Eric Feiling
From Tootsville Wiki-Wiki
Eric Feiling was a programmer who worked mostly on Persephone and took over as the lead front-end programmer after the departure of Robert Dawson.
He was often online as BlackDaddyNerd.
Feiling also developed the Zookeeper program, which made it easier for the Art department to create new rooms and introduce special furniture items into the game world. During Tootsville IV, after all of the programmers had quit, Sean King was able to use Zookeeper to continue to introduce new scenes and special events in Tootsville for quite some time.
