Vogt was born on 19 July 1906 in Balzers as the son of farmer Josef Kaspar and Magdalena Theresia Gstöhl as one of six children.

[3] In 1937, he was the defending lawyer of Carl Freiherr von Vogelsang after he publicly denounced Jews living in Liechtenstein and sent numerous letters detailing them to officials in Nazi Germany.

[7][8][9] As a result, Vogt was appointed the Deputy Prime Minister of Liechtenstein under Josef Hoop, replacing Anton Frommelt.

[1] He was an outspoken supporter of National Socialism throughout his premiership as deputy prime minister and used his position to push relevant demands through Hoop, assisted by the party's president, Otto Schaedler, who agitated for a more cooperative stance towards Nazi Germany.

[1][13] Shortly after the war, an indictment was pressed against Vogt due to his ties to Germans intelligence, but the case never went to trial since the Patriotic Union threatened to end the coalition government.
