In the predawn hours of May Day, two professors at Dartmouth College run the first program in their new language, Basic. Mathematicians John G. Kemeny and Thomas E. Kurtz had been trying to make computing more accessible to their undergraduate students. One problem was that available computing languages like Fortran and Algol were so complex that you really had to be a professional to use them.
So the two professors started writing easy-to-use programming languages in 1956. First came Dartmouth Simplified Code, or Darsimco. Next was the Dartmouth Oversimplified Programming Experiment, or Dope, which was too simple to be of much use. But Kemeny and Kurtz used what they learned to craft the Beginner's All-Purpose Symbolic Instruction Code, or Basic, starting in 1963.
The other problem Kemeny and Kurtz attacked was batch-processing, which made for long waits between the successive runs of a debugging process. Building on work by Fernando Corbató, they completed the Dartmouth Time Sharing System, or DTSS, later in 1964. Like Basic, it revolutionized computing.
