Antônio Carlos de Mariz e Barros

Antônio Carlos de Mariz e Barros (7 March 1835 – 28 March 1866) was a Brazilian soldier, combatant in the Uruguayan Campaign and in the Paraguayan War. Mariz e Barros was the son of chief of squad Joaquim José Inácio, the viscount of Inhaúma, and his wife, Maria José de Mariz Sarmento. He studied at the Brazilian Navy Academy, having reached the rank of first lieutenant.

Mariz e Barros temporarily commanded the yacht Paraibano, and effectively the gunboat Campista and the corvettes Belmonte, Recife, and the battleship Tamandaré, gaining prominence on the battlefield during the Uruguay Campaign, where he carried out a successful raid on Paysandú and another against the Sevastopol fort. He was awarded the Order of the Rose after accompanying emperor Pedro II on his journey to the North and the Legion of Honor for saving a French barge that was about to sink on the rocks of the Fort of Laje.

Mariz e Barros died at 1 am on 28 March 1866, during the Paraguayan War. His death occurred as a result of injuries resulting from the explosion caused by one of the cannon projectiles fired by the Fortress of Itapirú that hit Tamandaré's casemate. Before dying, he suffered an amputation during which he would have smoked a cigar. In his honor, the Municipal Chamber of Rio de Janeiro changed the name of Nova do Imperador Street, in the neighborhood of Tijuca, to Mariz e Barros on 16 November 1874. The corvette Mariz e Barros was also named in his honor, in addition to two destroyers.
