IMO, this could some it up. Victor Giglio was very likely a sort of "personal assistant" to Benjamin Guggenheim and his duties depended upon where they were and what they were doing at the time. In a working environment, Giglio would have performed duties of a personal secretary while in a situation like on-board the Titanic, he would become more of a valet. Overall, Giglio's position must have been a notch above that of a 'servant'; I have read that they were seen sitting next to each other on deck chairs, something a simple valet would never have done in those days.Giglio was valet (probably more of a secretary or personal assistant than a servant) to Mr Benjamin Guggenheim
No offence intended but on a lighter note, I sometimes refer to the pair as "Gig and Gug" for short while indulging in my habit of scribbling notes about Titanic related events.
