According to the Yad Vashem Holocaust Martyrs' and Heroes' Remembrance Authority in Jerusalem, "[a]ll the serious research" confirms that between five and six million Jews died. Early postwar calculations were 4.2 to 4.5 million from Gerald Reitlinger; 5.1 million from Raul Hilberg; and 5.95 million from Jacob Lestschinsky. In 1986 Lucy S. Dawidowicz used the pre-war census figures to estimate 5.934 million. Yehuda Bauer and Robert Rozett in the Encyclopedia of the Holocaust (1990) estimated 5.59–5.86 million. A 1996 study led by Wolfgang Benz suggested 5.29 to 6.2 million, based on comparing pre- and post-war census records and surviving German documentation on deportations and killings. Martin Gilbert arrived at a minimum of 5.75 million. The figures include over one million children.
