First edition, journal issue. ""One of Lambert's most famous results is the proof of the irrationality of ""N"" and e. It was based on the continued fractions, and two such fractions still bear his name.""(DSB).""Euler's work on continued fractions was used by Johann Heinrich Lambert.....to prove that if x is a rational number (not 0), then ex and tan x cannot be rational. He thereby proved not only that ex for positive integral x is irrational, but that all rational numbers have irrational natural (base e) logarithms.From the result of tan x, it follows tha, since tan (n/4)= 1, that neither n/4 nor n can be rational.Lambert actually proved the convergencee ofthe continued fraction expansion for tan x.

First printing of the milestone paper in which Stieltjes introduced the ""Stieltjes Integral"". He is often called ""the father of the analytic theory of continued fractions"" for his work in this area. ""On 18 June 1894 he published Recherches sur les fractions continues in Comptes Rendus de l'Académie des Sciences. A fuller version of this work appeared in the Annales de la Faculté des Sciences de Toulouse."" The integral which he introduced here while solving the moment problem, that is, given the moments of all orders of a body, find the distribution of its mass."".... a mathematical milestone. The work represents the first general treatment of continued fractions as part of complex analytic function theory"" previously, only special cases had been considered.""
