There is no creator credit. Norman Jolley wrote the first episode, "The Monster," in which we're told about Erskine being a widower and how his wife died. Charles Larson wrote the fourth episode, in which more background about Erskine is revealed, including the fact he got married at a young age. Barbara Erskine observes at 19 she is older than her father was when he got married. Larson also was the first-season producer and Jolley was the first-season associate producer, so presumably they had a lot of input.
