El Congreso de Karlsruhe. Los inicios de una comunidad científica

In this article we analyze the epistemological and historical role of the Karlsruhe congress in the recognition of Chemistry as a scientific discipline. The event took place in Karlsruhe, Germany, it was held in 1860 and was attended by the most eminent chemists at that time in order to make agreements on the concepts of atom, molecule and equivalent and at the same time create a rational chemical notation for compounds. At the end of the Congress they had not made agreements, the assembly's deliberations would not be of a nature such as to reconcile all opinions and eliminate all disagreements immediately. Nevertheless, such works paved the way for a much desired agreement between chemists in the future and for the beginning of a scientific community. One of the most distinguished participants in the congress was Stanislao Cannízzaro whose lecture was a starting point for the great contribution in education, textbooks and specialized magazines.
