Euler's Correspondence with Christian Goldbach

(1690-1764) became professor of mathematics and historian at St. Petersburg in 1725. He met Euler there, and when he (Goldbach) left St. Petersberg three years later as a tutor to the young Peter II, he and Euler maintained an active correspondence for 35 years. It was Goldbach who first whetted Euler's interest in number theory. In fact, what we refer to today as "Goldbach's Conjecture" (that every even integer is the sum of two primes), was first stated in a letter from Goldbach to Euler.
