Editing Stephen Timoshenko (section)

===United States===
In 1922, Timoshenko moved to the [[United States]] where he worked for the [[Westinghouse Electric Corporation]] from 1923 to 1927, after which he became a faculty professor in the [[University of Michigan]] where he created the first [[bachelor's degree|bachelor]]'s and [[Doctorate|doctoral]] programs in engineering mechanics. His textbooks have been published in 36 languages. His first textbooks and papers were written in [[Russian language|Russian]]; later in his life, he published mostly in [[English language|English]]. In 1928 he was an Invited Speaker of the [[International Congress of Mathematicians|ICM]] in Bologna.<ref>{{cite book|author=Timoshenko, S.|chapter=The stiffness of suspension bridges|title=''In:'' Atti del Congresso Internazionale dei Matematici: Bologna del 3 al 10 de settembre di 1928|volume=6|pages=305–306}}</ref> From 1936 onward he was a professor at [[Stanford University]]. He was elected to the [[American Philosophical Society]] in 1939 and the United States [[National Academy of Sciences]] in 1940.<ref>{{Cite web |title=Stephen P.

Timoshenko's younger brothers, architect Serhii ([[Sergius Timoshenko]], Ukrainian Minister of Transport, participant in the 1921 [[Second Winter Campaign]] against the Soviet regime, and member of the Polish Senate),<ref>{{Cite web |title=Tymoshenko, Serhii |url=https://www.encyclopediaofukraine.com/display.asp?linkpath=pages%5CT%5CY%5CTymoshenkoSerhii.htm |access-date=2024-09-23 |website=www.encyclopediaofukraine.com}}</ref><ref>{{Cite Q|Q106642728}}</ref> and economist Volodymyr, both immigrated to the United States as well.

In 1957, [[American Society of Mechanical Engineers|ASME]] established a medal named after Stephen Timoshenko; he became its first recipient. The [[Timoshenko Medal]] honors Stephen P. Timoshenko as the world-renowned authority in the field of [[mechanical engineering]] and it commemorates his contributions as author and teacher. The Timoshenko Medal is given annually for distinguished contributions in applied mechanics. In 1960 he moved to [[Wuppertal]], [[West Germany]] to be with his daughter.

In addition to his [[textbook]]s, in 1963 Timoshenko wrote a book ''Engineering Education in Russia'' and an [[autobiography]], ''As I Remember'' in the Russian language. It was translated into English in 1968 <ref name=AIR/> by sponsorship of Stanford University.  [[Jacob Pieter Den Hartog]], who was Timoshenko's co-worker in the early 1920s at Westinghouse, wrote a review in the magazine ''Science'' <ref>Den Hartog J.P.,1968. Odyssey of an engineer, Science, Vol. 160, pp.1102-1103</ref> stating that   "between 1922 and 1962 he [S.P. Timoshenko] wrote a dozen books on all aspects of engineering mechanics, which are in their third or fourth U.S. edition and which have been translated into half a dozen foreign languages each, so that his name as an author and scholar is known to nearly every mechanical and civil engineer in the entire world.. Then, Den Hartog stressed: "There is no question that Timoshenko did much for America. It is an equally obvious truth that America did much for Timoshenko, as it did for millions of other immigrants for all over the world. However, our autobiographer has never admitted as much to his associates and pupils who, like myself often have been pained by his casual statements in conversation. That pain is not diminished by reading these statements on the printed page and one would have wished for a little less acid and a little more human kindness."

The celebrated theory that takes into account [[shear deformation]] and [[rotary inertia]] was developed by Timoshenko in collaboration with [[Paul Ehrenfest]]. 
Thus it is referred to  as [[Timoshenko-Ehrenfest beam theory]]. This fact was testified by Timoshenko.<ref>Timoshenko, S. P. (1922) "On the transverse vibrations of bars of uniform cross-section", ''Philosophical Magazine'', page 125</ref> The interrelation between Timoshenko-Ehrenfest beam and [[Euler-Bernoulli beam theory]] was investigated in the book by Wang, Reddy and Lee.<ref>Wang, C.M., Reddy, J.N. and Lee, K.H.

He died in 1972 and his ashes are buried in [[Alta Mesa Memorial Park]], [[Palo Alto]], [[California]].
