Prof. W. Z. Chien was born on 9 October, 1912 and 1982 saw the 70th
anniversary of his birth. Some of his friends, colleagues, and former
students prepared this special volume in honour of his outstanding
contribution to the field of mechanics. The volume does not contain
contributions from all of his students and friends and for this we
apologize. Prof. Chien's family have lived. in Qufangquiao Village,
Hongshengli, Wuxi County, Jiangsu Province for generations. Many members
of his family have been teachers in this village. When he was 14 years
old his father died and for a time it appeared necessary to terminate
his education but, fortunately, an uncle, Chien Mu, who later became a
very famous historian in China, came to his aid and he was able to
continue his studies. In 1931 he took entrance exams and was
simultaneously admitted to five prestigious Chinese universities. Of
these, he chose to enter Tsing-hau University in Beijing, with major
work in physics. He received his baccaulaurate in 1935 and taught at
middle school for a time until he was awarded a Sino: 'British
scholarship to study abroad. In the competition for this award, three of
the recipients were in the field of mechanics: Prof. C. C. Lin, Prof.
Kuo Yung-huai, and Prof. Chien Wei-zang. All three arrived in Toronto in
August, 1940 and entered the Depart- ment of Applied Mathematics of the
University of Toronto to study under Prof. J. L. Synge.
