Jerzy Witold Różycki (pronounced [ˈjɛʒɨ ruˈʒɨt͡ski] ; July 24, 1909 in Vilshana, Ukraine – January 9, 1942 in Mediterranean Sea, near the Balearic Islands) was a Polish mathematician and cryptologist who worked at breaking German Enigma-machine ciphers before and during World War II.

Life

Różycki was born in what is now Ukraine, the fourth and youngest child of Zygmunt Różycki, a pharmacist and graduate of Saint Petersburg University, and Wanda, née Benita. He attended a Polish school in Kiev before moving with his family to Poland in 1918. In 1926 he completed secondary school at Wyszków on eastern Poland's Bug River.

Różycki studied mathematics from 1927 to 1932 in western Poland, at Poznań University's Mathematics Institute, graduating with a master's degree on February 19, 1932. He would later earn a second master's degree from Poznań University, in geography, on December 13, 1937.

In 1929, while still a student, Różycki, proficient in German, was one of twenty-odd Poznań University mathematics students who accepted an invitation to attend a secret cryptology course organized at a nearby military installation by the Polish General Staff's Cipher Bureau, headquartered in Warsaw.

From September 1932 Różycki served as a civilian cryptologist with the Polish General Staff's Cipher Bureau, housed till 1937 in Warsaw's Saxon Palace. He worked there together with fellow Poznań University mathematics alumni and Cipher Bureau cryptology-course graduates Marian Rejewski and Henryk Zygalski.

After Rejewski had reconstructed the German military Enigma machine in December 1932, Różycki and Zygalski likewise worked at ongoing development of methods and equipment to exploit Enigma decryption as a source of intelligence. Różycki invented the "clock" method, which sometimes made it possible to determine which of the machine's rotors was at the far right, that is, in the position where the rotor always revolved at every depression of a key. Różycki perished in the Mediterranean Sea on January 9, 1942, while returning to the Cadix center, near Uzès in southern, Vichy France, from a stint at its branch office at the Château Couba on the outskirts of Algiers. His passenger ship, the Lamoricière (ocean liner) [fr],[1] sank in unclear circumstances near the Balearic Islands. Fellow victims of the disaster, among the 222 passengers killed, included Piotr Smoleński and Capt. Jan Graliński, of the prewar Cipher Bureau's Russian section, and a French officer accompanying the three Poles, Capt. François Lane.

Family

In 1938, aged 29, Różycki had married Maria Barbara Mayka. Their son, Janusz Różycki, born May 10, 1939, would complete his studies at Warsaw's Academy of Fine Arts and go on to be a member of the Polish fencing team that won a silver medal at the 1964 Tokyo Olympics.

Rememberance and honours

2007 monument to cryptologists Rejewski, Różycki, and Zygalski in front of the Imperial Castle in Poznań

On 21 February 2000, he was posthumously awarded by President of the Republic of Poland Aleksander Kwaśniewski with the Grand Cross of the Order of Polonia Restituta for outstanding contributions for his homeland.[2]

In 2007, the Statue of Cryptologists was unveiled in front of the Imperial Castle in Poznań. It commemorates the three mathematicians and cryptologists (Rejewski, Różycki and Zygalski) affiliated with the University of Poznań who broke the Enigma code and helped end the Second World War.

In 2009, the Polish Post issued a series of four commemorative stamps, one of which included a picture of Różycki alongside fellow cryptologists Marian Rejewski and Henryk Zygalski.[3]

In 2014, Różycki (together with Rejewski and Zygalski) was awarded the prestigious IEEE Milestone Award by the Institute of Electrical and Electronics Engineers in recognition of achievements that have changed the world.[4]

In 2014, a commemorative plaque in Polish and English dedicated to him and his two colleagues was officially unveiled in front of the Mathematical Institute of the Polish Academy of Sciences in Warsaw.

In 2018, a bench dedicated to Różycki was unveiled in a park in the town of Wyszków where he attended high school.[5]

Różycki and colleagues were the heroes of Sekret Enigmy (The Enigma Secret), a thriller movie about the Poles' solution of the German Enigma cipher. Late 1980 also saw a Polish TV series with a similar theme, Tajemnice Enigmy ("The Secrets of Enigma").[6]
