Lawrence G. Roberts (December 21, 1937 – December 26, 2018) was an American scientist. He is often called one of the "founding fathers" of the Internet. He won the Draper Prize in 2001 and the Principe de Asturias Award in 2002. These awards recognized his important work in developing the Internet.
Roberts played a key role in creating the ARPANET. This was an early computer network that used a new method called packet switching. The ARPANET was a very important step towards the modern Internet we use today.

Who Was Lawrence Roberts?
Lawrence G. Roberts was born in Connecticut, USA, in 1937. From a young age, he was interested in technology and computers. He studied at the Massachusetts Institute of Technology (MIT). This is a famous university known for its science and engineering programs. He earned his degrees there, including a Ph.D. in electrical engineering.
After finishing his studies, Roberts worked at MIT Lincoln Laboratory. This lab focused on advanced research. His work there helped him prepare for his biggest project: building the ARPANET.
The Birth of the Internet: ARPANET
In the 1960s, computers were large and expensive. They usually worked alone. Scientists wanted to find a way for computers to talk to each other. This would allow them to share information and resources.
Roberts joined the Defense Advanced Research Projects Agency (DARPA) in 1966. DARPA is a US government agency that develops new technologies for the military. His boss, J. C. R. Licklider, had a vision for a network of computers. Roberts was chosen to lead the project to make this vision real.
He designed and managed the creation of the ARPANET. This was the first large-scale computer network. It connected computers at different universities and research centers. The ARPANET officially started in 1969.
What is Packet Switching?
A key idea behind the ARPANET was "packet switching." This method was invented by British computer scientist Donald Davies. Before packet switching, if you sent data, it would travel as one continuous stream. If the connection broke, the whole message was lost.
Packet switching works differently. It breaks down data into small pieces called "packets." Each packet travels independently across the network. They can even take different paths to reach their destination. Once all packets arrive, they are put back together to form the original message. This made networks much more reliable and efficient. Roberts saw the value in this idea and made it central to the ARPANET.
Building the Network
Roberts faced many challenges in building the ARPANET. He had to convince different organizations to join the network. He also had to choose the right technologies and protocols. Protocols are like rules that computers use to communicate.
The first four computers connected to the ARPANET were at:
- University of California, Los Angeles (UCLA)
- Stanford Research Institute (SRI)
- University of California, Santa Barbara (UCSB)
- University of Utah
This network allowed researchers to share data and even run programs on distant computers. It was a huge step forward in how people used computers.
After ARPANET
After his work on the ARPANET, Roberts continued to innovate. In 1973, he left DARPA to start the first public packet-switched network. This company was called Telenet. Telenet was like an early version of an Internet service provider (ISP). It allowed businesses and individuals to connect to a network using packet switching.
Telenet showed that packet switching could work for commercial use. It proved that the technology was not just for research. This helped pave the way for the Internet to become available to everyone.
His Amazing Legacy
Lawrence Roberts' work on the ARPANET was foundational. It laid the groundwork for the global Internet we know today. Without his vision and leadership, the Internet might not exist in its current form. He helped create the system that allows billions of people to connect, share, and learn every day.
His contributions changed the world. They made it possible for us to send emails, browse websites, stream videos, and connect with friends online. He truly was a pioneer of the digital age.
Awards and Recognition
Roberts received many awards for his groundbreaking work. Some of his notable honors include:
- IEEE Computer Pioneer Award: This award recognizes individuals who have made significant contributions to the computer field.
- IEEE Computer Society W. Wallace McDowell Award: Another prestigious award from the Institute of Electrical and Electronics Engineers.
- Charles Stark Draper Prize: Often called the "Nobel Prize of Engineering," this award recognized his role in developing the Internet.
- Principe de Asturias Award: A major international award from Spain, honoring his contributions to science and technology.
These awards highlight the lasting impact of his work on technology and society.
