Gregory P. Tschebotarioff
Gregory Porphyriewitch Tschebotarioff (* February 15, 1899 in Pavlovsk, † April 22, 1985 in Holland ( Pennsylvania)) was an American civil engineer for geotechnical engineering with Russian roots.
Life
Tschebotarioffs father was an officer in the Guards battery of the Don Cossacks, stationed in Pavlovsk, and his mother was the daughter of a medical officer and friend of the Tsarina, who worked with this in World War I in Tsarskoye Selo as a nurse. He was an artillery lieutenant in the First World War from 1916 to 1917 in the Russian army and then to 1920 with the White Army ( Don Army ) against the Red Army in the aftermath of the Russian Revolution. After he had lost his parents by typhoid and had to care for his sister, he went to Germany to study engineering, he had already begun in Russia. He studied at the Technical University of Berlin, where he was awarded a degree in 1925 and received his doctorate. After that, he worked in structural engineering, among others in Paris, Berlin, Bremen and Cairo. In 1929 he went to Karl von Terzaghi to Vienna and specialized in foundation engineering. Seven years he worked as an engineer in Cairo on behalf of the Egyptian government as a fundamental civil engineer. In 1936 he participated in the First World Congress on Soil Mechanics and Geotechnical part in Harvard and was from 1937 and Professor of Soil Mechanics and Foundation was at Princeton University, where he built a soil mechanics laboratory. In 1964 he retired.
He became known through experiments on retaining walls and shoreline structures on a large scale, which he carried out for the Office of Naval Research and the Office for port construction ( Bureau of Yards and Docks ). He also carried out early Soil dynamics experiments for the Civil Aviation Authority (Civil Aernonautics Administration).
Even in his high school teacher time he worked as a consulting engineer and in 1955 a partner in the engineering firm King and Gavaris in New York, where he was responsible for foundation engineering until 1970 and even then was still a consultant.
He wrote a popular in the U.S. soil mechanics textbook.
In 1941 he became a U.S. citizen. In 1964, he published his memoirs, in which he also published parts of his mother Valentina Ivanovna Chebotaryova the diary. She died in 1919 of typhus, which she won in nursing at the hospital, so that Tschebotarioff had to care for his little sister Valentine, he brought to her godmother Sophie of Medum to Berlin. He married 1939 Florentine Bill whose brother married his sister Valentine.
Since he publicly spoke out in the U.S. against a hostile Russia in his eyes distortion of Russian history, he got in the McCarthy era, despite his service in the White Army difficulty.
In 1959 he became an honorary doctorate in Belgien.1977 he became an honorary member of the American Society of Civil Engineers ( ASCE ), the Terzaghi Award he received. In 1976 he held the Martin Kapp Lecture ( Half a century of soil mechanics ). His estate is at Purdue University, including the manuscript of his last unpublished book Civil Engineering on four continents.
