Hamburger Oklahoma in 1891, calling Tulsa, "The Real Birthplace of the Hamburger." Frank and Charles Menches claim to have sold a ground beef sandwich at the Erie County Fair in 1885 in Hamburg, New York. During the fair, they ran out of pork sausage for their sandwiches and substituted beef. Kunzog, who spoke to Frank Menches, says they exhausted their supply of sausage, so purchased chopped up beef from a butcher, Andrew Klein. Historian Joseph Streamer wrote that the meat was from Stein's market not Klein's, despite Stein's having sold the market in 1874. The story notes that the name of
Hamburger moment problem "Jacobi matrix representation". This in turn leads to a "tridiagonal model" of positive Hankel kernels. An explicit calculation of the Cayley transform of "T" shows the connection with what is called the "Nevanlinna class" of analytic functions on the left half plane. Passing to the non-commutative setting, this motivates "Krein's formula" which parametrizes the extensions of partial isometries. The cumulative distribution function and the probability density function can often be found by applying the inverse Laplace transform to the moment generating function provided that this function converges.
