The Antunes family were Portuguese harpsichord- and early piano builders in the 18th and 19th centuries.
Their other existing instruments are signed only 'Antunes', probably because they were made by Manuel and Joaquin José working together.
These are a grand piano, very similar to their harpsichords in design and construction with an action like that of Bartolomeo Cristofori, made in 1767, now in the National Music Museum, Vermillion, South Dakota and a harpsichord similar to the others made in 1789 in the Museu da Música, Lisbon.
The existing instruments have been readily seized upon by harpsichordists as the ideal instruments upon which to play the music of Portuguese and Spanish baroque composers such as Carlos Seixas and Manuel Blasco de Nebra.
