Q:Given the following context:  In 1951, with secret means of communications established, Wolters sent his first letter to Speer in five years.  He suggested that Speer move ahead with his memoirs.  In January 1953, Speer began work on his draft memoirs, and over the next year lengthy missives, sometimes written on tobacco wrappings or candy wrappers but most often on toilet paper, made their way to Wolters' office in Coesfeld.  Marion Riesser, who had continued as Wolters' secretary as he began private architectural practice, transcribed these notes into as many as forty closely typed pages per missive, and the draft totalled 1,100 pages.  Wolters objected that Speer called Hitler a criminal in the draft, and Speer presciently observed that he would likely lose a good many friends were the memoirs ever to be published.  Wolters had come to believe that reports of Nazi genocide were exaggerated by a factor of at least ten, that Hitler had not been given credit for the things he did right and that Germany had been harshly treated by the Allies.In the mid-1950s, Wolters quarrelled with Kempf who effectively dropped out of the network for a number of years, adding to the burden on Wolters and Riesser.  While Speer's pleas for his former associate and his former secretary to work together eventually brought about a healing of the breach, this was to some degree superficial as Kempf was aware that Wolters, even then, disagreed with Speer's opinions.  Wolters questioned Speer's readiness to accept responsibility for the Nazi regime's excesses and did not believe Speer had anything to apologise for, though the strength of his feelings on this point was kept from Speer—but not from Kempf and Riesser.Wolters was tireless in his efforts on behalf of Speer and his family to such an extent that his son, Fritz, later expressed feelings of neglect.  For Speer's fiftieth birthday in March 1955, Wolters gathered letters from many of Speer's friends and wartime associates, and saw to it that they made their way inside the walls of Spandau in time for...  answer the following question:  What is the last name of the person who made Fritz feel neglected?
A:
Wolters
