“In 1897 Simon Patiño purchased La Salvadora mine near the village of Uncia, east of Oruro, which eventually became the world’s most productive tin source. Patiño’s fortunes snowballed and by 1924 he had gained control of about 50% of the nation’s tin output.” (lonelyplanet)
“In 1824, Diego de Almeyda made the discovery of the large natural deposits of copper in the area near Chanaral, and was the first in the mining industry in Chile to export it. For this reason, the town was founded October 26, 1833 as Chañaral de las Ánimas ("Chañar field of the Souls"). A few of years later, Pedro Lujan discovered ore at El Salado, where a mine was built. In 1836, a shipping port promising raw material was constructed. The great boom Chañaral began in 1860 when A. Edwards & Company was inaugurated where an inn exists today.” (Wikipedia)
“The Keystone View Company was founded in 1892 by B. L. Singley in Meadville, Pennsylvania…it rapidly improved and eventually became not only the world's largest but also the best view company. In the formative days Singley took all the images; later there were dozens of staff photographers…They developed the technique of consistently producing beautifully clear, crisp prints which were a delight to view; originally they were mounted on tan curved cards and later on their trade-mark dark gray curved mounts. The company also emphasized the use of informative text on the back of the views, and popularized the concept of boxed sets which had been innovated by the Underwood Brothers.” (Yellowstone Stereoview Page)
