Either he didn't exist, or nothing is known about him
Take your pick, really.
Having searched through the text of Philosopher's Stone and Chamber of Secrets, as well as Pottermore, accio-quote.org, and a broad-spectrum Google search, I can find no reference to any other Muggle Studies professors besides Quirrel and Burbage, except for one: the alleged Wikia itself.
According to their own page on the character, he is mentioned only in the Chamber of Secrets video game (with some possible appearances in the films, almost certainly as part of crowd scenes where many unidentified faculty are present).
Although Rowling is known to have had a not-insignificant amount of input into the video games, it's not clear to what extent she influenced this particular creative decision. The earliest reference to a Muggle Studies professor I can find is from some "idle jottings", allegedly circa Prisoner of Azkaban1, posted on her old website; I can't find this image on the archived text-only version (funny, that), but I found a screenshot someone kindly saved:
Although the professor is unnamed, it appears as though Rowling initially planned for them to be male, but then changed her mind and switched to female.
Since this almost certainly predates the Chamber of Secrets game, we're left with three possibilities:
- The reference in the game is a nod to this; either Rowling or someone involved in the production of the game decided to canonize Rowling changing her mind, by literally having the character change
- The game was in error, and it was not caught in time and/or not deemed significant enough to correct
- The game made this fact up, for reasons known only to themselves
However, this is the only information I've been able to find on the character. If he existed, this is the sum of the publicly-available knowledge on him.
1 Note that the name for the Divination professor appears to be "Mopsus"; Mopsus is an early character Rowling talks about in an ITV press conference in 2005, and suggests he got cut while writing Philosopher's Stone:
[A]t one point there was a blind character who went by the name of Mopsus [...] he sort of that was a very early character and he had the power of second sight, in other words he was a bit like Professor Trelawney, he was a very, very early character, this was when I was drafting Philosopher's Stone, the reason I cut him was he was too good.
So either my interpretation is wrong and the character of Mopsus was dropped later (merely cut from the final draft of Philosopher's Stone), or these scribbles are a good bit older than Rowling claims.
