his writings, Speer claimed to have finished five thousand books while in prison. His sentence of twenty years amounted to 7,305 days, which only allotted one and a half days per book. Speer's supporters maintained calls for his release. Among those who pledged support for his sentence to be commuted were Charles de Gaulle and US diplomat George Wildman Ball. Willy Brandt was an advocate of his release, putting an end to the de-Nazification proceedings against him, which could have caused his property to be confiscated. Speer's efforts for an early release came to naught. The Soviet Union, having demanded a death sentence at trial, was unwilling to entertain a reduced sentence. Speer served a full term and was released at midnight on 1 October 1966. Release and later life Speer's release from prison was a worldwide media event. Reporters and photographers crowded both the street outside Spandau and the lobby of the Hotel Berlin where Speer spent the night. He said little, reserving most comments for a major interview published in Der Spiegel in November 1966. Although he stated he hoped to resume an architectural career, his sole project, a collaboration for a brewery, was unsuccessful. Instead, he revised his Spandau writings into two autobiographical books, Inside the Third Reich (in German, Erinnerungen, or Reminiscences) and Spandau: The Secret Diaries. He later published a work about Himmler and the SS which has been published in English as The Slave State: Heinrich Himmler's Masterplan for SS Supremacy or Infiltration: How Heinrich Himmler Schemed to Build an SS Industrial Empire (in German, Der Sklavenstaat - Meine Auseinandersetzung mit der SS). Speer was aided in shaping the works by Joachim Fest and Wolf Jobst Siedler from the publishing house Ullstein. He found himself unable to re-establish a relationship with his children, even with his son Albert who had also become an architect. According to Speer's daughter Hilde Schramm, "One by one my sister and brothers gave up. There was no communication." He supported Hermann, his brother, financially after the war. However, his other brother Ernst had died in the Battle of Stalingrad, despite repeated requests from his parents for Speer to repatriate him. Following his release from Spandau, Speer donated the Chronicle, his personal diary, to the German Federal Archives. It had been edited by Wolters and made no mention of the Jews. David Irving discovered discrepancies between the deceptively edited Chronicle
