Dear Exhibitors and Visitors

摘要

Dear Exhibitors and Visitors, Oberlin is a small town in Ohio. It is 6.703 kilometres from Mannheim. Anyone visiting both towns in 1886. exactly 130 years ago. would have been witness to two historic inventions; on 3 July 1886 Carl Benz "chugged" the world's first patented motorcar through the streets of the Baden metropolis. With it he wrote automobile history. Six days later at only 22 Charles Martin Hall submitted his patent specifications for the manufacture of aluminium using the electrolysis process. This was the moment the industrial extraction of the light metal was born.
