Wacław Struszyński
Wacław Struszyński (; 1904–1980) was a Polish electronics engineer who made a vital contribution to the defeat of U-boats in the Battle of the Atlantic. He designed an exceptional radio antenna which enabled effective high frequency (HF) radio direction finding systems to be installed on Royal Navy convoy escort ships. Such direction finding systems were referred to as HF/DF or Huff-Duff, and enabled the bearings of U-boats to be determined when the U-boats made high frequency radio transmissions. Early life Struszynski was born in Wieruszów near Łódź (now in Poland) in 1904. He spent his youth in Moscow, but the family returned to Poland in 1918. He received his master's degree in Engineering (Dipl. Ing.) at the Warsaw University of Technology in 1929, and joined the Polish State Telecommunication Establishment, where he became head of the Direction Finding Division. When Poland was invaded in 1939, he was evacuated from Warsaw, and reached England in 1940. Struszynski's father was chemist Professor Marceli Struszynski of the Warsaw University of Technology. During the Second World War, he worked with the Polish resistance, and analyzed the fuel used in the V2 rocket. Career World War II Radio direction finding and U-boat tracking In World
