Stephen Sándor was born on 26^th November 1914, in Szolnok in Hungary. He was the eldest of three children, his father worked on the railways, and his mother stayed at home. Stephen's parents were very religious and passed that spirit down to their children.

Stephen's friends admired him as he was often happy, but serious and gentle, in equal measures. He was also an example for his younger brothers, and often helped lead them in prayer and studying.

Every day, he would serve Mass with the Franciscans. He would often read the Salesian Bulletin, and this is how he got to know Don Bosco. After speaking with his spiritual director and having to convince his parents, he was accepted at the Clarisseum in Budapest. He was an aspirant there for two years, completing a course on printing at the Don Bosco printery. He then began his novitiate; however, this was disrupted by being called by military service.

He restarted his novitiate upon his return and made his first vows in 1940. He then began teaching technical courses. He also fostered Young Catholic Workers and assisted in the Oratory. However, in 1942, he was called back to the military front line and acted as a correspondent and telegrapher. Upon the end of the war, he was held in captivity by the American army and was released in 1945.

When he returned, he went back to work in the press at the Clarisseum. He helped to rebuild society, both materially and morally, especially poor young people. During this time, he made his perpetual profession on 24^th July 1946. He gained the title of Master Printer after passing his exam in 1948.

In 1950, the state made the operation of religious orders illegal, which affected the Salesians in Hungary. He worked as a vestryman, but also worked with young people in secret. Some of those young people were conscripted and some stayed in touch with Stephen. But the state heard of the work that Stephen was doing with the Young People, causing Stephen to have to change his name, and arrangements being made for him to leave Hungary. However, Stephen felt that he could not leave the young people and decided to return to Budapest.

Eventually, Stephen was arrested, and while in prison, he was beaten several times with the aim of confessing to his crimes. Eventually he was put on trial, in secret, and sentenced to death. Stephen as well as three others were killed on 8^th June 1953. Stephen is recognised as a martyr by the Catholic Church and was beatified on 19^th October 2013 by Cardinal Angelo Amato.
