“…Two of the most influential researchers in the history of catalysis in Japan, Setsuro Tamaru, Tokyo (Kenzi Tamaru's father) and Juro Horiuti, Sapporo, spent considerable time abroad. In fact, both had been performing research at the Kaiser‐Wilhelm‐Institute for Physical and Electrochemistry, which is now known as the Fritz‐Haber Institute of the Max‐Planck Society in Berlin: Setsuro Tamaru, under Fritz Haber's guidance, before in Karlsruhe, and after the foundation of the institute in 1911 in Berlin, and Juro Horiuti under Michael Polanyi's guidance during the twenties of the last century in Berlin . For the 1980 International Catalysis Congress, the late Juro Horiuti is listed as part of the Advisory Board, and Kenzi Tamaru was one of the Vice‐Chairmen of the Executive Committee.…”
