After his graduation, Siebel worked for the Social Research Center of Dortmund. In 1964, he was appointed a lecturer at the Ruhr University at Bochum. In 1965, he was appointed Professor of Sociology at the University of the Saarlands in Saarbrücken.

Siebel was raised an Evangelical Protestant and converted to Catholicism a short time before Vatican II. As a Conservative Christian, he became involved with the Catholic Traditionalist movement resisting the adoption of the Modernist ideas into Catholicism as a result of the Aggiornamento and Vatican II.
The French Traditionalist priest, George de Nantes wrote in his The Catholic Counter-Reformation in the XXth Century, #220, June 1989, page 20, para 1 & 2 that Wigand Siebel and his followers teach that, with the Modernist apostasy, the Catholic Papacy has ceased to be or that it has come to an end, a teaching which contradicts Catholic teaching that is strongly emphasised.
