1896年,洛维被任命为巴黎天文台台长,他对该机构进行了重组,并新组建了一个物理天文学部。1910年他发表出版了与皮埃尔·皮瑟(英语:Pierre Puiseux)用10年时间完成的一套由1万幅照片组成的《月球摄影地图集》(L’Atlas photographique de la Lune),该著作成为半个多世纪来月球地理的权威理论。他还积极参与天图成像项目。月球上的洛威陨石坑以及小行星253 梅西尔德就是分别以他和他妻子的名字命名的。
^According to investigations by Anneliese Schnell (Maurice Loewy and the equatorial Coudé in Vienna,Astronomische Nachrichten, Vol. 330, Issue 6, p. 552-554 [1] (页面存档备份,存于互联网档案馆)), he was born in Vienna, because this city is, e.g., given in a French translation of his birth certificate. Vienna as his birthplace is also given in the obituaries, in most of the large encyclopedias, and in other sources. Some sources indicate, obviously wrongly, Bratislava or Mariánské Lázne as his place of birth.
