Longomontanus

1562-1647

Danish astronomer, also known as Christian Severin, who was Tycho Brahe's only disciple. Upon his master's death Longomontanus assumed responsibility for selecting and integrating Tycho's data into a coherent account of planetary motions and presenting this work in a systematic treatise. His task was brought to fruition in Astronomia danica (1622), which was enthusiastically received by the astronomical community. The prestige attached to his work saw it through two reprintings despite the appearance of Johannes Kepler's Tabulae Rudolphinae in 1627.
