On May 10th, 1876, Alexander Graham Bell said the famous words: "Mr. Watson, come here. I want you" after spilling some sulphuric acid on his shirt. These words made history as it was the first articulate sentence spoken over an electric telephone. The transmitter was also an example of "The Great Patent Race" as Graham's model and patent were very similar to another patent filled by Elisha Gray on the same day.The transmitter worked by using a series of cones, needles, wires, and batteries to turn sound waves into an electric signal that was then carried through a wire to the receiver in another room.
