Josef Ospelt, to the son of Julius Caesar and his mother Mary Seger, was born in Vaduz on 9 January 1881.

After having attended a country school in Vaduz, he began working as a government councillor under Governor of Liechtenstein Carl von In der Maur.

[1][2] In 1918, Ospelt was a founding member of the Progressive Citizens' Party and was later elected chairman and long-time manager of the newspaper Liechtensteiner Volksblatt.

[6] Under the successor government under Gustav Schädler, Ospelt faced criticism from his term due to his ties with Johann II and former Governor Josef Peer.

He was among the founding members of the Historical Society in Liechtenstein, which he headed from 1928 to 1955 as chairman and for many years on the Board of the Vintners of Vaduz.
