The Israeli response was Wolfgang Lotz:
He also composed a list of German scientists who worked for the Egyptians and in September 1964 he sent letter bombs to some of them, in an attempt to induce them to cease their work. Lotz'z letter bombs killed some civilians and their effects were deemed limited.
Previously, in 1962, Israel had already been active: due to the fact that German scientists and technicians, formerly employed in Nazi Germany's rocket program, were developing rockets for Egypt at a military site known as Factory 333. The rockets it was claimed being developed were programmed to use a radioactive waste.
The main tactics employed by Israel against the scientists were letter bombs and abductions. Their families were threatened with violence to persuade the scientists to return to Europe. Mossad provided a small operational unit, headed by future Israeli Prime Minister Yitzhak Shamir, but since it lacked an operational division at that time it mainly used units from the Shin Bet to carry out the attacks.
A parcel sent to rocket scientist Wolfgang Pilz exploded in his office when opened on 27 November 1962, injuring his secretary.
A parcel sent to the Heliopolis rocket factory killed 5 Egyptian workers.
A pistol was fired at a West German professor in the town of Lörrach who was researching electronics for Egypt. The bullet missed and the gunman escaped by car.
Heinz Krug, 49, the chief of a Munich company supplying military hardware to Egypt disappeared in September 1962 and is believed to have been murdered. Krug was director of an Egyptian dummy company operating out of Munich that was involved in a building missiles in Egypt.
Hans Kleinwachter, a rocket scientist who worked on the V2 project was targeted in February 1963, but the assassination attempt failed due to a weapon malfunction.
Others targeted as threats to Israel include Colonel Mustafa Hafez, Colonel Salah Mustafa, the Munich murderers and others.
Is Iran the current object?
