Vladimir Grigoryevich Shukhov (; – 2 February 1939) was a Russian Empire and Soviet engineer-polymath, scientist and architect renowned for his pioneering works on new methods of analysis for structural engineering that led to breakthroughs in industrial design of the world's first hyperboloid structures, diagrid shell structures, tensile structures, gridshell structures, oil reservoirs, pipelines, boilers, ships and barges. He is also the inventor of the first cracking method. Besides the innovations he brought to the oil industry and the construction of numerous bridges and buildings, Shukhov was the inventor of a new family of doubly curved structural forms. These forms, based on non-Euclidean hyperbolic geometry, are known today as hyperboloids of revolution. Shukhov developed not only many varieties of light-weight hyperboloid towers and roof systems, but also the mathematics for their analysis. Shukhov is particularly reputed for his original designs of hyperboloid towers such as the Shukhov Tower. Biography Vladimir Shukhov was born in a town of Graivoron, Belgorod uezd, Kursk Governorate (in present-day Belgorod Oblast) into a petty noble family. His father Grigory Ivanovich Shukhov was a minor government official, promoted for his efforts in the Crimean War. For a while, Grigory served as Mayor of Graivoron and later as an administrator in Warsaw. In 1864 Vladimir entered Saint Petersburg gymnasium from which he graduated with distinction in 1871. During his high school years he showed mathematical talents, once demonstrating to his classmates and teacher an original proof of the Pythagorean theorem. The teacher praised his skills but he failed the grade for violating the textbook's guidelines. After graduating from the gymnasium, Shukhov entered the Imperial Moscow Technical School, in which his teachers included Pafnuty Chebyshev, Aleksey Letnikov, and Nikolay Zhukovsky. In the beginning of the year 1876 Shukhov graduated from school with distinction and a Gold Medal. Chebyshev offered him a job as a lecturer in mathematics at the Imperial Moscow Technical School, but Shukhov decided to seek a job in the engineering industry instead. In May 1876 Shukhov went to Philadelphia, to work on the Russian pavilion at the Centennial Exposition, the first official World's Fair in the United States, and to study the inner workings of the American construction and engineering industries. During his stay in the US, Shukhov came to know a Russian-American entrepreneur, Alexander Veniaminovich Bari who also worked on the organization of the Fair. In 1877 Shukhov returned to Russia and joined the
