#4 John George Kemeny and Thomas Eugene Kurtz

These two programmers were in charge back in the ’60s, in developing the BASIC programming. BASIC was the first high-level program to use simple language. It is an acronym from Beginner's All-purpose Symbolic Instruction Code.

At the time, nearly all use of computers required writing custom software, which was something only scientists and mathematicians tended to do. The presence of an easy-to-learn language such as BASIC on these early personal computers allowed small business owners to develop their own custom application software, leading to widespread use of these computers in businesses that previously did not have access to computing technology.

They also developed Dartmouth Time-Sharing System, or DTSS for short. It was the first large-scale time-sharing system to be implemented successfully.

In computing, time-sharing is the sharing of a computing resource among many users by means of multiprogramming and multi-tasking.
