In 1880, Bartholdi was able to obtain the services of the innovative designer and builder Gustave Eiffel. Eiffel and his structural engineer, Maurice Koechlin, decided to abandon the pier and instead build an iron truss tower. Eiffel opted not to use a completely rigid structure, which would force stresses to accumulate in the skin and lead eventually to cracking. A secondary skeleton was attached to the center pylon, then, to enable the statue to move slightly in the winds of New York Harbor and as the metal expanded on hot summer days, he loosely connected the support structure to the skin using flat iron bars which culminated in a mesh of metal straps, known as "saddles", that were riveted to the skin, providing firm support. In a labor-intensive process, each saddle had to be crafted individually. To prevent galvanic corrosion between the copper skin and the iron support structure, Eiffel insulated the skin with asbestos impregnated with shellac.
In January 1880, two of Tesla's uncles put together enough money to help him leave Gospić for Prague, where he was to study. He arrived too late to enroll at Charles-Ferdinand University; he had never studied Greek, a required subject; and he was illiterate in Czech, another required subject. Tesla did, however, attend lectures in philosophy at the university as an auditor but he did not receive grades for the courses.
A German immigrant named Feuchtwanger, from Frankfurt, in Hesse, allegedly pioneered the practice in the American midwest; there are several versions of the story with varying details. According to one account, Feuchtwanger's wife proposed the use of a bun in 1880: Feuchtwanger sold hot dogs on the streets of St. Louis, Missouri, and provided gloves to his customers so that they could handle the sausages without burning their hands. Losing money when customers did not return the gloves, Feuchtwanger's wife suggested serving the sausages in a roll instead.
The conflict is commonly referred to as the Boer War, since the First Boer War (December 1880 to March 1881) was a much smaller conflict. "Boer" (meaning farmer) is the common term for Afrikaans-speaking white South Africans descended from the Dutch East India Company's original settlers at the Cape of Good Hope. It is also known as the (Second) Anglo-Boer War among some South Africans. In Afrikaans it may be called the Anglo-Boereoorlog ("Anglo-Boer War"), Tweede Boereoorlog ("Second Boer War"), Tweede Vryheidsoorlog ("Second Freedom War") or Engelse oorlog ("English War").
