  • First long distance television transmission

    First long distance television transmission
    Bell labs makes the first long distance television transmission by sending live images of Herbert Hoover over telephone lines from Washington Dc to New York City.
  • First Bimary Digital computer

    First Bimary Digital computer
    Bell labs introduced the complex number calculator, which was the first binary computer, which means it was doing its operations in binary form. This computer could find the quotient of two eight digit numbers in 30 seconds
  • Long distance computing

    Long distance computing
    Bell lab's demonstrated the first long distance operation of a computer during 1940. The demonstration connected a teletypewriter in New Hampshire with a computer in Bell labs in New York City.
  • First Mobile Telephone Call

    First Mobile Telephone Call
    A truck driver from St. louis made the fist ever mobile telephone call from a new mobile phone that was built into the trucks dashboard
  • The Transistor

    The Transistor
    In 1947, Bell labs scientists John Bardeen and Walter Brattian invented the transistor. They would later recieve a nobel prize in physics for their findings
  • Direct Distance Calling

    Direct Distance Calling
    Bell labs introduced direct distance calling early in 1951, this allowed customers to make long distance calls in the US without having to use and operator for assistance
  • Solar Cells

    Solar Cells
    Three researchers, Gerald Pearson, Calvin Fuller and Daryl Chapin used a diffused sillicon junction and created a solar cell that was capable of six percent enegry conversion rate in sunlight
  • First Infared laser

    First Infared laser
    Bell labs scientists Charles Hard Townes and Arthur Leonard Schawlow created the first laster in 1958 created the first infared laser. At the time they called thie invention an "optical maser"
