I found this picture on some website an it says that it is William Murdoch and Charles lightoller standing together, I know that the man standing to the right is murdoch, but it says the man standing to the left is lightoller. but he has a mustache and I don't think Lightoller had a mustache.
Ah yes - as I thought, it is the Medic photo. The image is cropped from a larger photograph of the Medic's officers taken in 1900 that, last I heard, was in the collection of Maureen Landreth (a relative of James McGiffen, who is also in the original photograph). Lightoller was fourth officer and Murdoch was third.
Too bad they don't have the uncropped Medic photograph on there. As I'm sure Inger will agree, it is a fantastic picture, between the mustaches and poses. The style must have changed between 1900 and 1912, since the majority of the officers were clean shaven by the time of the maiden voyage. If I remember correctly, the picture is in Susanne Stormer's first book about Murdoch.
It is indeed a tremendous array of bristling moustaches! There's a great photo of Harold Lowe taken a few years after that one with a group of officers similarly sporting tremendous lip warmers (although Lowe, peversely, remained - and seems to have always remained - clean shaven).
I have just noticed the correspondence in this thread regarding White Star officers and their moustaches (or lack of them). Can I offer a suggestion why the Titanic's deck officers might have shed their facial hair. As far as I can make out, the officers on prestigious British ocean liners were encouraged to become naval reservists and, as such, they would not have been allowed to have moustaches without accompanying beards - it was a case of all or nothing!
