The Real Inventor Of The Telephone - Antonio Meucci
"Meucci wrote up all these findings in 1849... when Alexander Graham Bell was just 2 years old. Living in Havana at the time, Meucci conceived of the first telephonic system. He imagined that American industry would allow infinite production of his new technology. A telephonic system would revolutionize any nation which engineered its proliferation.
Meucci's priority for this scheme can be proved by the following: No mention of side-tone effects, nor measures to counteract it, are found in Bell's patents, nor in Gray's caveat, both of 1876. In the first Bell's subscriber lines, the four (initially, two) instruments were simply put in series on the same line. The first anti-sidetone (AST) circuits were introduced by the Bell people in the 1900s, particularly by George A. Campbell, with his nine patents of 1918, many decades after Meucci's solution was shown in this drawing, and over thirty years after the same drawing was notarized.
Meucci's experiments, both in Havana and Clifton, on the electrical transmission of the human voice, are basically substantiated by Meucci's own testimony at the Bell/Globe trial of 1885-1886 and by some fifty affidavits, sworn by various witnesses between 1880 and 1885. In addition, his electromagnetic telephone was described in L'Eco d'Italia of New York at the beginning of 1861, though all issues of the 1861-1863 period are not available in the major libraries of the United States. Havana's experiments were briefly mentioned in a letter by Meucci, published by Il Commercio di Genova of 1 December 1865 and by "L'Eco d'Italia" of 21 October 1865 (both existing today). Finally, a caveat (or preliminary patent) titled Sound Telegraph, setting forth the basic principles of Meucci's telephonic system, was filed with the US Patent Office on 28 December 1871, five years before the first Bell patent, and its validity was extended up to December 1874, by paying the corresponding fees.

HUI/XAU/gold's multi month trendline broke down three weeks ago, which is obviously a major technical breakdown, not to mention that it's probably the start of an 18 monthish Wave 2 Cyclical Bear Market.
Most gold writers are providing advice that will cause investors and traders to catch a falling knife. Long term it will be tend to be disastrous for investors, since it'll take years in most cases for them to get back to break even, if they ever do get back to break even.
