, studying to become a precision mechanic. His friend, J. Gustav Schmidt, studied chemistry at the Polytechnikum of Zurich (ETH), and their cooperation in conducting experiments led to Sandmeyer's close contact with chemistry. In 1882 Sandmeyer was made a chemistry lecturer at the ETH by Viktor Meyer. Meyer and Sandmeyer collaborated in studying the synthesis of thiophene, which Meyer had discovered earlier. When Meyer moved to the University of Göttingen, Sandmeyer followed, but then returned to Zürich after a year to work with
