     Dr phil hc*
     (From 1811 on Encke studied mathematics in Goettingen as pupil of C.F. Gauss. In May 1816 he moved to Seeberg near Gotha to work as observer at the observatory there. In 1822 he was promoted Director of that observatory and in 1825 followed a call to be the Director of the Observatory at Berlin. He supervised the new construction of the observatory from 1832 -35. In 1844 he became ordinary professor at the University of Berlin and was allowed to lecture without receiving a doctorate. Closest to being his advisor in becoming a professor was therefore Carl Friedrich Gauss.
