If your Kitchen is small and the supply orders are too much. Get ready for a production line batch!

In the first years of  1900 the U.S. military armed forces requested a great innovation and technology in the field of the radio communications.  Nathaniel Baldwin, an electrical engineer from the state of  UTAH (USA) and graduated from the University of Stanford, he experimented with sound amplification using compressed air, while he was working as electrician andair compressor operator.

He used this intuition for designing and testing a more profitable device in the 1910: the headphones. The main customer for this product was the U.S. Navy and the history tells that Lt. Comdr. A. J. Hepburn received for prototype for a pair of telephones fashioned into a headset, along with a letter from Nathaniel Baldwin written with purple ink on blue and pink paper. After initially disregarding the message, Hepburn tested the device and found that it worked surprisingly well to transmit sound.  The Navy began to ask for more headphones from Baldwin, who could only accept batch orders of 10 at a time because he was producing them alone in his kitchen.

In 1914, Baldwin started a business in East Millcreek, Utah (USA) called The Baldwin Radio Company . He powered the plant and the neighborhood through a hydroelectric generator which he made out of bicycle wheels and piano wire. The company peaked at 150 employees and $2 million in annual sales in the 1920s. Unfortunately Unwise investments led to Baldwin’s company’s bankruptcy in 1924. Today his invention is one the most useful in the world in different fields such as: music, computer science, gaming and so on.
