The GNU Project was founded by [RichardStallman] (RMS) in 1984 to create a [Free]
operating system called GNU (which stands for GNU's Not Unix). GNU is
based on the UNIX design, however it does not strictly follow it; its developers often improve on the original Unix designs

By about 1990; most of the operating system was developed, short of a decent kernel (they had small, crude kernels they used for development but nothing stable). The GNU project developers were waiting for Mach to be released as free software before they started working on the GNU kernel [TheHurd] which was a collection of servers that ran over the Mach microkernel to provide a Unix like kernel.
Further delays with Mach and technical problems debugging Hurd set development back severely. In the meantime, Linus Torvalds started developing a small Unix-like kernel called "Linux" with the intention of making an operating system. (Linus took an opposite approach to the GNU project by starting on the kernel). The Linux community began making Linux versions of GNU packages, and it took a while before any real cooperation took place in combining GNU and Linux (possibly due to poor communication etc.) With a little bit of glue; Linux (the kernel) filled the gap in the GNU system and allowed people to run a complete free operating system.
The GNU Project requests the operating system is called GNU/Linux as opposed to Linux (or just GNU); to quote the [GNU/Linux FAQ | http://www.gnu.org/gnu/gnu-linux-faq.html]:
> "Most operating system distributions based on Linux as kernel are basically modified versions of the GNU operating system. We began developing GNU in 1984, years before Linus Torvalds started to write his kernel. Our goal was to develop a complete free operating system. Of course, we did not develop all the parts ourselves--but we led the way. We developed most of the central components, forming the largest single contribution to the whole system. The basic vision was ours too.
> In fairness, we ought to get at least equal mention"
