Where can I find Rademacher's wrong disproof of the Riemann Hypothesis? Mathematical folklore has it that the famous algebraist Hans Rademacher once came up with a wrong disproof of the Riemann Hypothesis, which was initially believed by another famous mathematician, Carl Siegel. I vaguely remember that they say Rademacher's error was that he mistakenly assumed that logarithms of complex numbers are uni-valued. 
But where can I find this particular work of Rademacher? 
I would want to go over it in detail and I imagine something could be learned from it. A Google search didn't yield anything meaningful.
 A: This does not directly answer the question, but gives the details of the story, including the source of the error.

A sure way for any mathematician to achieve immortal fame would be to
  prove or disprove the Riemann hypothesis. This baffling theory, which
  deals with prime numbers, is usually stated in Riemann's symbolism as
  follows: "All the nontrivial zeros of the zeta function of s, a
  complex variable, lie on the line where $\sigma$ is ½ -- ($\sigma$
  being the real part of s)." The theory was propounded in 1859 by
  Georg Friedrich Bernhard Riemann (who revolutionized geometry and laid
  the foundations for Einstein's theory of relativity). No layman has
  ever been able to understand it and no mathematician has ever proved
  it.
One day last month electrifying news arrived at the University of
  Chicago office of Dr. Adrian A. Albert, editor of the Transactions of
  the American Mathematical Society. A wire from the society's
  secretary, University of Pennsylvania Professor John R. Kline, asked
  Editor Albert to stop the presses: a paper disproving the Riemann
  hypothesis was on the way. Its author: Professor Hans Adolf
  Rademacher, a refugee German mathematician now at Penn.
On the heels of the telegram came a letter from Professor Rademacher
  himself, reporting that his calculations had been checked and
  confirmed by famed Mathematician Carl Siegel of Princeton's Institute
  for Advanced Study. Editor Albert got ready to publish the historic
  paper in the May issue. U.S. mathematicians, hearing the wildfire
  rumor, held their breath. Alas for drama, last week the issue went to
  press without the Rademacher article. At the last moment the professor
  wired meekly that it was all a mistake; on rechecking. Mathematician
  Siegel had discovered a flaw (undisclosed) in the Rademacher
  reasoning. U.S. mathematicians felt much like the morning after a
  phony armistice celebration. Sighed Editor Albert: ''The whole thing
  certainly raised a lot of false hopes."

The "undisclosed" flaw found by Siegel is identified on page 109 of The Riemann Hypothesis: The Greatest Unsolved Problem in Mathematics:
