I just received this email and foto from Carlos who lives in Chile. I will list the foto first then paste in his emails to me.
Dear Brian:
I think you would find the adjoined photo very interesting. Its depicts my uncle Waldemar von Alten in the uniform of the Kaiser's Leibgendarmerie.
He was the Kaiser`s Standartenträger (Bannerbearer). He made the Boxer campaign in China and I gather that he died as a retired general in the Second World War. He pertained to the 1.Zug of the Feldgendarmerie. My father used to bear his helmet when he visited his uncle's house in Berlin as he was a child in 1913; it was very heavy. Uncle von Alten war a very tall man. I found your e-mail in pickelhaubes.com forum; I think you can publish the foto in the forum. I'm myself not a forum's member.
Send me your comments.Regards,
Carlos

I'm very happy at your comments. I have this unique foto, but I remember having seen years ago a movie restored digitally by the BBC featuring a German Parade in Berlin, the same Parade during which this foto was made. In the first plane the Kaiser, then my uncle. I also remember having read a german book on Imperial Germany with another similar foto in the first page. It was a close up showing very clearly the Kaiser Willhelm II and my uncle. The helmet in question was made of tombak, a very brilliant copper alloy. I have a very good command of german, as you can guess, being of german origin by father and mother.
Regards, Carlos
I would guess that some of our members have seen this BBC production or even fotos of von Alten and the Kaiser. Now we have a name and some family history. If anyone has additional information on von Alten please post it. I love this hobby! Thanks to Carlos for providing this information!! Brian
