MEMORIAL RESOLUTION STEPHEN P.TIMOSHENKO (1878-1972) Professor Emeritus Stephen P.Timoshenko,world-renowned authority on theoretical and applied mechanics,died,on May 29,1972 at the age of ninety-three. Throughout his long and productive life,Timoshenko enjoyed excellent health and seemed always to be in high spirits.His refreshing interest in life continued unabated into his last years,and the end came somewhat suddenly after,a short illness from a kidney ailment.He died in his daughter's home in Wuppertal,Germany,where he had been living since 1964.Prior to that time,he had lived for many years in his own home on West Crescent Drive in Palo Alto. Timoshenko's accomplishments in the field of applied mechanics and his impact on engineering education in the United States were truly remarkable.His widespread influence as a teacher and writer has resulted in frequent references to him as "the father of applied mechanics"in this country,and his active years are often referred to as "the Timoshenko era"'in applied mechanics.At Stanford he assembled an internationally famous faculty that served as a magnet to students and scholars who came from all over the country and the world. Timoshenko personally directed many doctoral graduates who have themselves become outstanding as teachers,researchers,authors,and practicing engineers.The list of his former pupils reads like a Who's-Who in engineering mechanics.These persons continue to spread his philosophies and uphold his high standards.He admonished his students not to make their dissertations their last scientific effort but to be constantly alert to new developments.His students were always fascinated by his classroom lectures, which were inspiring and long remembered.His subject matter was so much a part of him that his classes were alive with interest,even when the topic was an old and classical one.Because of his intimate knowledge of the history of mechanics,he could teach the classical subjects through the medium of their creators,thus bringing a human dimension to a topic that in lesser hands might have been dull. It probably was through his widely-used textbooks that Timoshenko had his greatest influence.He was the author of thirteen popular textbooks in the field of mechanics,ranging from books for the first undergraduate course to books for advanced graduate students and research workers.These books have been used by hundreds of thousands of engineering students throughout the United States and the world,and they have been revised and updated through numerous editions.All of them have been published in several languages,and one book alone (Engineering Mechanics)has been translated into over ten languages. His best-known textbook is Strength of Materials,first published in Russia in 1911 and followed by several later Prussian editions.The first English version of this book was published in the United States in 1930 and achieved tremendous success.ItMEMORIAL RESOLUTION STEPHEN P.
