leading hotel in the city. It reopened by hosting the President of Italy in 1956 on his state visit, and again became the leading hotel in the then-capital of the Federal Republic, hosting heads of states (including U.S. Presidents Kennedy, Nixon, and Reagan), state dinners, and events hosted by the Chancellor of Germany. Wolters received so many commissions from the government of North Rhine-Westphalia that he opened an additional office in Düsseldorf. In 1955, Wolters won a competition to design the Industrie-Kreditbank building in Düsseldorf. Two years later, he was again successful in that city in a competition to design the Galarie Conzen. Wolters was awarded a prize for his design to reconstruct Düsseldorf's Altstadt (Old City). His son, Fritz Wolters, also an architect, described him as a man who fought uncompromisingly for what he saw as the "whole" in urban planning, and once ended a discussion with a local committee with the remark that they had "rented his head, not his pencil". Wolters also considered himself to be a "functionalist", designing a number of concrete, flat roofed, modern hospitals. In the 1960s, Wolters and his son shared an office until their architectural differences separated them, Fritz Wolters being more interested in the small details rather than in what he described as "epoch-making" solutions. However, their personal relationship survived this professional separation. In 1978, Wolters published a book on the town centre of Berlin, but despite suggestions from his son, he declined to include his views about Nazi architecture, and never did set forth such views to his colleagues. Association with Speer Spandau years Wolters did not attend the Nuremberg trial (he later described it as a "victor's court" and as a "show trial") but wrote to Speer in January 1946, during the trial: "I stand by you in misfortune as in the good days. I believe as before in your lucky star." On 10 August, as the trial approached its conclusion, Speer, anticipating the likelihood of a death sentence, wrote to Wolters asking him to "collect my work together for later ages and to recount much of my life. I think it will be honored one day." Despite his forebodings, Speer did not receive the death sentence, but on 1 October 1946 was given a sentence of twenty years in prison, and on 18 July 1947 was transferred to Spandau Prison to serve it.
