  Let $\Theta$ denote the supremum of the real parts of the zeros of the
Riemann zeta function. We demonstrate that $\Theta=1$, which entails the
existence of infinitely many Riemann zeros off the critical line (thus
disproving the Riemann Hypothesis (RH), which asserts that $\Theta =
\frac{1}{2}$). The paper is concluded by a brief discussion of why our argument
doesn't work for both Weil and Beurling zeta functions whose analogues of the
RH are known to be true.
