Upon returning to his native Russia in the summer of 1906, Stephen Timoshenko embarked on a transformative phase of his career and life. He was appointed to the Chair of Strength of Materials at the Kiev Polytechnic Institute in Ukraine, marking the beginning of a tenure that would have a profound impact on both his professional trajectory and personal life. This period in Ukraine was not just a return to his roots but a pivotal moment that shaped his future contributions to engineering and academia.

Despite the backdrop of political unrest and challenges to academic freedom, which ultimately led to his dismissal in 1911, Timoshenko's scientific and educational endeavors thrived. He developed and refined innovative teaching methodologies, emphasizing the gradual introduction of complex analytical methods from simple concepts. This pedagogical approach not only enhanced the learning experience for his students but also laid the foundation for future advancements in engineering education.

During these formative years from 1907 to 1911, Timoshenko's research contributions were groundbreaking. He conducted pioneering work on what would later be recognized as early variants of the Finite Element Method for elastic calculations, also known as the Rayleigh method. His work on buckling became a cornerstone of structural engineering, pushing the boundaries of the field and setting new standards for research and application.

In 1909, Timoshenko's influence within the academic community was further solidified when he was elected dean of the Division of Structural Engineering. This role, however, brought with it administrative responsibilities that he felt detracted from his own research work, a sentiment that highlights his deep commitment to scientific inquiry and education.

The publication of the first version of his Strength of Materials textbook in 1911, along with receiving the prestigious Zhuravski Medal, were significant milestones that underscored Timoshenko's achievements during this tumultuous yet productive period. These accomplishments not only marked a high point in his career but also contributed to his lasting legacy in the field of engineering.

The period from 1911 to the early 1920s was a tumultuous but profoundly productive time in the life of Stephen P. Timoshenko, marked by significant professional advancements, personal challenges, and the backdrop of world-changing events. In 1911, after signing a protest against the Minister of Education Kasso, Timoshenko faced dismissal from the Kiev Polytechnic Institute. Ironically, this setback coincided with his receipt of the D. I. Zhuravski prize from the St. Petersburg State Transport University, a recognition that provided financial support during a pivotal time in his career.

Following his departure from Kiev, Timoshenko returned to St. Petersburg, where he secured part-time teaching positions and continued his writing. His academic pursuits were briefly interrupted in 1912 when he and his wife traveled to England, using the funds from the Zhuravski Prize. There, Timoshenko attended a mathematical congress in Cambridge, meeting luminaries such as Lord Rayleigh, A. E. H. Love, and Horace Lamb. Despite facing language barriers, this experience enriched his academic perspective and broadened his professional network.

By the fall of 1912, Timoshenko had resumed his teaching roles in St. Petersburg and was invited to take over theoretical mechanics duties at the Ways of Communication Institute from Professor Krylov. His work during this period expanded to include consulting on applications of elastic stability to ship bulkheads for the Naval Ministry. Despite these professional successes, the living conditions in St. Petersburg were challenging, and Timoshenko's health suffered.

The outbreak of World War I in 1914 marked a significant shift in Timoshenko's life and work. He intensified his consulting efforts, focusing on shipbuilding and railroad transportation issues critical to the war effort. The war and subsequent Russian Revolution dramatically worsened living conditions and led to the disintegration of the Russian social structure. Timoshenko's response to these upheavals was to send his family to the relative safety of the Crimea, with plans to later join them.

In 1918, amid the chaos of the Russian Civil War, Timoshenko returned to Kiev, where he played a pivotal role in establishing the Ukrainian Academy of Sciences alongside Vladimir Vernadsky. This period also saw him leading the Institute of Mechanics of the Ukrainian Academy of Sciences, a testament to his enduring influence on the field.

However, the advance of the Armed Forces of South Russia led by General Denikin into Kiev in 1919 forced Timoshenko to leave his homeland once again. This decision marked the end of his chapter in Russia and Ukraine. He traveled through Novorossiysk, Crimea, and Constantinople (present-day Istanbul) to Yugoslavia, continuing his work in a new environment.

Throughout these years, Timoshenko's contributions to the fields of elasticity, beam deflection, and buckling continued to evolve. He laid the foundational theories that would become cornerstones of mechanical engineering. Despite the personal and professional upheavals he experienced, Timoshenko's legacy was cemented through his resilience, innovative research, and profound impact on engineering education and practice. This era of his life reflects a bridge between his early achievements in Russia and Ukraine and his future contributions on the international stage, demonstrating his unwavering commitment to advancing engineering knowledge amidst the most challenging circumstances.

Timoshenko's Repair of the Czar's Winter Palace

Stephen Timoshenko's son, Gregory, mentions the repair work that his father had done at the Czar's Winter Palace. This assignment showed that the Czar's people were aware, and appreciative of Timoshenko's skills. Such "tolerance" by the Russian government was a welcome sign, especially after Timoshenko's dismissal in Kiev for taking a stand for progress against a backward-looking education bureaucracy. Gregory's account is as follows:

Kiev to St. Petersburg (1910-1914)

"Because of student political disruptions at the Institute in Kiev, Dad and two other Deans were dismissed by the Czar’s government (by an unpopular minister) from their jobs. Ten of the best professors resigned from their jobs in solidarity. You cannot expect such (loyalty) from a faculty in the U.S.A. We moved to St. Petersburg, where, for several months, we ate primarily homemade hash and browned potatoes. It is still one of my favorites, though I won’t eat it in a restaurant or out of a can.

"Ironically, at the time Dad lost his job, he was awarded the Zhuravskii Gold Medal for the best technical work - in Russia. Thus, the scientific groups acted quite independently of pressure attempts by the government. After a few years of such “semi-exile”, Dad was again a full professor at several Universities, and we moved to the faculty apartments at the College of Electrical Engineering.

"A little later, a crack developed in the ceiling of one of the rooms in the Czar’s Winter Palace. Dad was called in as the top expert to advise on its repair, and then all was OK. The Czar’s people were pleased with this work. Thus, despite all, the government had some sense and was moderately tolerant."
