The Oslé brothers, Llucià (1880-1951) and Miquel (1879-1960), started out by frequenting the workshop of Josep Llimona. Later on they attended La Llotja, the Barcelona School of Fine Arts, and were students of the sculptor Josep Montserrat. To begin with they worked separately, but the parallel paths followed by their careers led them eventually to produce a number of works together.

Llucià was awarded many honourable mentions and prizes at various fine arts exhibitions and became very popular in the United States. He also sporadically turned his hand to humorous sculpture and taught at the Sant Jordi School of Fine Arts.

Miquel, with the same training as his brother, worked for Foneria Masriera i Campins making decorative works and studied at various private academies before travelling outside Catalonia.

It was the critic R. Casellas who brought them to public attention at the start of their careers. The first pieces they made took social themes for their subject matter - figures of workers and labourers - and adopted the Modernista aesthetic as regards their formal features. During their later period they concentrated on more monumental art, which resulted in their losing favour in the art world.

The works by these brothers in Barcelona include the reliefs on the Monument to Jacint Verdaguer (1914; Plaça de Jacint Verdaguer), designed by J.M. Pericas; the sculptures Treball (Labour) and Saviesa (Wisdom), by Llucià and Miquel, respectively, (1928-1929), among the sculptures of the fountain in Plaça de Catalunya; the sculptures of the fountain in Plaça d'Espanya, and the monument to Eusebi Gu?ell in Colònia Gu?ell (1890; Claudi Gu?ell, s/n, Santa Coloma de Cervelló). There is also a lot of work by them in other towns elsewhere in Spain.
