Who is credited with the invention of e mail

The invention of email is a matter of debate, and there are several individuals who have been credited with its development. Here are a few notable ones:

1. Ray Tomlinson: Tomlinson is often credited with inventing email as we know it today. In 1972, he wrote the first email program, called SNDMSG, which allowed users to send messages to each other. He also introduced the "@" symbol to separate the user name from the host name in an email address.
2. Larry Roberts: Roberts was a computer scientist who worked on the development of the ARPANET, a precursor to the modern-day internet. In 1971, he wrote a program called SNDMSG, which allowed users to send messages to each other. This program is considered one of the earliest forms of email.
3. Vint Cerf and Bob Kahn: Cerf and Kahn are often referred to as the "fathers of the internet." They developed the TCP/IP protocol, which is still used today to route traffic on the internet. They also worked on the development of email, and their work laid the foundation for the modern email system.
4. Shiva Ayyadurai: Ayyadurai is an Indian-American inventor who claims to have invented email in 1978, while he was a student at the University of Medicine and Dentistry of New Jersey. He developed a program called "Email" that allowed users to send and receive messages, and he has been recognized by the US Congress for his contributions to the development of email.

It's worth noting that the development of email was a collaborative effort, and many individuals contributed to its evolution over the years. While it's difficult to identify a single inventor of email, these individuals are often credited with making significant contributions to its development.
