John Gruber (born 1973) is a technology blogger, UI designer, and one of the inventors of the Markdown markup language. Gruber is from Philadelphia, Pennsylvania. He received his Bachelor of Science in computer science from Drexel University, then worked for Bare Bones Software (2000–02) and Joyent (2005–06). In 2004, Aaron Swartz and Gruber worked together to create the Markdown language, with the goal of enabling people "to write using an easy-to-read and easy-to-write plain text format, optionally convert it to structurally valid XHTML (or HTML)".
