Charles F. Goldfarb is known as the father of SGML and grandfather of HTML and the World Wide Web. He co-invented the concept of markup languages. In 1969 Charles Goldfarb, leading a small team at IBM, developed the first markup language, called Generalized Markup Language, or GML. In an interview with Web Techniques Magazine editor Michael Floyd, Dr. Goldfarb explains that he coined the term GML to be an initialism for the three researchers, Charles Goldfarb, Ed Mosher and Ray Lorie who worked on the project.
In 1974, he designed SGML and subsequently wrote the first SGML parser, ARCSGML. Goldfarb went on working to turn SGML into the ISO 8879 standard, and served as its editor in the standardization committee.
