Hubertus Christiaan (Hubert) de Blanck (June 14, 1856[1] – November 28, 1932[2]) was a Dutch-born professor, pianist, and composer who spent the better part of his life in Cuba.

After playing a concert at Brussels' Royal Palace, King Leopold II awarded him a scholarship to study at whichever conservatory he chose.

After the performance it was reported in the Saxonian Journal that the Chancellor gave De Blanck a gold encrusted ruby, a testament to his admiration of the pianist.

A music critic from Copenhagen commented that the pianist "received fervent and abundant applause, the likes of which our reserved public is not accustomed to giving".

They performed a number of times at the Teatro Colón, and on November 16, they took part in a large benefit concert, the proceeds of which funded the creation of a commemorative monument celebrating centenary of the introduction of 'imprenta' in Buenos Aires.

From this union were born six Cuban children: five sons, Guillermo (Willy), Huberto, Armando, Florencio, Narciso, and a daughter, Rosario.

Taking advantage of the Christmas vacation afforded him by the college, De Blanck visited Havana for the first time in December 1882 along with his wife.

Cuba's most famous artists, among them Ignacio Cervantes, Pablo Desvernine, and Nicolás Ruiz Espadero, applauded the visiting pianist.

In March 1884, he organized and conducted, with assistance from the Governor General, a fundraising festival in the 'Tacon' theater to raise money for the construction of the 'Reina Mercedes' hospital.

He named Gabriel Morales Valverde ('Edgardo') conservatory secretary and designated Anselmo Lopez, Ernesto Edelmann, Jose Mungol, Tomas Ruiz, Juan Miguel Joval, and Mariano Cuero its first teachers.

The new conservatory received funding from 'La Caridad Del Cerro', 'La Disputacion Provincial', the 'Real Sociedad Económica', the National Government and the city council of La Habana, and opened that September 1885.

Widely acclaimed in Cuba during his lifetime for his significant contribution to the country's culture, he has since been honored with his image on a Cuban postage stamp.
