Who invented HTML?

Quote from Wikipedia HTML entry

In 1980, physicist Tim Berners-Lee proposed and created a prototype system, ENQUIRE, to enable researchers at CERN to use and share documents during his contract work at CERN. In 1989, Berners-Lee proposed an Internet-based hypertext system in a memo. He specified HTML and wrote browser and server software by the end of 1990. That same year, Berners-Lee teamed up with CERN data systems engineer Robert Carrio to apply for funding for the project, but it was not formally approved by CERN. In his personal notes, Berners-Lee lists “a few fields in which hypertext is used” and lists encyclopedias first.

The first public description of HTML came in a file called HTML Tags, written by Tim Berners-Lee in late 1991. It describes 18 elements, including the initial, relatively simple design of HTML. With the exception of hyperlink tags, the designs were heavily influenced by a standard General Markup Language (SGML) -based file format within CERN called SGMLguid. Eleven of these elements still exist in HTML 4.
