Vladimir Shukhov invented hyperboloid towers and was also the first one to use them in construction. For the 1896 All-Russia industrial and art exhibition in Nizhny Novgorod he built the 37-meter steel diagrid tower, which became the first hyperboloid structure in the world. The hyperboloid steel gridshell attracted attention of European observers. In particular, the British magazine "The Engineer" published an article about the tower.
