Victor Bunakov

Viktor Yakovlevich Bunyakovsky (Russian: Виктор Яковлевич Буняковский; Ukrainian: Віктор Якович Буняковський, romanized: Viktor Yakovych Buniakovskyi; 16 December [O.S. 4 December] 1804 – 12 December [O.S. 30 November] 1889) was a Russian mathematician, member and later vice president of the Petersburg Academy of Sciences.
Bunyakovsky was a mathematician, noted for his work in theoretical mechanics and number theory (see: Bunyakovsky conjecture), and is credited with an early discovery of the Cauchy–Schwarz inequality, proving it for the infinite dimensional case as well as for definite integrals of real-valued functions in 1859, many years prior to Hermann Schwarz's works on the subject.
