ありがとう
フェラー氏の話は、「箱入り無数目」を議論していた2016年当時
有名なコテハンの”猫”氏が、それに言及していた

下記ですね
英語を苦にしないならば、原書を併読するのが良さそう（訳本は数式などに誤植が多いと言われるし、関係代名詞など日本語に訳しにくい部分が意訳になりがちなので）
（余談ですが、これにアクセスできる環境にないので、私はスルーですｗ）

William Feller
William "Vilim" Feller (July 7, 1906 – January 14, 1970), born Vilibald Srećko Feller, was a Croatian–American mathematician specializing in probability theory.

Feller was one of the greatest probabilists of the twentieth century. He is remembered for his championing of probability theory as a branch of mathematical analysis in Sweden and the United States.
In the middle of the 20th century, probability theory was popular in France and Russia, while mathematical statistics was more popular in the United Kingdom and the United States, according to the Swedish statistician, Harald Cramér.[7]
His two-volume textbook on probability theory and its applications was called "the most successful treatise on probability ever written" by Gian-Carlo Rota.[8] By stimulating his colleagues and students in Sweden and then in the United States, Feller helped establish research groups studying the analytic theory of probability.
In his research, Feller contributed to the study of the relationship between Markov chains and differential equations, where his theory of generators of one-parameter semigroups of stochastic processes gave rise to the theory of "Feller operators".
