Timoshenko's classic text on vibrations. (Printed on archival quality paper.) Timoshenko was a Ukrainian-American engineer and a pioneer in the study of the the vibrations of beams and other structures.
Stephen Timoshenko is the world-renowned authority in the field of mechanical engineering, and a prize named after him commemorates his contributions as author and teacher. The Timoshenko Medal is given annually for distinguished contributions in applied mechanics. As the father of modern engineering mechanics, Timoshenko wrote many of the essential early works in engineering mechanics, elasticity and strength of materials. Many of them are still in wide use. He wrote many textbooks on the subject, of which Vibration Problems in Engineering is one of his masterpieces.
