Abstract
ON May 29 the centenary occurs of the birth of the eminent Swedish astronomer, Hugo Gylden, who for many years was director of the Stockholm Observatory. Gylden was the son of the professor of Greek at the University of Helsinki, and he received a careful training under his father. He also studied at Gotha and Leipzig, and at the former place came under the influence of Hansen. At the age of twenty-one he entered Pulkowa Observatory, and there, under Struve, began his investigations on the orbits of comets and planets. Nine years later he was called to Stockholm as director of the observatory and astronomer to the Royal Academy of Science, and he retained these appointments until his death on November 9, 1S96. His papers exceeded two hundred in number, and related to the motion of planets and comets, the rotation of the earth, stellar parallax, refraction, mathematical analysis, cosmogony and other subjects. In 1879 he succeeded Secchi as a corresponding member of the Paris Academy of Sciences. He was made an associate of the Royal Astronomical Society, to which an obituary of him was contributed by his most famous pupil,. Backlund.
