Atticum and Epistolae ad Marcum Iunium Brutum et ad Quintum Ciceronem fratrem in 1547), his own epistles in a Ciceronian style, and his Latin version of Demosthenes' Philippics (Demosthenis orationes quattuor contra Philippum, 1549). Throughout his life he combined the occupations of a scholar and a printer. As a scholar he is remembered for four elegant Latin treatises on Roman antiquities. His correct editions of the classics, printed in a splendid style, were highly esteemed, yet sales did not always support such productions; in 1556 he received for a time external support from the Venetian Academy founded by Federigo Badoaro. But Badoaro failed disgracefully in 1559, and the academy was extinct in 1562.
Meanwhile Paulus had established his brother, Antonio in a printing office and book shop at Bologna. Antonio died in 1559, having been a source of trouble and expense to Paulus during the last four years of his life. Other pecuniary embarrassments arose from a contract for supplying fish to Venice, into which Paulus had somewhat strangely entered with the government.
