Antonín Sum

Antonín Sum was a prominent Czech politician and secretary to Jan Masaryk, the son of Tomáš Garrigue Masaryk, the founder of Czechoslovakia. He played a significant role in preserving historical documents related to the Masaryk legacy, including a mysterious letter sealed by Tomáš Masaryk in 1937. Sum was later imprisoned for high treason during the Stalinist regime in Czechoslovakia, but he continued to advocate for the return of important historical documents to the nation until his death in 2006.
