Felisberto Caldeira Brant Pontes de Oliveira Horta, the Marquis of Barbacena (19 September 1772 – 13 June 1842) was a Brazilian soldier and statesman of both Portugal and the Empire of Brazil.

In 1807, during the French invasion of Portugal, the Prince Regent, Dom João VI, fled to Brazil with a large retinue.

There, he became a pioneer in the field of steam transportation, developing such an interest in the method that he was granted official authorization to study it.

[3] By 1821, the Prince Regent had returned to Portugal, leaving his son Dom Pedro I in control of Brazil.

Brant supported Dom Pedro, now the Emperor, being sent on a diplomatic mission to London by José Bonifácio, the minister for both internal and foreign affairs.
