Summary of the lecture
In 1975, Pakistani metallurgist Abdul Khan, educated in Delft, returned to his homeland. Thanks to contacts with Urenco in Almelo, he had been able to steal secret ultracentrifuge technology that enabled him to produce highly enriched uranium in Kahuta. Not only did Khan provide Pakistan with an atomic bomb, he also sold his knowledge to "rogue states" North Korea, Iran and Libya. Meanwhile, in the Netherlands, whistleblower Frits Veerman fought in vain for rehabilitation. He had reported Abdul's spying at the time but was scorned, fired and thwarted by his employer and the BVD. 'If Iran throws a bomb on Israel,' Veerman said, 'it will have "Made in Holland" written on it.'

Information about the speaker
Dirk van Delft (1951) studied physics in Leiden. He stood in front of the classroom, was chief scientist at NRC Handelsblad and director of Rijksmuseum Boerhaave. At Leiden University, he is emeritus professor of 'Material heritage of the natural sciences'. Since his retirement in 2018, he has been a visiting fellow at the Institute Lorentz. In 2015, he obtained his PhD with Heike Kamerlingh Onnes. A biography. With Ton van Helvoort, he wrote Images without parallel: the electron microscope from Ernst Ruska to Ben Feringa (2018) and with Frits Berends the biography Lorentz: celebrated physicist, born conciliator (2019). Biographies of astrophysicist Henk van de Hulst (2020) and Antoni van Leeuwenhoek (2022) followed. In 2021, he published Splijtstof: how whistleblower Frits Veerman unmasked nuclear spy Abdul Khan and the Pakistani bomb came after all.
