Nicolás Rivero y Alonso (15 December 1886-19 April 1946) was a Cuban journalist and diplomat.
In 1909, he was a Cuban consular to Marseille, and one year later he became the inspector of consulates and administrator of the National Bank of Cuba. In 1919, after his father, Nicolás Rivero y Muñiz, was posthumously granted the title of the 1st Count of Rivero, he automatically became the 2nd Count of Rivero[1] and also became the Administrator of his father's newspaper, Diario de la Marina, for a time.[2] [3]
In 1929, Rivero was appointed the position of Honorary Consul General of Hungary to Havana.[4] His brother was José Ignacio Rivero Alonso ("Pepín" Rivero) who became the director of Diario de la Marina while Nicolás Rivero pursued the life of Cuban diplomacy.[5] In 1935, Rivero became the first Cuban ambassador to the Holy See. He lived in Rome while serving in this post, at the official residence of the ambassador next to the Holy See, and also served as the 3rd Cuban ambassador to Austria.[6]
