COBOL emerged from a committee effort to make business programs readable and portable across competing computer manufacturers, creating one of computing's most durable language ecosystems.
BASIC was designed at Dartmouth alongside time-sharing so that students outside specialist computing courses could sit at a terminal and write programs themselves.
C emerged alongside Unix at Bell Labs and helped demonstrate that operating systems could be written in a high-level language without giving up close control of the machine.
Smalltalk joined an object-oriented language, a graphical environment and a vision of personal computing into one unusually integrated system at Xerox PARC.
C++ began as Bjarne Stroustrup's attempt to bring stronger abstraction to C while preserving the efficiency and systems access that made C valuable.
Python grew from Guido van Rossum's work at CWI into a language whose readability, interactive use and broad standard library made it unusually adaptable across domains.
Java evolved from Sun's Oak project into a language and virtual-machine platform built around portability, managed memory and networked software.
JavaScript transformed the browser from a document viewer into a programmable environment, then survived browser competition by becoming an independently standardized language.
LISP gave symbolic computation a language whose programs and data shared a common representation, reshaping artificial intelligence and the theory of programming.
FORTRAN did more than introduce convenient mathematical notation. Its compiler proved that a high-level language could produce code efficient enough for serious scientific work.
