The partnership between the stained glass window maker A. Rigalt and the architect J. Granell began around 1890. That is the year when their company, Rigalt, Granell i Cia, which continued in operation until 1922, is thought to have been set up. It was one of the most active stained glass window makers of the time and worked with designs by many of the most famous artists of Modernisme and on such buildings as the Palau de la Música Catalana (1905-1908; Palau de la Música, 4-6) and Casa Lleó Morera (1905; Passeig de Gràcia, 35), both by the architect L. Domènech i Montaner.
