Latin America participated in the electric revolution which profoundly transformed the most developed Western economies between 1880 and 1930. The electrification of Latin America began relatively soon after these economies, but it was incapable of keeping up with them. Public electric lighting was introduced early in the big Latin American cities, where electric trams started running at almost the same time as in Europe, and electricity spread rapidly in the mining sector. In the most advanced countries or areas in the region, the manufacturing industry substituted the steam engine with the electric motor, following the example of industry in the United States and Europe. Nevertheless, towards 1930 electricity consumption per inhabitant for Latin America was far below that of the more advanced economies, and only the Latin American countries which lead the process of electrification had reached levels of electric consumption that were similar to those of the late industrialised European countries. One of the most striking features of the electric revolution in Latin America is rooted precisely in the enormous national differences. These differences are indicative of the great economic inequalities existing in the heart of the region and these nations highly diverse capacity for economic modernisation.

The success story of hydroelectricity long influenced and dominated Swiss scholarly literature devoted to the history of technology. This means of conducting power, which emerged at the end of the 19th century and is still dominating today, has attracted much more attention than technologies that have been shadowed by its success. In spite of their important contribution to Swiss economic development, the distribution networks of pressurized water have been neglected by scholars. This article contributes to close this historiographic gap by analyzing the introduction of pressurized water distribution in 1876 in Lausanne, in the context of the building of the first Swiss cable funicular between Lausanne and Ouchy. This article shows how pressurized water distribution transformed socio-economic practices in the urban areas in which it was adopted. Indeed, this innovation, which allowed the use of distant hydraulic resources, enabled the rationalization of industrial and artisanal production as well as improved the density of the urban industrial base. By facilitating the introduction of electric lighting, pressurized water networks played a key role in the early development, and further successes, of the Swiss hydroelectric industry.

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. THIS WEEK: Electric Lighting in the Iowa State Capitol BACKGROUND: REPORT OF COMMITTEE ON LIGHTING THE BUILDING AND GROUNDS WITH ELECTRICITY—1882 The Capitol Commissioners submitted biennial reports throughout the 15 years it took to build the Capitol (1871-1886). Often there were committees formed to investigate a certain phase of the construction. The following is the report of the Committee on Lighting. Note: The Capitol Commissioners determined the gas lighting to be the best choice in the 1880s. Less than 20 years later, the process began to convert the Capitol from gas to electric lighting. There was a period where both types of lighting were being used in the Capitol. The photograph of the 1904 apple harvest shows both electric and gas fixtures. The turn of the 20th century photograph of the library also shows chandeliers utilizing both gas and electricity. The photograph of the single fixture in the library is a mystery. It shows a fixture utilizing both gas and electricity, but no other photographs of the library exist where this fixture appears. Perhaps it was a prototype and never used in the Capitol.
