Biografic note

Józef Stanisław Kosacki, son of Antoni and Aleksandra née Roszkowska was born in 1909 in Łapy town. His father was an engine driver. He passed secondary school certificate examinations in Częstochowa; in 1933 he graduated the Electric Department of Warsaw University of Technology. Having finished his studies, Kosacki took part in military training at the Cadet School for reserve engineers in Modlin town (September 1933 – July 1934) and he practised as a cadet platoon leader in the electrochemical battalion in Nowy Dwór (July – September 1934). One year later, following reserve exercises which took place in the same unit, he was promoted to Second Lieutenant. He began his work at the State Telecommunication Institute as Head of Amplifier Department. He worked there up to outbreak of the War. On September 4th, 1939 he joined the Army and during the September campaign he served in the Technical Group of the Special Communication Unit. During the Warsaw defence this group activated Warsaw II radio station. It is via this radio station that the Mayor of Warsaw Mr. Starzyński gave his speeches up to the downfall of the city. Kosacki was interned in Hungary and after the escape from the camp he reported in Paris into the Polish Armed Forces. After the downfall of France he went to England. He served in the Communication Training Centre up to 1943 and later on, until the end of World War II he worked at the Military Communication Factory in London as a scientist-constructor and the head of Control Department.

In 1941 an accident happened which moved the Lieutenant deeply: the patrol of the 14th Regiment of Polish uhlans from the 10th Armoured Cavalry Brigade (so-called “Black Brigade”, later the 1st Armoured Division) under the command of Captain Górski fell into anti-landing mines on the beach in Arbroath in Scotland. This tragic inspired an idea which took the next three months of tests and improvements and eventually resulted in a prototype. He himself tested the prototype using real mines, buried in the ground. The experiment turned out to be a success. In the same year the British Ministry of Procurement announced a contest for a mine detector. Seven similar devices were entered. Lieutenant Kosacki’s concept won.
The production was initiated in a record time. For the first this mine detector was used in the battle of El Alamein (North Africa) in 1942 . Until the WWII ended, the mine detector was manufactured in a few, somewhat different versions, among which „Polish Mine Detector Mark 2” was the most renowned. The mine detector prototype (the same which won in the contest) can be found in the Institute`s Room of Tradition, thanks to the kindness and generosity of the Inventor`s son - Mr. Jan Kosacki.

Józef Kosacki returned to Poland in the spring of 1947 and began his work in the State Telecommunication Institute at the same position as before the War outbreak, when he was the Head of the Department of Impulse Technology. It is in this department that the first in Poland impulse systems were constructed.
The next chapter in Józef Kosacki’s professional career was nuclear electronics  the title of an associate professor (1955), and then professor (1964, Military Academy of Technology (WAT)). Since 1956 he has worked in the Institute of Nuclear Investigation (IBJ) in Świerk town not far from Warsaw, where he was the Head of Electronics Department from 1958 up to 1976. In 1976 he retired. In those days under his leadership innovative projects were developed, e.g. multi-channel amplitude and time analysers.

Throught his scientific and professional career Professor Kosacki witnessed and participated in the development of the entire field of electronics – from tube systems to computer systems. While working for the IBJ, he was also a faculty member of the Military Academy of Technology ,as well as University in Warsaw and University of Technology in Warsaw, where he was the Chair of the Institute´s Council of Teleelectronics. He was conferred the associate professor title and then the title of a professor in the Military Academy of Technology. He promoted some post-graduate students in both IBJ and WAT.
His war contributions and his service were nor forgotten. He was decorated with the Officer Cross of the Rebirth of Poland (1959), twice with Silver Cross of Merit (1942, 1954), British Defence Medal (1946) and twice Medal of the Polish Army (1946, 1947) apart from ministerial decorations. When he died in 1990, he was buried with military honours. His resting-place is the Bródno Cemetery in Warsaw.
