Less was created in 2009 by Alexis Sellier, more commonly known as @cloudhead. Originally written in Ruby, it was then ported to JavaScript.
Less was originally inspired by Sass, with a leaner feature set and a syntax closely matching CSS, which Sass did not have at the time. (Sass was later inspired by Less to create SCSS, its own CSS-like syntax.)
In May 2012 Alexis turned over control and development to a core team of contributors who now manage, fix and extend the language.
