Timoshenko's field was really applied mechanics, and his publications are
aimed toward strength of materials and structural dynamics. The rest of
the following exerpt is at
http://ece.clemson.edu/crb/misc/scientists/timoshenko.htm. I think I read
someplace where he left Russia during the Civil War with the Red Army in
hot pursuit. The story sounded very exciting.
STEPHEN P. TIMOSHENKO was born in 1878 in Russia. His father Timofeyevich
was a surveyor and his mother was a voracious reader. During his early
childhood, Timoshenko enjoyed playing in piles of sand near building
construction sites - he built fortresses, castles and especially rail
roads. When he was five years old his schooling started. Timoshenko never
liked his class room studies and at home he worked with pleasure. He felt
sitting five hours every day in a class room is a waste of time. He
always pushed himself forward or to display his knowledge to the teacher.
Timoshenko studied mathematics with pleasure and solved various problems
for amusement and not because they were assigned. When he was promoted to
grade four, Timoshenko learnt how to operate a harvesting machine. At the
age of 14 he learnt to sketch and draw, and participated in planning and
building a house. At the age of 18 he joined an institute at the Ministry
of Ways of Communication in St.Petersburg. During the summers of 1899 and
1900 Timoshenko spent practicing on construction of Volchansk- Kupyansk
rail road so that he could learn all the important types of construction.
His student years coincided with the start of political quickening in
Russia manifested primarily in student disturbances. In the summer of
1900, the international exposition opened in Paris and he went as a
student who knew foreign language to serve at the ways of communications
exhibit. With 200 roubles and a free ticket Timoshenko set out from
Petersburg for Paris. This was his first trip abroad.
Upon graduation from the institute, Timoshenko was faced with a year of
compulsory military service at the time when most of the youths opposed
military service. Military service not only afforded him an opportunity
to become better acquainted with low class people but gymnastics and
living in a tent in summer improved his physical health.
After military service Timoshenko got married to Aledxandra
Archangleskya in 1902 who was a medical student. At that time he worked
at the mechanics laboratory with a salary of 100 roubles a month. He
became well acquainted with testing machines and soon saw that apart from
learning the techniques of mechanical testing of building materials he
could accomplish nothing at the laboratory. Timoshenko felt that for a
scientific work a more thorough grounding in mathematics and mechanics
was needed and he tried to use every opportunity available at the
institute to expand his education. Then he joined The Petersburg
Polytechnic in 1903. In 1904 he travelled to Europe with a specific
purpose of becoming better acquainted with German technical school and
their teaching methods. Timoshenko took interest in reading Rayleigh's
book The Theory of Sound and he was particularly captivated by the
approximate methods of calculating vibration frequencies of complex
structures. In 1907-1908 he gave a full course on Strength of materials
and later on published in lithographic form.
