Thomas Edison invented the phonograph in 1877, which was the first device capable of recording and playing back the human voice. The Ediphone and Dictaphone, introduced between 1878-1916, improved on the phonograph by using paraffin-coated cylinders that could be erased and reused. Emile Berliner invented the Gramophone in 1888, which used flat discs instead of cylinders to record sound. Valdemar Poulsen invented the Telegraphone in 1898, the first device to use magnetism to record sound on a wire. In 1935, Willy Müller invented the first automatic answering machine.

2. Phonograph 1877 On December 4th 1877, Thomas Edison was the first person to ever record and play back the human voice. Developments that Edison made to telegraphs and telephones led to the invention of the phonograph. A band of tin foil was mounted on a cylinder, and the cylinder was turned by a hand crank during the recording and the playback. Edison turned the crank and spoke the first recorded words. "Mary had a little lamb, its fleece was white as snow, and everywhere that Mary went, the lamb was sure to go."

3. Ediphone and Dictaphone 1878 - 1916 The name "Dictaphone" trademark was originally registered by the Columbia Gramophone Company in 1907. Dictaphone was spun off into a separate company in 1923 and continued manufacturing wax cylinder dictating equipment up until 1947 when it introduced the Dictabelt, which subsequently replaced the old wax cylinder technology. The Dictaphone and Ediphone were for practical purposes, almost identical products. Edison initially sold his phonographs intended for business dictating use under the phonograph name. This led to product line confusion and Edison finally renamed his phonograph line intended for business dictation to the Ediphone in 1916. they were both similar to the original phonograph but the main improvement was the paraffin coated cylinders. The advantage of the paraffin coated cylinders was that it was capable of erasing and being re-used again. This was the first device that allowed for erasure in recording. Early Cylinders could only record up to about 2 minutes of dictation. Larger cylinders combined with a smaller track pitch, increased recording times 4 fold to about 8 to 9 minutes per cylinder.

4. Gramophone 1888 As the phonograph was being developed, a German immigrant called Emile Berliner took an interest in recording technology. In 1888 he filed and patented a talking machine which also recorded and played back sound. Instead of using a cylinder, Berliner used a flat recording disc and a stylus which cut a spiral groove while the stylus in the cylinder moved up and down in vertical cut recording format to record the actual audio. Berliner called his invention, the Gramophone. The main advantage of using a flat medium disc is that thousands of records could be inexpensively pressed from one master.

5. Telegraphone 1898 ValdemarPoulsen was a Danish telephone engineer and inventor who also patented what he called a telegraphone. The telegraphone was the first practical apparatus for recording magnetic sound. It recorded telephone conversations. It recorded, on a wire, the varying magnetic fields produced by a sound. The magnetized wire could then be used to play back the sound. This was invented by the

6. First Automatic Answering Machine Mr. Willy Müller invented the first automatic answering machine in 1935. It was a three foot tall machine.
