Pierre-Dominique Bazaine

Pierre-Dominique Bazaine (1786 - 1838) (Пётр Петрович Базен) was a French scientist and engineer. He was educated at the École Polytechnique in Paris as an engineer. At the request of Alexander I of Russia he was sent to Russia by Napoleon I as an army officer in the engineering corps to set up an institute for the education of transportation engineers, and in 1824 he became its director. Bazaine remained in Russia until 1834, organizing transportation routes and directing the work of inland navigation. He was responsible for many of the bridges of St. Petersburg and its outskirts (including a number of the small and elegant lightweight iron bridges in the Summer Garden), as well as other major civil engineering projects, including flood protection. He received many Honours and Awards for his extensive contribution to the infrastructure of Russia, as well as Honourary Fellowship of a number of science academies across Europe for his ground-breaking mathematical theses. He finally returned to France in 1834 and died in Paris aged 52 in 1838.

Career

He was born 13 January 1786, in the town of Scy-sur-Moselle, son of Pierre Bazaine (1760-1832) and Francoise Gilbert. Educated in Paris, graduate of L'Ecole Polytechnique and the School of Bridges and Roads. Initially he practised as an Engineer in Italy and Southern France. His outstanding abilities drew the attention of Napoleon I who subsequently recommended him to the Russian Emperor Czar Alexander I, along with engineers Fabrom, Destremom and Potier, to take up senior posts in the Russia corps of Civil Engineers. Bazaine arrived in St.Petersburg, Russia in 1810 with Lieutenant Fabrom but due war with France, did not immediately take up his post. Instead he was sent to Odessa under the Governor-General of the Duke de Richelieu, where his first work was at the Russian port of Evpatoriya. He was then sent to Yaroslavl, to Poshehone and then in 1812 due to the war with France, he was deported to Eastern Siberia, where he spent more than two years. Bazaine devoted himself entirely to science and analytics whilst in Siberia, writing his great treatise on differential calculus and several memoirs about plane geometry and properties of various lengths in three dimensions. In 1815, with the end of war in Europe, he returned to St. Petersburg where with the new rank of Colonel, he was appointed Chair Professor of Higher Analytics and Mechanics at the Civil Engineering Institute. In 1820, he was promoted to Major-General and in 1823 he was appointed a member of the Council Ways and Communications, being made Inspector-General. In January 1824, He became Director of the Imperial Russian Academy of Sciences, St. Petersburg, and also Chairman of the Committee for Buildings and Hydraulic works in St.Petersburg. In 1828, Bazaine returned to France but on his return to Russia was promoted to Lieutenant General on 1 April 1830. Bazaine's structural engineering works were extensive and much remains in the historic infrastructure in Russia. His main works are:

  • the Obvodny canal in St. Petersburg;
  • water supply Yamskoy Slobody and Tavrichesky Garden;
  • Shlisselbourg granite building locks (for which he was awarded the Order of White Eagle).

For the last buildings he wrote a remarkable treatise, in which he argued for the possibility of huge water savings in the Ladoga Canal, by ships passing through its locks: "Mémoire sur les bassins d'épargne" (napech. in Zapiskah Acad. Sciences). From 1820-1832 Bazaines prominent works include: rebuilding St. Isaac's Cathedral and on the same design building several other churches; the first chain bridge in Russia at Ekaterina park; restructuring, under his personal supervision, Ohtenskogo powder factory; deepening the river estuary at Neva and its channels; erection of buildings of the Senate and the Synod; rebuilding the University; the remarkable construction of the dome over the cathedral of St.Trinity (at the St. Petersburg side), 87 feet in diameter. Some of the bridges in St.Petersburg which he is responsible for include Demidov Bridge and First Engineer Bridge. These and many other constructions brought Bazaine several awards: in addition to the above, he was awarded the Order of St.Vladimir, the Grand Cross of St.Alexander Nevsky; Commander of the French Legion of Honour, Prussian Order of the Red Eagle (1st Class). He was elected an honorary fellow of St Petersburg Academy and the Science Academies of Turin, Munich, Stockholm and St Petersburg. He conceived the constructions of the floors of the Winter Palace, the Theater Alexandrinski and the Cathedral of the St.Trinidad. He directed the works of construction of the Obvodni channel, the buildings Senate and Synod of the sluices of Shlisselbourg, of the hydraulic constructions of the Okhtinski factory. He also masterminded the first project to protect St.Petersburg against flooding. He writes several treaties on mathematics, transportation and the civil genius including a monograph on steamboats and their use in navigating canals and rivers. He was made a member of the Mineralogical Society of St. Petersburg University in 1834. Deteriorating health prompted Bazaine to resign, and in 1834 he was transferred to the corps of military engineers, but heart disease forced Bazaine to return to Paris where he died on 29 September 1838 and was buried at the cemetery Monmartre.

Family

He married Marie-Madeleine Vasseur and they had 3 children, 2 sons and a daughter. His daughter Melanie (1808-1852) married the engineer Benoît Paul Émile Clapeyron in 1834. His eldest son, also Pierre-Dominique Bazaine (known as Adolphe) (1809-1893) was also a Civil Engineer and an important Railway engineer in the 1840s. He married an English woman Elizabeth Hayter. His second son was Francois Achille Bazaine, a distinguished soldier who became a Marshal of France.
