The Foundations: Early Computing Origins and the Birth of Virtual Machines
Martin Richards and BCPL: Pioneering Portability and Virtualization
In the mid-1960s, Martin Richards (British) from the University of Cambridge was facing a challenge. He needed a language that could run on different hardware platforms to aid in writing compilers and operating systems. To scratch this itch, he developed BCPL (Basic Combined Programming Language) in 1966. BCPL was a typeless language that prioritized simplicity and portability.
O-code and the Virtual Machine Concept
Richards introduced an innovative solution to achieve portability: O-code, an intermediate representation of BCPL programs. BCPL compilers translated source code into O-code, which was then executed by an O-code interpreter or compiled into machine code for the target hardware. This approach effectively created a virtual machine at the compiler level—a conceptual machine providing a consistent execution environment across different hardware platforms.
This abstraction allowed BCPL programs to be highly portable, as the same O-code could run on any system with an appropriate interpreter.
The Legacy of Virtual Machines
The virtual machine concept introduced by Richards set a precedent for future technologies aiming for portability and isolation:
Understanding this lineage empowers you to appreciate how virtualization has been a recurring solution to challenges in computing, offering portability, security, and resource management.
The Genesis of Multics and the Birth of Unix
Multics: Ambition Meets Complexity
In the early 1960s, accessing computer time was a significant hurdle. Fernando Corbató (American) at MIT wanted to scratch the itch of limited computer access for multiple users. This led to Project MAC, which, in collaboration with Bell Labs and General Electric (GE), initiated Multics (Multiplexed Information and Computing Service) in 1964.
Multics aimed to create a highly available, secure, and versatile operating system for multiple users. It introduced groundbreaking concepts:
- Time-Sharing: Multiple users sharing system resources simultaneously.
- Hierarchical File Systems: Organizing files in a tree-like structure.
- Dynamic Linking: Programs could use shared code libraries at runtime.
- Access Control: Fine-grained permission management.
However, Multics became resource-intensive and complex. Bell Labs grew frustrated with its unwieldiness and withdrew from the project in 1969, leaving room for a simpler solution.
Unix: Simplicity Born from Necessity
At Bell Labs, Ken Thompson (American) and Dennis Ritchie (American) were itching to have a functional operating system for their work after the departure from Multics. Using a spare PDP-7 machine, Thompson began creating a simpler system. In 1969, this effort resulted in Unix, a play on the name Multics, signaling a more straightforward approach.
Douglas McIlroy and Unix Pipes
An often-overlooked contributor, Douglas McIlroy (American), head of the Bell Labs Computing Sciences Research Center, had an itch to streamline data processing. He introduced the concept of Unix pipes, mechanisms allowing the output of one program to become the input of another. This innovation enabled users to combine simple tools to perform complex tasks, embodying the Unix philosophy of modularity and simplicity.
The Unix Philosophy: Empowerment Through Simplicity
Unix introduced principles that remain empowering:
- Everything is a File: Simplifies interaction with system components.
- Modularity: Encourages building small, focused programs.
- Piping and Redirection: Allows flexible data manipulation.
- Scripting: Automating tasks by combining commands in scripts.
By understanding and applying these principles, users can harness the full power of their systems, customizing functionality without relying on external entities.
The Development of C: Bridging Low-Level Control and High-Level Abstraction
As Unix began to spread within Bell Labs, portability became an issue. Dennis Ritchie (American) noticed the itch of needing a language that could facilitate Unix’s migration across different machines.
Influence of BCPL and Martin Richards
Drawing inspiration from BCPL, Ritchie developed the C programming language in 1972. C struck a balance between low-level hardware access and high-level programming constructs.

Evolution of Scripting and High-Level Languages: From Shell Scripts to Python
Shell Scripting and Stephen Bourne
The need to automate repetitive tasks led Stephen Bourne (British) at Bell Labs to develop the Bourne Shell in 1979. This allowed users to write scripts—a sequence of commands stored in a file—to streamline workflows.
Scratching Itches with Scripting
- Brian Fox (American) noticed the limitations of existing shells and released Bash (Bourne Again SHell) in 1989, enhancing scripting capabilities.
- Larry Wall (American), while working as a system administrator, created Perl in 1987 to make report processing easier. Perl offered advanced text processing and system administration tools.
These developments made scripting more powerful and accessible, allowing users to automate complex tasks efficiently.
The Rise of Python: Bridging Gaps
In the late 1980s, Guido van Rossum (Dutch) was working at the Centrum Wiskunde & Informatica (CWI) and found existing languages either too low-level or too cumbersome for his needs. He wanted to bridge the gap between the C world and the sysadmin world. In 1991, he introduced Python.

By embracing Python, users can participate in cutting-edge developments without reliance on proprietary tools or AI-driven interfaces.
An Alternative Timeline: The Road Not Taken with ITS and LISP
The Kooky Alternative: ITS and LISP
While Unix was spreading, an alternative computing philosophy was brewing at MIT. John McCarthy (American) created LISP in 1958 to handle symbolic computation, essential for artificial intelligence research.
Simultaneously, MIT developed the Incompatible Timesharing System (ITS) in 1967. ITS was a response to Multics but took a different approach, focusing on flexibility and user empowerment without strict security measures.
A Bizarro Computing World
Had ITS and LISP become the dominant paradigms, our computing landscape might have been vastly different:
- LISP Machines: Specialized hardware optimized for LISP could have become mainstream.
- Symbolic Computing: Emphasis on symbolic rather than numeric computation.
- Different Software Ecosystem: Tools and applications built primarily in LISP.
However, the simplicity, portability, and widespread availability of Unix overshadowed ITS and LISP. Unix spread rapidly, sometimes described as a virus, due to its accessibility and the community that formed around it.
Recognizing this alternative path highlights that the technologies we take for granted today were not the only possibilities. Understanding this empowers us to appreciate the choices and developments that shaped our current computing world.
