Can you please give me atleast 5 persons contributed in the development of computer programming?

And their contributions please...

Can you please give me atleast 5 persons contributed in the development of computer programming?
Charles Babbage - invention of difference machine in 1822.





Herman Hollerith - in 1896 founded the Tabulating Machine Company (which became IBM). He invented the Hollerith punched card, the card reader, and the key punch machine.





John Von Neumann (1945)- developed two important concepts that directly affected the path of computer programming languages.


1. "shared-program technique". This technique stated that the actual computer hardware should be simple and not need to be hand-wired for each program. Instead, complex instructions should be used to control the simple hardware, allowing it to be reprogrammed much faster.


2. "conditional control transfer".This idea gave rise to the notion of subroutines, or small blocks of code that could be jumped to in any order, instead of a single set of chronologically ordered steps for the computer to take.





Grace Hopper- wrote the first compiler, A-0 in 1951A compiler is a program that turns the language's statements into 0's and 1's for the computer to understand. This lead to faster programming, as the programmer no longer had to do the work by hand.





John McCarthy of MIT- created the LISt Processing (or LISP) language. It was designed for Artificial Intelligence (AI) research in 1958.





Niklaus Wirth- began developing Pascal in 1968.
