Hayit was born in the city of Namagan in 1916.
He was drafted into the Soviet Army during World War II and was taken prisoner by Nazi troops before joining Germany's anti-Bolshevik Turkestan Legion. He remained in West Germany after the war.
Historian Qakhramon Rajabov, a member of Uzbekistan's Academy of Sciences, says that despite a wartime past that earned Hayit the epithet of "traitor" in the official Soviet press, he never got any form of official recognition in post-Soviet Uzbekistan.
"It is a pity that not a single of his books has even been published in his Uzbekistan since independence," said Rajabov. "Yet everyone knows very well the accusations that were brought against him during the Soviet period."
In 1992, Hayit went on a visit to his native country. But Uzbek authorities asked him to leave after a few days, citing protests made by World War II veterans.
Hayit will be buried in Cologne on November 7.
