‎---- EDITION ORIGINALE ---- BEL EXEMPLAIRE ---- "Encke was professor and director of the Seeberg observatory. He demonstrated that the comet discovered by Pons, which was later called Encke's comet, had a period of scarcely four years and that it had been observed repeatedly. Prior to this only a few comets with elliptical orbits and much longer periods had been known... Encke's lectures were nevertheless influential, since a whole generation of astronomers, including Galle, F.F.E. Br¥nnow, B.A. Gould, K.N.A. Kruseger, W.J. Förster, F. Tietjen and K.C. Bruhns were among his disciples... Many of his writings were brought together as Astronomische Abhandlungen, 3 vols". (DSB IV pp. 369/370)**1971/L3‎
