Steven Wintle
From Jenny Everywhere Wiki
Steven Wintle, also known by the Internet user handle Moriarty, is widely acknowledged as the creator of Jenny Everywhere; although the brainstorming of the character was a collective effort on the Barbelith forums, it was Wintle who drew the original public-domain sketches of the character and coined Jenny's canonical description as well as “the Paragraph”.
Wintle has, however, created relatively few Jenny stories: COMIC: Cars, the earliest, but unfinished, Jenny story, and the late COMIC: Tribute.
