"Marvelous cancellations": T.J. Stieltjes' letters concerning the zeta   function
  This article introduces and translates letters from T.J. stieltjes (1856-1894) to C. Hermite (1822-1891) regarding Stieltjes' published notes claiming to have solved B. Riemann's conjecture "it is very probable that all the roots [of the zeta function] are real."
