Willi Lenz (1894–1945): The “Doctor” of Kulmhof

Willi Lenz, a Schutzpolizei officer born in 1894, was one of the most brutal perpetrators at the Kulmhof (Chełmno) extermination camp. Known as the “Doctor,” he supervised forced laborers in the forest camp, personally shot those who were exhausted or survived the gas vans, and later used his experience in operations to exhume and burn the bodies of Nazi victims. Returning to Kulmhof in 1944, he continued killing prisoners during the liquidation of the Łódź Ghetto. In January 1945, while helping to execute the camp’s remaining Jewish prisoners before the German retreat, Lenz was killed during their resistance in the granary.

1942-05-16 / The Becker Letter on Gas Vans: “The gassing is generally not carried out correctly … the persons being executed die of suffocation”

On May 16, 1942, SS-Untersturmführer August Becker submitted a report to the head of RSHA department II D, Walther Rauff, on his inspection of the operation of the homicidal gas vans at the Einsatzgruppen. Becker noted that the vehicles had become widely recognized, “that not only the authorities but also the civilian population referred to them as ‘death vehicles’ as soon as one of them appeared”. He also observed “various units have their own men unload the vehicle after the gassing,” and warned the commanders of “what enormous psychological and physical harm this work can cause to the men.” He states that “the gassing is generally not carried out correctly,” as drivers “consistently apply full throttle,” with the result that victims “die of suffocation.”

1943-04-19 / The Short Version of the Korherr Report: “European Jewry has probably lost almost half of its total population”

On April 19, 1943, SS statistician Richard Korherr submitted a shortened version of his Korherr Report – the SS’s statistical account of the “Final Solution of the European Jewish Question” – to the personal staff of Reichsführer-SS Heinrich Himmler, for presentation to Adolf Hitler. In the report, Korherr estimated that “the reduction of Jewry in Europe from 1937 to the beginning of 1943 is to be estimated at 4½ million” and noted that “only part of the deaths of Soviet-Russian Jews in the occupied eastern territories could be recorded, while those in the rest of European Russia and at the front are not included at all.” He concluded that “European Jewry since 1933 has probably lost almost half of its total population,” of which “only about half has flowed to other continents.”

1943-04-10 / Himmler’s Order to Sanitize the Korherr Report: “At No Point Should There Be Any Mention of Special Treatment of the Jews”

In April 1943, Heinrich Himmler ordered changes to the Korherr Report, the SS’s statistical account of the “Final Solution” he considered as quite good “for camouflage purposes”. A letter dated April 19, 1943 instructed that the term “special treatment of the Jews” be removed from the report. The euphemism “passed through the camps in the General Government and the camps in the Warthegau” was to be used to denote the death toll from the extermination camps at Bełżec, Treblinka, Sobibór, and Kulmhof (Chełmno).

1943-04-09 / Himmler’s April 1943 Letter on the Korherr Report

A brief letter written by Heinrich Himmler, Reichsführer-SS, on April 9, 1943, to Ernst Kaltenbrunner, Chief of the Security Police and SD, makes direct reference to the so-called Korherr Report – a statistical analysis compiled by Richard Korherr, the SS’s chief statistician, on the progress of the “Final Solution”. In it, Himmler acknowledges the report’s value as “material for possible later times” and, above all, “for camouflage purposes”. At the same time, he orders that the report must not be published or circulated further. Himmler closes the letter by stressing his overriding concern that “what remains most important to me is that Jews are now being shipped off to the East as much as is at all humanly possible.”

1943-04-28 / The Korherr Report: Nazi Statistics on the “Final Solution” Through Early 1943

This post reproduces the so called Korherr Report, a statistical report on the “Final Solution of the European Jewish Question” up to 1943 and its accompanying cover letter from April 1943. Authored by SS statistician Richard Korherr for Heinrich Himmler, the report presents – through a veneer of euphemism and bureaucratic precision – the numerical decline of European Jewry via excess of deaths over births, emigration, deportation and so-called “evacuations” and “special treatement”. The report concludes that “European Jewry since 1933 … likely lost nearly half of its population”. A substantial portion of this loss is attributed to 1,274,166 Jews “processed through camps in the General Government” (i.e. Belzec, Treblinka, Sobibor), 145,301 Jews “processed through camps in the Warthegau” and 633,300 Jews “evacuated in the Russian territories”.

1942-06-02 / SS-Officer Just’s Memo on Gas Vans: “97,000 have been processed using 3 deployed vehicles”

Memo dated June 5, 1942, authored by SS-Hauptsturmführer Willy Just of RSHA office II D 3 a (Motor Vehicle Department of the Security Police) on technical modifications to the gas vans used in mass killing operations. Just reports that “since December 1941 97,000 have been processed using 3 deployed vehicles, without any defects occurring in the vehicles” and “the known explosion in Kulmhof (Chełmno) is to be considered an isolated case due to an operating error”. He proposes the following “technical modifications to the special vehicles currently in operation and those under production”, among other things ventilation slots on the upper rear wall to allow “a rapid inflow of CO without causing overpressure”. The proposal was reviewed by Walther Rauff, head of the Motor Vehicle Department, on June 10, 1942. He approved the implementation of the modifications on a prototype vehicle.
