[QUOTE="spiney, post: 226560, member: 192438"] Yes, Dove, how true! There's a book (I've a copy) called "The telephone and its several inventors", which mentions Gray, and many others ....... With all these inventions, there were originally several competing commercial systems. For example, with early radio there was Marconi, Fessenden, Slaby-Arco, Popov (often forgotten!), etc ..... (also not forgetting the British Lodge-Muirhead system, Marconi later had to pay Lodge back-roaylties for using his patented tuning system, without first asking ......) PS, I don't think you could really call Tesla an "early radio" man. What his Tower was supposed to do was transmit a huge induction field all round the world (exactly how it would have "stopped wars" remains a mystery!). If completed, what he'd actually have been doing is transmit VLF - or maybe LF - via a "Fessenden style" (possibly an Alexanderson) high frequency alternator. PPS, yes, I seem to recall Tesla was a quiet solitary person, but it's a few years since I read his biography. (Tesla liked feeding pigeons! If you see Mel Brooks' original "The Producers" film, the writer character in the tin helmet who keeps pigeons is supposedly partly based on Tesla. I haven't seen the more recent musical version, is he still in that?). PPPS, yes, Marconi's 1st transatlantic transmission, very interesting! Both he and his assistant claimed they heard the (pre-arranged!) Morse Code signal, but there was only their word for it! I believe the IEEE have recently carried out some experiments, and concluded that it WOULD have been possible for Marconi to receive the transmission using the equipment he had. But, as to whether he really did ....... PPPPS, Bell is yet another inventor who eventually went mad! Towards the end of his life - with worldwide telephone/cable/radio communications by then well established - Bell still maintained that his greatest ever invention was ....... The Photophone!
