In 1945, very early in the history of the development of a rigorous analytical theory of probability, Feller (1945) wrote a paper called The fundamental limit theorems in probability in which he set out what he considered to be the two most important limit theorems in the modern theory of probability: the central limit theorem and the recently discovered Kolmogoroffs cel­ ebrated law of the iterated logarithm . A little later in the article he added to these, via a charming description, the little brother (of the central limit theo­ rem), the weak law of large numbers, and also the strong law of large num­ bers, which he considers as a close relative of the law of the iterated logarithm. Feller might well have added to these also the beautiful and highly applicable results of renewal theory, which at the time he himself together with eminent colleagues were vigorously producing. Fellers introductory remarks include the visionary: The history of probability shows that our problems must be treated in their greatest generality: only in this way can we hope to discover the most natural tools and to open channels for new progress. This remark leads naturally to that characteristic of our theory which makes it attractive beyond its importance for various applications: a combination of an amazing generality with algebraic precision.
