http://www.cartage.org.lb/en/themes/Biographies/MainBiographies/L/Lobachevsky/1.
Lobachevsky, Nikolai Ivanovich
In Euclid's system, two parallel lines will remain equidistant from each other, whereas in Lobachevskian geometry, the two lines will approach zero in one direction and infinity in the other. In Euclidean geometry the sum of the angles of a triangle is always equal to the sum of two right angles; in Lobachevskian geometry, the sum of the angles is always less than the sum of two right angles. In Lobachevskian space, also, two geometric figures cannot have the same shape but different sizes.
Lobachevsky was born at Nizhni-Novgorod and studied at the University of Kazan, Tatarstan. He taught there from 1814, becoming professor 1822 and rector of the university 1827-47. He also took on administrative work for the government.
Lobachevsky developed non-Euclidean geometry between 1826 and 1856. He came to see that it was not contradictory to speak of a geometry in which all Euclid's postulates except the fifth held true. By including imaginary numbers, he made geometry more general, and Euclid's geometry took on the appearance of a special case of a wider system.

    Pirogov, Nikolai Ivanovich [nyik u l I E u vich pir O Pronunciation Key Pirogov, Nikolai Ivanovich , Russian surgeon, b. Moscow. He entered the Univ. of Moscow at the age of 14 and completed the medical curriculum at 17. He then studied in Germany, receiving a doctor of philosophy degree at Dorpat, where he served as professor of surgery from 1836 to 1840. He first gained prominence in the United States for his anatomical studies on arteries and fascia. In 1840 he returned to Russia and became professor of hospital surgery at the Military Medical Academy at St. Petersburg. The opening of the Crimean War in 1854 found him in Sevastopol. Considered the founder of field surgery, he devised the plaster cast, first used successfully in the Sevastopol campaign, and the Pirogov amputation, a method of severing the foot so that part of the heel bone is left in the stump to give added support to the lower ends of the leg bones. He was one of the first to use ether as an anesthetic (1847) and was the author of many scientific treatises. The Columbia Electronic Encyclopedia

List of Russians
This is a list of people associated with Imperial Russia , the Soviet Union , and Russia of today. For a long time Russia was a multinational country, and many people of different nationalities contributed to its culture, to its glory, and to its sorrow. They may be Georgians Jews Poles Moors , Udege, Tatars Belarussians Germans ,... Sometimes we don't know their exact ancestry. Sometimes their formal nationality was written down at random or for political or other reasons. They may have emigrated or immigrated , and thus may appear in other "Lists of...", but nevertheless their names are linked to the words "Russia", "Russian", whether with pride, with shame, or with pain.

Murió: 24 febrero de 1856 en Kazan (Rusia) Lobachevsky nació en una familia pobre, fueron tres hermanos. Su padre murió cuando Lobachevsky tenía 7 años. A la muerte de su padre, la familia se trasladó a Kazan, cerca de Siberia. Lobachevsky entró en el Gymnasium (el equivalente a nuestros Institutos) en 1802. En 1807 entró en la Universidad de Kazan, abierta dos años antes. La intención original de Lobachevsky era estudiar Medicina, pero cambió de idea y estudió Matemáticas y Física. Los profesores eran excelentes y provenían de Alemania. Uno de los profesores, Bartels, pronto se interesó por Lobachevsky. En 1811 se graduó, en 1814 fue propuesto para profesor ayudante, en 1816 profesor extraordinario y en 1822 profesor a tiempo completo. En 1822 le encargaron la supervisión de la construcción de los edificios de la Universidad. A pesar de las dificultades políticas, debidas a la llegada de las ideas de La Revolución Francesa, que provocaron que muchos profesores, entre ellos Bartels, tuvieran que irse, Lobachevsky hizo grandes cosas por la Universidad.
