Biography

Chung was a native of

Zhejiang Province. Chung entered Tsinghua University in 1936, and initially studied physics at its Department of Physics. In 1940, Chung graduated from the Department of Mathematics of the National Southwestern Associated University, where he later worked as a teaching assistant.[citation needed] During this period, he first studied number theory with Lo-Keng Hua and then probability theory with Pao-Lu Hsu
.

In 1944, Chung was chosen to be one of the recipients of the 6th

In 1950s, Chung taught at the

UC-Berkeley, Cornell University and Syracuse University. He then transferred to Stanford University in 1961, where he made fundamental contributions to the study of Brownian motion and laid the framework for the general mathematical theory of Markov chains
. Chung was later appointed Professor Emeritus of Mathematics of the Department of Mathematics at Stanford.

Chung was regarded as one of the leading probabilists after World War II. He was an Invited Speaker at the ICM in 1958 in Edinburgh and in 1970 in Nice. Some of his most influential contributions have been in the form of his expositions in his textbooks on elementary probability and Markov chains. In addition, Chung also explored other branches of mathematics, such as probabilistic potential theory and gauge theorems for the Schrödinger equation.

Chung's visit to China in 1979 (together with Joseph L. Doob and Jacques Neveu), and his subsequent visits, served as points of renewed exchange between Chinese probabilists and their Western counterparts. He also served as an external examiner for several universities in the Asian region, including the National University of Singapore.

In 1981, with

Erhan Cinlar and Ronald Getoor
, Chung initiated the "Seminars on Stochastic Processes", a popular annual national meeting covering Markov processes, Brownian motion and probability.

Chung possessed a wide-ranging and intimate knowledge of literature and music, especially opera. He also had an interest in Italian culture and taught himself Italian after he retired. He spoke several languages and translated a probability book from Russian to English.

Chung died of natural causes on June 1, 2009, at the age of 91.
