The last decades of the 19th century and the first years of the 20th were a time when electrification became fashionable. The realization that the Pyrenean waterfalls could be a source of energy forever changed both the landscape and the country's business ecosystem. Some key figures in this process were Carles Montañès Criquillion, Frederick S. Pearson, and Emili Riu Periquet, among others. But less well-known today, yet with the same entrepreneurial spirit as the others, was the engineer Lluís Rouvière Bula, who not only dedicated himself to electricity but also designed highly significant railway projects.
