In 1917 Low and his team also invented the first electrically steered rocket (the world's first wireless, or wire-guided rocket), almost an exact counterpart of the one used by the Germans in 1942 against merchant shipping. Low's inventions during the war were to a large extent before their time and hence were under-appreciated by the Government of the day, although the Germans were well aware of how dangerous his inventions might be. In 1915 two attempts were made to assassinate him; the first involved shots being fired through his laboratory window in Paul Street; the second attempt was from a visitor with a German accent who came to Low's office and offered him a cigarette, which upon analysis contained enough strychnine chloride to kill.
