History

Linux was created by Linus Torvalds. The main component of Linux after which it is named is the kernel i.e., Linux Kernel. Initially, Torvalds wanted to call the kernel as Freax (to resemble Unix-like), but his friend suggested the name as Linux.

Linux was given as open-source project with minimal distribution for hobbyists

Linus holds the "Linux" trademark to monitor its use. He has the highest contribution in writing of Linux kernel. He is the main person which is responsible for committing changes onto the standard Linux kernel.

As per Wikipedia, the Linux Foundation currently sponsors Torvalds so he can work full-time on improving Linux.
