, was appointed Assistant Professor in 1953 and continued working there beyond his retirement in 1991 until his death.

Le Cam was the major figure during the period 1950 – 1990 in the development of abstract general asymptotic theory in mathematical statistics. He is best known for the general concepts of local asymptotic normality
Local asymptotic normality
In statistics, local asymptotic normality is a property of a sequence of statistical models, which allows this sequence to be asymptotically approximated by a normal location model, after a rescaling of the parameter...

Contiguity (probability theory)
In probability theory, two sequences of probability measures are said to be contiguous if asymptotically they share the same support. Thus the notion of contiguity extends the concept of absolute continuity to the sequences of measures....
