Niccolò van Westerhout (also Nicola; December 17, 1857 – August 21, 1898) was an Italian composer.
Of Flemish origin, the family van Westerhout settled in Apulia in the seventeenth century, first in Bari and then in Monopoli. Nicola van Westerhout, grandfather of Niccolò, moved to Mola di Bari, where the composer himself and his father, Onofrio Augustine, were both born.
At the age of 13, van Westerhout composed an opera on the subject of Shakespeare's Julius Caesar, showing a remarkable musical talent. He was then helped, by the City Council of Mola di Bari, to move to Naples and attend the Conservatory of San Pietro a Majella, where he studied composition with Nicola De Giosa, Nicola D'Arienzo and Lauro Rossi. In Naples, he lived all his life.
The catalog of Niccolò van Westerhout, in addition to a wide array of chamber music and symphonic works, includes five operas: Tilde, which has been lost; Cimbelino, which was first performed at the Teatro Argentina in Rome in 1892; Fortunio, represented in Milan in 1894 (intended, originally, at the Teatro alla Scala in Milan, but then staged at the Teatro Lirico), Doña Flor, at the Teatro Municipale in Mola di Bari in 1896, Colomba, represented in 1925 at the Teatro San Carlo.
Westerhout died in Naples. Because of indigence besetting the family, the City of Naples paid for funeral and burial in the monumental Cemetery of Poggioreale.
After the death of Niccolò, his friends and his brother Vincent tried to offer his music compositions to various publishers but they were unable to bear the costs necessary for its distribution and his music was soon forgotten.
Recently, the tomb that housed the remains of the composer and some of his relatives has been identified at the Congregation of St. Raphael a Mater Dei. On 19 February 2007, the 150th anniversary of the birth, the bones were then transported to the city that gave him birth.
In Mola di Bari, the composer had been commemorated with the naming of a street and the municipal theater and the placing of a plaque at the site of the birthplace. Furthermore, in the central Piazza XX Settembre, a bronze statue by Molese sculptor Bruno Calvani, representing the protagonist of the Doña Flor, was placed. Lately, his remains were returned to Mola and now rest in the family tomb of the De Stasi family in the local cemetery
