Boris Nikolaevich Delaunay or Delone (Russian: Борис Николаевич Делоне; March 15, 1890 – July 17, 1980) was one of the first Russian mountain climbers and a Soviet/Russian mathematician, and the father of physicist Nikolai Borisovich Delone.
The spelling Delone is a straightforward transliteration from the Cyrillic alphabet he often used in recent publications, while Delaunay is French language version he used in the early French and German publications.
Boris Delone got his surname from his ancestor French Army officer de Launay, who was captured in Russia during the Napoleon's invasion of 1812. De Launay was a nephew of the Bastille governor marquis de Launay, married a woman from the Tukhachevsky noble family, and stayed in Russia.[1]
When Boris was a young boy his family spent summers in the Alps where he learned mountain climbing.[2] By 1913 he became one of the top three Russian mountain climbers. After the Russian revolution he climbed mountains in the Caucasus and Altai. One of the mountains (4300 m) near Belukha is named after him. In the 1930s he was among the first to receive a qualification of Master of mountain climbing of the USSR. Future Nobel laureate in physics Igor Tamm was his associate in setting tourist camps in the mountains.
Boris Delaunay worked in the fields of modern algebra, the geometry of numbers. He used the results of Yevgraf Fyodorov, Hermann Minkowski, Georgy Voronoy, and others in his development of modern mathematical crystallography and general mathematical model of crystals.[3] He invented what is now called Delaunay triangulation in 1934.[4] Among his best students are the mathematicians Aleksandr Aleksandrov and Igor Shafarevich.
