Dan Ert, alias of Dan Aerbel, was born on February 28, 1937, in Gentofte, Denmark, to a Jewish family. He held Danish citizenship and carried a Danish passport under the name Dan Ert. Described as a Danish-Israeli businessman, he was married with three children as of 1973 and lived in various countries. A member of Mossad, Ert played a key role in Operation Plumbat (1968), serving as president of the fictitious Liberian firm Biscayne Trader's Shipping Corporation, which purchased the cargo ship Scheersberg A for the uranium theft. In the Lillehammer Affair (1973), he was part of a 15-member Mossad team under Operation Wrath of God, seeking revenge for the 1972 Munich Olympics massacre. Arrested in Norway shortly after the July 21 mistaken assassination of Moroccan waiter Ahmed Bouchikhi (or Bouchiki), wrongly identified as Black September operative Ali Hassan Salameh, Ert had rented a getaway car under his real name alongside Marianne Gladnikoff, leading to arrests due to unchanged license plates. He suffered extreme claustrophobia during interrogation and confessed to Mossad involvement in Operation Plumbat, exposing safe houses, agents, phone numbers, and hints at Israel's nuclear program (which Norway kept silent about). One of six convicted Mossad agents, he served approximately 22 months of a 1-5.5 year sentence before release and deportation to Israel in 1975. In 1977, aged 40, he was confirmed as an Israeli intelligence agent linked to uranium shipping. As of 2023, he was the subject of a Haaretz article where the agent 'breaks silence' on the Lillehammer fiasco.
