魏登
Born in Floss, Bavaria in 1911, Baer grew in a Protestant family. In 1925 he moved to Weiden in der Oberpfalz where he performed a three-year apprenticeship spell as pastry chef. After completing his vocational training, Baer toured Bavaria for several years as a journeyman. Eventually, in winter of 1932, he returned to the pastry company of his apprenticeship, and worked there until he resigned in March 1933.
