Friedrich Percyval Reck-Malleczewen (11 August 1884 – February 1945) was a German author. His best-known work is Diary of a Man in Despair, a journal in which he expressed his passionate opposition to Adolf Hitler and Nazism.^[1] He was eventually arrested by the Nazis and died at the Dachau concentration camp.

Friedrich (Fritz) Reck-Malleczewen was born on the estate of Malleczewen, Masuria (Maleczewo, Poland), the son of the Prussian politician and landowner Hermann Reck. He originally wanted to be a musician, and at one point studied medicine in Innsbruck. He served as an officer in the Prussian Army but was dismissed due to diabetes, and later married Anna Louise Büttner in 1908. They had three daughters and a son before divorcing in 1930.

Graduating in 1911, Reck was a ship's doctor, in American waters, for a year. Thereafter he moved to Stuttgart to become a journalist and theatre critic for the Süddeutsche Zeitung, moving to Pasing near Munich in 1914. In 1933 Reck converted to Catholicism^{[citation needed]}, and in 1935 he married Irmgard von Borcke, with whom he had another three daughters.

Throughout the 1920s and 1930s, Reck was also a novelist, mainly of children's adventure stories. One book, Bomben auf Monte Carlo, has been filmed four times. Many of his books were banned by the Nazis, and more were not published until years after his death. In 1937 he published a historical novel on the Münster rebellion, Bockelson: History of a Mass Delusion, seen as a critical allegory of Hitler and Nazism.^[2] Today his best-known work is Diary of a Man in Despair (Tagebuch eines Verzweifelten), his journal of life as a dissident intellectual under dystopian Nazi rule. It was published for the first time in 1947, republished in 1970 in English translation by Paul Rubens, and reissued by New York Review Books in 2013.^[3]

Reck noted in his journal, in October 1944, that the Nazi authorities were becoming suspicious of him. On 13 October, he was arrested and charged under German military law with the serious offence of "undermining the morale of the armed forces," which could be punished by death on the guillotine. After some days in prison, he was released following the surprise intervention of an SS general.^[4] However, he was arrested again on 31 December and charged with "insulting the German currency." This appeared to be the result of a letter he had written to his publisher, in which he had complained that the inflation rate was eroding the value of his royalties.^[5] On 9 January 1945, he was transferred to the Dachau concentration camp, where accounts of his death differ; one source suggests that Reck was executed there 23 February, shot in the neck (Genickschuss),^[6] while the official death certificate recorded a death from typhus on February 16.^[3]

In April of 1945 Dutch writer Nico Rost encountered a man leaving the camp infirmary claiming to be Reck.^[7] The story would be later recanted in his book Goethe in Dachau.^[8] This has cast the exact date and time of his death into some debate however very few believe the man Rost encountered was Reck.
