Question: Which mathematician was born first, Pyotr Novikov or Dmitri Egorov?
Context: Yurii (or Yuri) Vladimirovich Egorov (Юрий Владимирович Егоров, born 14 July 1938 in Moscow) is a Russian-Soviet mathematician who specializes in differential equations. Pyotr Sergeyevich Novikov (Russian: Пётр Серге́евич Но́виков ; 15 August 1901, Moscow, Russian Empire – 9 January 1975, Moscow, Soviet Union) was a Soviet mathematician. "Lab Rats", also known as "Lab Rats: Bionic Island" for its fourth season, is an American television sitcom that premiered on February 27, 2012, on Disney XD.  It focuses on the life of teenager Leo Dooley, whose mother, Tasha, marries billionaire genius Donald Davenport.  He meets Adam, Bree, and Chase, three bionic superhumans, with whom he develops an immediate friendship.  It should be noted that the names of the Lab Rats imply that they were originally known as subjects A, B, C and D. Adam was born first, then Bree, then Chase, and finally Daniel. Dmitri Fyodorovich Egorov (Russian: Дми́трий Фёдорович Его́ров ; December 22, 1869 – September 10, 1931) was a Russian and Soviet mathematician known for significant contributions to the areas of differential geometry and mathematical analysis.  He was President of the Moscow Mathematical Society (1923 — 1930). Matematicheskii Sbornik (Russian: Математический сборник , abbreviated "Mat.  Sb.")  is a peer reviewed Russian mathematical journal founded by the Moscow Mathematical Society in 1866.  It is the oldest successful Russian mathematical journal.  The English translation is "Sbornik: Mathematics".  It is also sometimes cited under the alternative name "Izdavaemyi Moskovskim Matematicheskim Obshchestvom" or its French translation "Recueil mathématique de la Société mathématique de Moscou", but the name "Recueil mathématique" is also used for an unrelated journal, "Mathesis".  Yet another name, "Sovetskii Matematiceskii Sbornik", was listed in a statement in the journal in 1931 apologizing for the former editorship of Dmitri Egorov, who had been recently discredited for his religious views; however, this name was never actually used by the journal. Carlo Severini (10 March 1872 – 11 May 1951) was an Italian mathematician: he was born in Arcevia (Province of Ancona) and died in Pesaro.  Severini, independently from Dmitri Fyodorovich Egorov, proved and published earlier a proof of the theorem now known as Egorov's theorem. In measure theory, an area of mathematics, Egorov's theorem establishes a condition for the uniform convergence of a pointwise convergent sequence of measurable functions.  It is also named Severini–Egoroff theorem or Severini–Egorov theorem, after Carlo Severini, an Italian mathematician, and Dmitri Egorov, a Russian physicist and geometer, who published independent proofs respectively in 1910 and 1911. In Greek mythology, Despoina, Despoena or Despoine, was the daughter of Demeter and Poseidon and sister of Arion.  She was the goddess of mysteries of Arcadian cults worshipped under the title "Despoina", "the mistress" alongside her mother Demeter, one of the goddesses of the Eleusinian mysteries.  Her real name could not be revealed to anyone except those initiated to her mysteries.  Pausanias spoke of Demeter as having two daughters; Kore being born first, then later Despoina.  With Zeus being the father of Kore, and Poseidon as the father of Despoina.  Pausanias made it clear that Kore is Persephone, though he wouldn't reveal Despoina's proper name. Augustine of Canterbury (born first third of the 6th century – died probably 26 May 604) was a Catholic Benedictine monk who became the first Archbishop of Canterbury in the year 597.  He is considered the "Apostle to the English" and a founder of the Catholic Church in England.
