Eiffel is an object-oriented programming language designed by Bertrand Meyer (an object-orientation proponent and author of Object-Oriented Software Construction) and Eiffel Software. Meyer conceived the language in 1985 with the goal of increasing the reliability of commercial software development;[4] the first version becoming available in 1986. In 2005, Eiffel became an ISO-standardized language.
The design of the language is closely connected with the Eiffel programming method. Both are based on a set of principles, including design by contract, command–query separation, the uniform-access principle, the single-choice principle, the open–closed principle, and option–operand separation.
Many concepts initially introduced by Eiffel later found their way into Java, C#, and other languages. [5] New language design ideas, particularly through the Ecma/ISO standardization process, continue to be incorporated into the Eiffel language.

To a lesser extent, Python, LISP, Eiffel, Ada, and C++ have also influenced Ruby.
