Can you imagine developing software without elegant frameworks, modular libraries, dynamic typing, or automatic memory management? Today‘s code syntax stands on the shoulders of pioneering languages that introduced foundational programming paradigms making modern software engineering possible.
In this comprehensive guide, we‘ll explore the origins of programming – no prior computer science knowledge needed! You‘ll uncover the geniuses, innovations, and historical forces that transformed programming from flipping switches to flawless mobile apps downloading in seconds.
Let‘s embark on an exciting journey through time discovering how the earliest computer languages shaped the world we live in today!
The Blank Canvas: Programming Before Higher Level Languages
To truly appreciate the visionary leaps early languages enabled, we first need to understand the primitive state of affairs preceding their arrival…
In the 1940s, interacting with hulking racks of vacuum tubes and wires was extremely laborious. For ENIAC‘s hardware programmers, this process involved physically resetting 3000 switches and reconnecting colored cables running between components. Now envision doing this over and over just to run different programs!
Thankfully, innovations elsewhere were setting the stage for programming syntax through punch cards, alongside crucial hardware advances allowing instructions to be electronically stored. Once capabilities like registers, memory storage, conditional branching, and I/O emerged, the landscape was ripe for the catalyzing potential of assembly languages.
The inability to symbolically input portable instructions was a glaring limitation programmers were desperate to overcome. We‘ll pick up the timeline from this breakthrough moment next…
#1: Assembly Language – 0s and 1s No More!
Year: 1947
Pioneer: Kathleen Booth
Against the backdrop of burdensome manual programming, Kathleen Booth envisioned an easier way…
While working on the ARC2 at Birkbeck College in 1947, Booth created the first assembler to automatically translate symbolic assembly code into numeric machine code, sparing programmers from manually setting bit patterns!
For example, the instruction STR R3, =X representing "store register 3 into memory location X" corresponded to machine code 1001001100000000. Assembly languages bridged this crushing complexity gap through mnemonic opcode abbreviations understandable by humans!
Pioneering Features:
- Mnemonic opcodes: USE
ADDinstead of01001 - Symbolic memory: Reference locations by
Xrather than01010101 - Portability: Same code works on different hardware
Booth‘s groundbreaking innovation soon spread across the industry, establishing assembly‘s niche still filled efficiently handling embedded and low-level use cases today!
Through this lens, we‘ll explore 7 more languages pivotal in the origins story of programming…
#2: Short Code – Math Notation Arrives!
Year: 1949
Pioneer: John Mauchly and William Schmitt
Physicist John Mauchly joined forces with programmer William Schmitt tackling budding inefficiencies as Short Code for the Binac emerged…
While hugely impactful, assembly languages still focused solely on memorizing numeric operation codes. Expressing math intuitively was not possible. If programmers wanted to multiply X by Y, this expanded manually into laborious adds and shifts buried across lines of codes!
Short Code was the first language introducing math notation through operators like * / + - incorporated directly into the syntax! Imagine seeing X * Y instead of littering multiple ADD and bitwise instructions everywhere – this dramatically improved readability.
Pioneering Features:
- Math operators:
X * Yinstead of complexADDsequences - Subroutines: Reusable code blocks for common logic
- Comments: Annotate explanations not impacting output
By allowing math directly in code, Short Code planted the seeds for Even Easier languages like FORTRAN around the corner!
#3: Autocode – Enter Compilers!
Year: 1952
Pioneer: Alick Glennie
Meanwhile in Manchester, England, scientist Alick Glennie was busy revolutionizing how programmers could translate source code using Autocode…
Thus far, conversion from programming languages into executable binary was extremely taxing. After writing code, entire sequences had to be painstakingly hand translated line-by-line into numeric machine form requiring skills akin to encryption! This manual effort essentially had to be redone for each new program written.
Glennie streamlined everything through authoring the first compiler capable of direct one-step translation! This automated technique parsed Autocode once and forever into intermediary software stealthily handling conversion behind the scenes after. Even math notation was generously supported without programmer involvement!
Pioneering Features:
- Compilation: Single-step translation process
- Math expressions:
A = C + (E/F)built-in - Subroutines: Reusable logic chunks to avoid redundancy
What used to take days was now solved in minutes thanks to Glennie‘s ingenious compiler opened the floodgates for soaring productivity!
#4: FLOW-MATIC – Influencing Business Programming
Year: 1955
Pioneer: Grace Hopper
…Many key players were pioneering easier languages for scientific computing amidst commercial demand accelerating rapidly.
Grace Hopper navigated this terrain through designing FLOW-MATIC in 1955, one of the first languages embracing English vocabulary. Concerned that programmers wasting time converting math calculations should instead be focusing on business problems, Hopper introduced terminology resonating intuitively with data processing workflows.
For instance, EXAMINE INVENTORY REQUIREMENTS clearly conveys validation logic to English readers yet remains unambiguous for compiling! Such vocabulary structuring the programming lexicon still impacts languages today.
Pioneering Features:
- English Dictionary:
REQUEST...SUPPLY...GENERATE - Data & File Focus: Purpose-built for business I/O
- Self-Documenting: Readability mirroring natural language
While Hopper‘s pioneering FLOW-MATIC saw limited use itself, the paradigm shift influenced COBOL‘s design immensely merging math notation with syntax resembling the English language!
#5: FORTRAN – Number Crunching Game Changer!
Year: 1957
Pioneer: IBM Team led by John Backus
Technology giant IBM responding to growing user demand delivered innovative FORTRAN (Formula Translation) in 1957 through visionary John Backus leading corporate development…
While business computing carried momentum, number crunching use cases were flying under the radar. Areas like engineering, physics, statistics lacked languages tailored for math-heavy workloads. Backus assembled specialists to create pragmatic FORTRAN focusing on what scientists needed most – efficient arrays/loops manipulation!
Instead of hand-crafting lookup tables across spreadsheets or using clunky machine code for multivariate analysis, FORTRAN enabled:
DIMENSIONS A[1:1000,1:1000]
DO 20 I = 1, 1000
DO 20 J = 1, 1000
A[I][J] = I + JWith such capabilities to manipulate matrices natively, adoption skyrocketed among engineering and scientific programming over ensuing decades!
Pioneering Features:
- Arrays/Matrices: Built-in bulk data structures
- Loops/Branches: Iteratively process array elements
- English Keywords:
DODIMClarify semantics - Libraries: Math/statistical functions provided
Given FORTRAN‘s immense legacy numerics-wise, later languages simply built upon these advances focusing elsewhere!
#6: COBOL – Legacy Business Glue!
Year: 1959
Pioneer: CODASYL Consortium
…As FORTRAN‘s analytical superpowers thrived commercially, the longstanding gap remained addressing administrative company problems using technology. Recognizing command over business infrastructure as vital for America‘s interests, the defense department collaborated with industry experts through an entity called CODASYL to develop Common Business-Oriented Language (COBOL) filling this void in 1959.
COBOL built upon FLOW-MATIC‘s English influence tailored for commerce needs like reports generation. Design priorities focused on clerks/accountants directly interacting with data. Self-documenting code mimicking business correspondence enabled widespread adoption by non-technical staff:
COMPUTE SALARY-WITH-RAISE =
SALARY * (1 + RAISE-AMOUNT / 100)
DISPLAY EMPLOYEE-NAME, SALARY-WITH-RAISEThanks to COBOL‘s specialization shoring historical shortcomings handling transaction outputs/formats, governmental & financial systems secured reliable technology foundations!
Pioneering Features:
- English:
ADDINVENTORY-TOTALS - Print Formatting: Page layout configuration
- Data Manipulation: Sorting algorithms built-in
- Processes: Inter-department workflows orchestration
With over 200 billion lines written until today, COBOL remains entrenched across banking/commerce supporting mission-critical infrastructure modern systems integrate with behind the scenes!
#7: LISP – Unlocking AI Potential!
Year: 1958
Pioneer: John McCarthy
Turning our attention from historical system programming darlings like COBOL/FORTRAN, the 1950s featured crazy geniuses tackling futuristic domains like artificial intelligence…
Amidst the daring landscape dotted with optimists attempting the impossible sat trailblazer John McCarthy at MIT. Recognizing puny languages straining against the complexity burgeoning AI entailed, McCarthy worked on LISt Processing (LISP) tackling limitations head-on.
Unlike stagnant static data of business languages, McCarthy built LISP around dynamic self-modifying structures from ground up. LISP code consisted entirely of nested lists able to shape-shift recursively in real-time by design!
(define flip
(lambda (f)
(lambda (x y)
(f y x)
)
)
)Such architectural strategies harnessing the power of lists paved the way for devising programs juggling rules/combinatorics at scale – the heart of artificial intelligence techniques like expert systems and logic programming today!
Pioneering Features:
- Lists: Central data structure
- Mutable: Code and data dynamically editable
- Functions: First-class objects
- Garbage Collected: Automatic memory management
LISP‘s specialized abilities encouraged computer scientists probing uncharted territory in coming decades to make the impossible possible!
#8: C – The System Glue!
Year: 1972
Pioneer: Dennis Ritchie
No language timeline is complete without the inimitable C touching literally all software arenas today…
Stemming from Ken Thompson and Dennis Ritchie pioneering Unix in Bell Labs, the aptly named C sought staying power sustaining operating system evolution. By combining high-level conveniences like English syntax with low-level direct memory access for performance, C bridged gaps between human and machine!
C delivered the missing link cementing systems-level programming for decades ahead through flexibility untying developers from fixed hardware setups:
while (x <= MAX && y >= MIN) {
z = optimize(arr, x, y);
if (z < pivot)
x++;
else
y--;
}With C providing the nuts-and-bolts toolbox for crafting compilers/kernels, engineers suddenly held reusable infrastructure enabling unprecedented software capabilities stacking onto hardware advances!
Pioneering Features:
- Portability: Hardware-agnostic high-performance
- Structures/Pointers: Complex memory/data modeling
- Preprocessor: Meta-programming for macros/includes
- Libraries: Reusable OS modularization
The universal nature of C catalyzing systems programming combined with deliberately sparse syntax encouraged the diverse C-derived languages powering modern computing ecosystems today!
