Editing Andrey Markov (section)

== Biography ==
Andrey Markov was born on 14 June 1856 in Russia. He attended the St. Petersburg Grammar School, where some teachers saw him as a rebellious student. In his academics he performed poorly in most subjects other than mathematics.  Later in life he attended Saint Petersburg Imperial University (now [[Saint Petersburg State University]]). Among his teachers were [[Yulian Sokhotski]] (differential calculus, higher algebra), [[Konstantin Posse]] (analytic geometry), Yegor Zolotarev (integral calculus), [[Pafnuty Chebyshev]] (number theory and probability theory), [[Aleksandr Korkin]] (ordinary and partial differential equations), Mikhail Okatov (mechanism theory), [[Osip Somov]] (mechanics), and Nikolai Budajev (descriptive and higher geometry).  He completed his studies at the university and was later asked if he would like to stay and have a career as a mathematician. He later taught at high schools and continued his own mathematical studies. In this time he found a practical use for his mathematical skills. He figured out that he could use chains to model the alliteration of vowels and consonants in Russian literature. He also contributed to many other mathematical aspects in his time. He died at age 66 on 20 July 1922.
