Charles Henri Pellegrini (28 July 1800 – 12 October 1875) was an Italian Argentine engineer, lithographer, painter, and architect.

His mother, Marguerite Berthet, was French, and his father, Bernardo Pellegrini, was a Swiss-Italian from Croglio, Canton Ticino, in the Italian-speaking part of Switzerland.

[3] Pellegrini was contracted as an engineer by Juan Larrea, a prominent Spanish Argentine merchant with interest in Bordeaux, by request of President Bernardino Rivadavia, and he arrived in Buenos Aires in November 1828.

He was hired by his fellow countryman, journalist and lithographer César Hipólito Bacle, in October 1830 as a portrait painter, and by the end of his commission in September 1831, he had earned around 17,000 pesos (around US$700).

[3] Following the overthrow of Governor Juan Manuel de Rosas in 1852, Pellegrini returned to Buenos Aires, founded the Revista del Plata (1853), and received numerous contracts as an engineer and architect.
