Sci-fi writer Irving Millgate?

I noticed that The Blob lists a chap named “Irving Millgate” as a writer. It’s also the only writing credit he has on IMDB. A Google search of “Irving Millgate” gives no info other than “a writer of The Blob.”

Pseudonym, maybe? Anyone know the scoop? I’d think that after a notable movie like that he would have done something.

The IMDb says that Irving Millgate is also known as Irvine H. Millgate. If you do a Google on that name, you see that he is an author. If you check on one of the large bookstore websites, you’ll see that he wrote a number of books during the 1980’s and 1990’s. They seem to be about psychology or management. They’re all out of print.
