It gives me great pleasure to present an essay written by my compatriot, Dr. Kevin MacKeown (now at the Unversity of Hong Kong) on the life and work of the Danish astronomer, Dr. William Doberck (1852-1941), who, amongst other things, dedicated his professional career to double star astrometry.
Most significant for me was his spell at Markree Observatory, Co. Sligo, Ireland (my homeland), where he used a magnificent 13.3 inch refractor, with a lens fashioned by Robert A. Cauchoix of Paris, which was privately owned by a wealthy British gentleman, Edward J. Cooper. There the telescope was used to catalog 60,000 stars. After leaving the west of Ireland, Doberck moved the telescope to Hong Kong Observatory, where he served as its first director between 1883 and 1907.
