looking at old pictures tonight. On the left is my great grand father, Max Hannig Ulriksen, quite a character. He was an entrepreneur all his life, working with model planes (why do I like flying ?), photography (I have a business plan from him for a business in photography!), athletics including rowing, industrial machinery (stuff around steel)... His father was also an entrepreneur in the thermal water business, made a fortune, and then lost all of it in government bonds in WWI. His father Stanislaus, my great great grandfather, was born in what is now Poland, but Oriental Prussia back then.
Here we see Max in c. 1917 in his military service in Chile. Their uniform was modeled after the Prussian one, with the typical helmet. This is the Telegraph Batallion... 90 years later, I deal with telecoms in the Internet space !
