In our series, we have commemorated a number of Transylvanian-born scientists who have made a mark in the field of chemical and pharmaceutical sciences. One of them was Vilmos Hankó (1854-1923), born in Parajd, who had a unique career. He graduated as a chemistry teacher and received his doctorate from the University of Cluj-Napoca. His activities were extremely rich and varied. After Déva, he was a teacher and then director of one of the most famous high schools of Budapest for 36 years. In addition to his teaching activities, he has made significant contributions to the analysis and description of natural treasures (minerals, mineral waters) and to the modernization of science. He is the author of numerous books and has a very rich publication, textbook and editorial output. He was elected a corresponding member of the Hungarian Academy of Sciences in recognition of his work. He died 100 years ago in Budapest.
