In 1902, Francesca Morera i Ortiz commissioned Lluís Domènech i Montaner to remodel a building she had inherited from her uncle, Antoni Morera, on 35 Passeig de Gràcia in Barcelona. Francesca Morera died in 1904, and her son, Albert Lleó i Morera, took charge of the project’s completion.
Francesca Morera i Ortiz, the daughter of Joan Morera i Busó and Baldomera Ortiz i Figueroa, was born in Barcelona in 1853. She came from a family of overseas merchants who had made their fortune in the Americas. She married Albert Lleó i Dubosch, but legally separated in 1881 after having had only one son, Albert Lleó i Morera.
Albert Lleó i Morera was born in Barcelona on October 29th, 1873. He was a brilliant student, receiving a Ph.D. in Medicine and Surgery in 1902 in Madrid. He devoted his life to microbiology and chemical analysis, serving as the Hospital de la Santa Creu i Sant Pau's laboratory director.
As a member of the illustrious Catalan bourgeoisie, he also had other interests, such as combustion engines. He even patented an aviation engine, but it did not have the desired success.
On October 29th, 1898 he married Olinta Puiguriguer i Palmarola, with whom he had three children. His second son died just after birth, which explains the presence of sculptural reliefs in the main floor's hallway that tell the story of "The Nurse of the Child King". Albert Lleó i Morera died on December 22nd, 1929.
His son, Albert Lleó i Puiguriguer, studied law and also became a fan of the world of motors: automobile racing and aviation. He was also in charge of managing the family's estate. In 1943, the family sold the building to Sociedad Mercantil Bilbao, an insurance company.
