Uncovering the Hidden History Behind Dijkstra’s Critique of Object-Oriented Programming
In the world of programming, the debate between structured programming and object-oriented programming has been ongoing for decades. One of the most famous critics of object-oriented programming was Edsger Dijkstra, a renowned computer scientist known for his contributions to the field of programming languages and algorithms. In this article, we will delve into the hidden history behind Dijkstra’s critique of object-oriented programming and explore the reasons behind his skepticism.
Who was Edsger Dijkstra?
Before we dive into Dijkstra’s critique of object-oriented programming, it’s essential to understand who Dijkstra was and why his opinions held significant weight in the field of computer science. Edsger Dijkstra was a Dutch computer scientist who is best known for his work on algorithms, programming languages, and software development methodologies. He received the Turing Award in 1972 for his fundamental contributions to the development of programming languages.
The Rise of Object-Oriented Programming
Object-oriented programming (OOP) gained popularity in the 1980s and 1990s as a programming paradigm that organizes data and functions into objects. Proponents of OOP argue that it improves code reusability, modularity, and maintainability by encapsulating data within objects and allowing for inheritance and polymorphism. However, Dijkstra was not convinced of the benefits of this approach.
Dijkstra’s Critique of Object-Oriented Programming
Dijkstra’s skepticism towards object-oriented programming stemmed from his deep-seated belief in the importance of rigorous program construction and verifiability. He argued that OOP introduced unnecessary complexity and obscured the underlying logic of programs. Dijkstra believed that the focus on objects and classes in OOP distracted programmers from writing clear, concise, and provably correct code.
The Hidden History Behind Dijkstra’s Critique
To understand the roots of Dijkstra’s critique of object-oriented programming, we need to delve into the historical context of the development of programming languages and methodologies. Dijkstra was a proponent of structured programming, a programming paradigm that emphasizes the use of well-structured control flow and modular design. He believed that structured programming provided a clear and logical way to write and understand programs, leading to more robust and reliable software.

Dijkstra’s critique serves as a reminder of the importance of clarity, simplicity, and correctness in software design and implementation.
Conclusion
In conclusion, the hidden history behind Dijkstra’s critique of object-oriented programming sheds light on the complex relationship between programming paradigms and the principles of software engineering. While OOP has become a dominant approach in modern software development, Dijkstra’s criticisms remind us of the importance of rigorous program construction and verifiability. By understanding the historical context and motivations behind Dijkstra’s critique, we can gain a deeper appreciation for the evolution of programming languages and methodologies in the field of computer science.
