Andrey Markov
The Russian mathematician who, in 1913, stripped Pushkin’s Eugene Onegin to a ribbon of vowels and consonants to win an argument about free will, and in doing so produced the first statistical analysis of language and the foundational structure from which every language model, every PageRank algorithm, and every next-token prediction descends.
Andrey Markov did not invent the language model. He invented something stranger and, in the end, more powerful: a proof that statistical regularity implies nothing about what lies beneath it, built from the observation that dependent events can produce the same stable averages as independent ones. He built this proof by counting vowels in Russia’s most beloved poem, not because he loved poetry but because he needed to win a mathematical argument about the soul. His weapon in that fight—the
Markov chain, a sequence in which the future depends only on the present—became the mathematical ancestor of every system that now completes your sentence. The direct line from his grids of Cyrillic letters runs through Claude Shannon’s information theory, through the n-gram models of speech recognition, through Google’s PageRank algorithm, and into the transformer architectures of
large language models: all are machines
