> While SIMULA wasn’t the first “true” OOP language, it was the first language with proper objects and laid much of the groundwork that others would build on. This is wrong. Simula 67 was the first object-oriented programming language; though the term is said to be coined by Alan Kay who specified Smalltalk-72; but he understood and still understands object-orientation differently than we understand it today; our understanding of it today is more like what Simula 67 introduced; remarkably, Smalltalk-76 represented a significant departure from Smalltalk-72 toward the concepts already known in Simula 67; the primary difference of Smalltalk 76 from Simula was dynamic typing and the conception of even simple types as classes. Simula 67 was still actively used in the nineties (e.g. as a teaching language at Stockholm University until 1997). The performance was comparable to that of C++ or Pascal, definitely faster than Smalltalk on comparable machines.
