My dad was a captain and worked for most of his life for Isthmian and States Marine Lines. Along with my brother (the webmaster) and another son of a captain from Baltimore (the historian), we maintain historical sites for these 2 shipping lines that no longer exist. There is also a forum (like we have here) for the exchange of information. We have an impressive array of ship photos and company history.
