Linus Torvalds created Linux and later Git, two tools that became invisible infrastructure for modern technology. Linux began as a hobby kernel for personal computers, then grew through open-source collaboration into the core of servers, Android phones, embedded devices, supercomputers, containers, and cloud platforms. Git began as a tool to manage Linux development, then became the default way software teams track and share code. Torvalds' impact is practical and daily: much of the internet runs on Linux, and much of the software world builds with Git.

What they built
Companies & roles
Linux Kernel Project
Creator & lead maintainer
1991–
Started as Torvalds' personal kernel project in 1991 and grew into one of the largest collaborative software efforts in history. The Linux kernel now sits under Android, most web servers, cloud infrastructure, networking equipment, embedded systems, and many supercomputers.
Git
Creator
2005–
Torvalds built Git in 2005 when the Linux project needed a fast distributed version-control system. It solved practical problems around branching, merging, history, and trust, then spread far beyond Linux to become the standard workflow for software teams worldwide.
Impact
How they changed tech
Linux kernel
Linux is a free, collaborative operating-system kernel that manages hardware, processes, memory, filesystems, and drivers. Because it can be adapted and redistributed, it became the foundation for Android phones, servers, routers, TVs, cars, industrial devices, supercomputers, and the cloud machines behind everyday apps.
Open-source at planetary scale
Linux proved that thousands of contributors, companies, and maintainers could build critical infrastructure in the open. Its success changed business attitudes toward open source, showing that shared code could be reliable, secure, commercially useful, and strong enough to beat closed alternatives in servers and infrastructure.
Git
Git made distributed version control fast and practical for large projects. Developers could clone full histories, work offline, branch cheaply, review patches, merge work, and recover from mistakes, which changed collaboration norms for open-source projects, startups, enterprises, and platforms such as GitHub and GitLab.
Maintainer culture
Torvalds' role as Linux's long-term maintainer shaped how large open-source projects organize trust, review, releases, and technical authority. His code-first culture has been influential and sometimes criticized, but the maintainer model he helped popularize remains central to large shared infrastructure projects.
Cloud and container foundations
Linux became the common operating layer for cloud computing and containers because it was portable, scriptable, and deeply understood by infrastructure teams. Technologies such as namespaces, cgroups, and filesystem support made it possible to package and isolate applications at the scale modern services require.

Interesting facts
- •Linux started as a student project in Finland.
- •He named Git — slang he liked for himself as a “git.”
- •Android, most cloud VMs, and many routers run Linux under the hood.
- •He still oversees Linux kernel releases.
- •GitHub and GitLab popularized Git for every kind of team.
- •The Linux kernel is used in all of the TOP500 supercomputers in recent rankings.
Why it matters
Legacy
Torvalds' legacy is infrastructure that works so well many users never notice it. Linux made open-source operating systems central to the internet, mobile devices, cloud platforms, and embedded computing. Git changed how software itself is built, reviewed, shared, and remembered. Together they form two invisible engines under modern tech: one runs the machines, and the other coordinates the people changing the code.
