Gábor Kornél Tolnai mass-production. Kornél Tolnai often ordered his tapes from the American electronics company Ampex Corporation in the 1950s and 1960s. Kornél Tolnai often visited a factory in Ludwigshafen am Rhein (Rhineland-Palatinate in Germany) for his business with the company. There he had contacts with BASF, the largest chemical company in the world. BASF SE is a German chemical company, founded in 1865, and SE stands for Societas Europea. The company is a pioneer in the chemical industry and has operations worldwide. 1925-1952 it was part of IG Farben. "BASF" originally stood for Badische Anilin- und Soda-Fabrik (Baden Aniline and Soda Factory).
Aniline obtained a base that he named "benzidam". In 1843, August Wilhelm von Hofmann showed that these were all the same substance, known thereafter as "phenylamine" or "aniline". In 1856, whilst trying to synthesise quinine, von Hofmann's student William Henry Perkin discovered mauveine and went into industry producing the first commercial synthetic dye. Other aniline dyes followed, such as fuchsin, safranin, and induline. At the time of mauveine's discovery, aniline was expensive. Soon thereafter, applying a method reported in 1854 by Antoine Béchamp, it was prepared "by the ton". The Béchamp reduction enabled the evolution of a massive dye industry in
