Claudio López, 2nd Marquess of Comillas

Claudio López y Bru, 2nd Marquess of Comillas, GE (1853 in Barcelona – 1925 in Madrid), was a Spanish peer, businessman, and immensely rich shipping magnate and landowner. He inherited the companies his father Antonio López y López had founded.

For thirty years, from 1895 to 1925, the Marquess of Comillas dominated Catholic policy-making on labour relations.

Comillas sponsored Antoni Gaudí's trip to Tangier and Tétouan in 1892, where the architect was inspired by Franciscan José María Lerchundi to design a complex for Catholic Missions in Tangier. The project was never realized but was a source of inspiration for Gaudí's lifelong endeavor the Sagrada Família.
