Stepan Timoshenko
1878 – 1972
Father of modern engineering mechanics; wrote the textbooks a century used.
Often called the father of modern engineering mechanics, Timoshenko fled revolutionary Russia and reshaped how strength of materials and vibration are taught in the West. His textbooks trained several generations of engineers.
His beam and vibration theory sits behind the mechanical and structural calculators here. If you learned mechanics of materials from a textbook, its lineage very likely runs through Timoshenko.
