OO and Eiffel
Eiffel was designed at ISE in 1985 by Bertrand Meyer. Eiffel attracted considerable attention and ISE released it as a commercial product at the end of 1986.
Eiffel is used in many application areas including telecommunications.
The main influences on the design have been the object oriented concepts introduced by Simula 67 and the Algol 60/Algol W/Pascal/Ada line of programming languages.
