I have recently received the new catalogue and enjoyed reading in it. In the beginning there is an overview of Walter Lange's family all the way from Gutkaes to Walter Lange. Does he have children who are now working at A Lange & Söhne. Despite Lange being owned by Richmont it is nice that the company has heirs of the original family employed. Hope someone can enlighten me.
I dont think Herr Walter Lange has children of his own. I think having heard or read that he adopted Benjamin Lange as his son. Again I dont remember exactly but I think Benjamin is ´from´ the Rudolf Lange branche of the Lange dynasty.
In "The Revival of Time" written by Walter Lange, he mentions in page 166 Benjamin Lange (as his godchild) comes from Richard Lange's line. Walter Lange himself is from Emil Lange's line (Adolph --> Emil --> Rudolf --> Walter).
