While at the University of Berlin, Schur briefly worked with von Auwers on understanding observations made by English astronomer
James Bradley. His work throughout this period was mainly focused on the
apparent magnitude of
variable stars and on the determination of
comet orbits. created by Schur in 1894|alt= On Easter 1886 Schur was appointed to the University of Göttingen as Professor of Practical Astronomy and Director of the
Göttingen Observatory. Throughout 1887/1888 he led a complete redevelopment of the observatory in which "almost only the walls remained untouched." Major projects included the renewal of the main hall's roof and the replacement of the outdated dome with one manufactured by
Grubb in
Dublin, Ireland. In 1899 he published another catalogue, this time of comets and
minor planets observed by
Wilhelm Olbers from 1795 to 1831. For the 150th anniversary of the
Göttingen Academy of Sciences in 1901 he wrote a historical overview of the development of astronomy in the
Kingdom of Hanover and neighbouring areas. At the beginning of 1901 Schur began exhibiting symptoms of severe stomach cancer and his health began to rapidly deteriorate. He was left housebound and could only partially continue his work. He failed to recover and died in the evening hours of 1 July 1901. == Personal life ==
