Markov processes in continuous time were discovered long before Andrey Markov's work in the early 20th . centuryin. the form of the Poisson process.. Markov was interested in studying an extension of independent random sequences, motivated by a disagreement with Pavel Nekrasov who claimed independence was necessary for the weak law of large numbers to hold..
