Vogt studied medicine and chemistry in Giessen from 1833 (under Justus von Liebig). He was a member of the Giessen fraternity, which was persecuted by the authorities for its political tendencies. After its dissolution, he joined the resulting Corps Palatia Giessen. In 1835 he helped a fellow student to escape from the political police and was also forced to leave Germany. - Cover somewhat damaged. R
