magacious writes "March 10 is the 133rd anniversary of the first telephone call. It occurred between Alexander Graham Bell and his assistant Thomas Watson back on this day in 1876. But there is some debate about whether Bell is actually the rightful owner of the crown for such invention. Having worked on the idea of transmitting speech using electricity for some time, Bell filed his patent on 14 February 1876, either just before or just after his main rival for the title of inventor of the telephone, Elisha Gray, filed his own. Bell won the patent and Gray died in obscurity."
