Not really, no. But: the first commercial firewall was Ranum's DEC SEAL. Ranum is an old-school Unix programmer. The first book on firewalls is "Firewalls and Internet Security", by Bellovin and Cheswick, who previously created one of the first firewalls (predating DEC SEAL) and possibly coined the name. Both of them are, as you'd expert, Unix nerds.

People were building firewalls in 1988, several years before there was even Trump Winsock, let alone a reason for PCs to need to filter Internet traffic.
