Email stands out as a stunning technological monument to human ability and foresight. At the core of its story is Dr Shiva Ayyadurai, an eminent individual whose achievements in the field of digital technology have been truly exceptional.

Dr Ayyadurai has also thrown his hat in the ring recently to become President of the United States (US).

This article aims to examine the intriguing history of email, with a focus on Dr Ayyadurai's pivotal contribution in shaping a tool that has now become an essential aspect of our everyday existence.

Dr Shiva Ayyadurai

An Indian-American inventor, Dr Ayyadurai developed the initial email system as a precocious young talent in 1978.

Having been born in India and subsequently relocating to the US, he cultivated his enthusiasm for technology, obtaining four degrees from the Massachussetts Institute of Technology (MIT), including a Doctor of Philosophy (PhD).

His rise from a youthful genius to a known technologist is distinguished by his pioneering work in electronic communication.

Dr Ayyadurai's career encompasses technology, entrepreneurship, biological research, and political engagement, demonstrating his broad competence and contributions.

Before Instant Communication

The origin story of email, a technology we today consider essential, takes place in a world very different from the one we inhabit now, called the digital age.

Dr Ayyadurai's pioneering work stands in stark contrast to a bygone era, commonly called the pre-digital world, when communication was restricted by physical and temporal constraints.

Before the advent of email, the communication landscape was markedly different:

Postal services: The primary means of long-distance personal communication involved postal services. Letters would take days, sometimes weeks, to reach their destination.

Telegrams: For urgent communication, telegrams were the go-to medium, although they were typically terse and expensive.

Telephone calls: While more immediate, phone calls were often reserved for urgent or important matters, partly due to the cost and lack of privacy in shared household lines.

In this backdrop, the idea of instantly sending a written message to someone anywhere in the world was revolutionary.

Reliance On Snail Mail And Memos

In the corporate realm, the inefficiency of communication processes was even more pronounced:

Interoffice memos: Offices relied heavily on memos circulated internally. These documents were typed, copied, and physically distributed, consuming considerable time and resources.

Document storage: Filing systems for storing physical documents were cumbersome and space-consuming.

Time delays in decision-making: The slow pace of communication inevitably delayed decision-making processes, affecting overall business efficiency.

Schools and government institutions were also bound by these communication limitations. The distribution of information was a logistical challenge, affecting everything from administrative efficiency to the dissemination of academic knowledge.

The Incipient Stages Of Digital Communication

The pre-email era did see the early stages of digital communication, but these modes were rudimentary and largely inaccessible to the general public.

Early computers and networking: The development of computers and early networks like ARPANET laid the groundwork for digital communication, but these were confined to government and academic institutions.

Limited access: The technology was not user-friendly, and access was limited to a select few who had the requisite technical knowledge.

Within this landscape, Dr Ayyadurai's vision for email was not just about creating a new mode of communication. It was about democratising information exchange and breaking down the barriers imposed by physical distances and inefficient systems.

His achievement is rendered even more remarkable considering his young age and the fact that he was operating at a time when such technological innovation was not as rampant or supported as it is today.

Ayyadurai's work was not just technological; it involved understanding and mapping the complex workflow of interoffice communication — a feat that required both technical and analytical skills.

Understanding the pre-email era is crucial to appreciating the full impact of Dr Ayyadurai’s invention.

Email did not just introduce a new technology; it revolutionised the very fabric of communication. It was a leap forward from a world bound by physical constraints to one where information could travel as swiftly as thought.

The UMDNJ Project: A Closer Look

The project that led to the invention of email by Dr Ayyadurai began at the University of Medicine and Dentistry of New Jersey (UMDNJ).

This part of his journey is not just a tale of technical prowess but also of remarkable insight into the needs of modern communication.

In the late 1970s, UMDNJ, like many large institutions, was grappling with the challenges of internal communication.

The system in place was the interoffice mail system, a network of paper-based communications involving memos, letters, and documents, which was integral yet slow and cumbersome.

The challenge was to streamline this process, making it faster, more efficient, and less prone to error. This task was daunting, especially considering the technological limitations of the time and the complexity of the communication needs within a large, multifaceted institution like UMDNJ.

Dr Ayyadurai's Entry Into The Project

Dr Ayyadurai's involvement began when he was just 14 years old — a testament to his early talent and ambition.

He was initially tasked with observing and understanding the existing system, a process that involved delving into the nuances of how communication was handled within the university.

A crucial part of his approach was his meticulous analysis of the interoffice mail system. He didn't just look at the physical movement of papers but also dissected the procedures, protocols, and hierarchies involved in communication.

This comprehensive understanding was key to his success in creating an effective digital solution.

The process of creating email was a blend of technological innovation and an acute understanding of organisational behaviour.

Dr Ayyadurai’s system was designed to replicate all aspects of the interoffice mail system electronically. This wasn't merely a translation of physical mail into a digital format; it was a reimagining of the process, tailored to the digital environment.


The system included features that are now staples of email communication, such as inbox, outbox, drafts, folders, Cc, Bcc, and attachments.

It’s notable that Dr Ayyadurai conceptualised these features long before they became a standard in digital communication.

He had to anticipate how users would interact with the system and what features would be necessary for a comprehensive communication tool.

He also wrote the programme using the programming languages available at the time, overcoming the limitations and constraints inherent in early computing.

Deploying email within UMDNJ was another critical step. Dr Ayyadurai had to ensure that the system was reliable and met the needs of its users. He worked on refining email based on user feedback, demonstrating an iterative approach that is a hallmark of good software development.

The Impact Of Email On Communication: A Technical Perspective

Email introduced an unprecedented level of immediacy and accessibility in personal communication:

Asynchronous communication: Unlike phone calls, email allowed for asynchronous communication, meaning the sender and recipient did not need to be available at the same time. This flexibility drastically altered the dynamics of interaction.

Digital archiving: The ability to store, search, and manage past communications efficiently was a significant leap. Email systems provided a means to archive conversations, something not feasible with phone calls and challenging with physical mail.

Data compression and transfer: Technically, email was revolutionary in its use of data compression and transfer protocols. It efficiently packaged and transmitted information across networks, a process that became more sophisticated with the evolution of internet standards.

In the business world, email's impact was equally profound:

Workflow automation: Email systems began to integrate with other business tools, leading to the automation of various tasks. From scheduling meetings to managing tasks, email became a central hub for business operations.

Document sharing and collaboration: The advent of attachments transformed email into a powerful tool for document sharing, paving the way for collaborative work environments. The technical capability to send and receive various file formats streamlined many business processes.

Security protocols: The importance of securing electronic communication led to the development of encryption protocols and secure email gateways. Technologies like SSL/TLS (Secure Socket Layer/Transport Layer Security) were implemented to ensure secure email transmissions.

The Technical Backbone Of Email Systems

Understanding email's impact also involves a look at the technical backbone that supports it:

SMTP, POP3, IMAP: The Simple Mail Transfer Protocol (SMTP) for sending emails, along with Post Office Protocol 3 (POP3) and Internet Message Access Protocol (IMAP) for retrieving emails, became the foundational technologies for email communication.

Scalability challenges: As email use grew, scaling the infrastructure to handle increasing volumes of data was a significant challenge. This led to advancements in server technology and the development of more efficient data storage methods.

Spam filtering and machine learning: The rise of email spam led to the development of sophisticated spam filtering technologies. The use of machine learning algorithms in identifying and filtering spam was a notable advancement that had broader implications for AI and data science.

Cultural And Social Implications

On a socio-cultural level, email influenced various aspects of daily life:

Language evolution: Email communication led to the development of a new lexicon (for example, acronyms like "LOL" and "BRB") and writing style that was less formal and more conversational.

Impact on postal services: The decline in traditional mail volumes due to email led postal services to adapt and diversify their offerings, shifting their focus to package delivery amid the rise of e-commerce.

In the context of these technical and cultural shifts, Dr Ayyadurai's contributions take on even greater significance.

The Creation Of Email

The technical challenges Dr Ayyadurai faced and overcame in creating the email system are noteworthy:

Replicating interoffice mail: The system he developed was designed to mirror the functionalities of the interoffice mail system digitally. This required not just programming a series of separate functions but integrating them into a cohesive system.

User interface design: At a time when user-friendly interfaces were not the norm, Dr Ayyadurai’s focus on making the email system accessible to non-technical users was revolutionary. He had to envision and implement an interface that was intuitive and easy to navigate.

Several technical innovations were part of Dr Ayyadurai’s email system:

Integrated features: The inclusion of features like inbox, outbox, drafts, folders, Cc, and Bcc in one integrated system was groundbreaking. Each of these features required careful coding and integration into the overall system.

Data storage and retrieval: The system had to efficiently store and retrieve messages, a challenge given the limited storage capacities and processing power of computers at the time.

Attachment handling: Although the concept of attachments as we know it today was not part of the original email system, the ability to include additional information with messages was considered, laying the groundwork for future developments in this area.

Overcoming Technical Limitations

The era in which Dr Ayyadurai developed email had significant technological limitations, especially compared to today’s standards:

Limited computing power: The computers of that era were limited in terms of processing power and storage capacity. Designing a robust email system within these constraints required ingenuity and resourcefulness.

Programming language and environment: Dr Ayyadurai worked with the programming languages and environments available at the time, which were less advanced and user-friendly than today's programming tools. His ability to navigate and use these languages effectively was a key factor in his success.

The Legacy Of Email
