It was discovered on 25 November 1933, by French astronomer Louis Boyer at the North African Algiers Observatory, Algeria, and named after the discoverer's niece.
[14] In January 2002, a rotational lightcurve of Andrée was obtained from photometric observations by French amateur astronomer Laurent Bernasconi.
Lightcurve analysis gave a well-defined rotation period of 5.178 hours with a brightness variation of 0.27 magnitude (U=3).
[10] In October 2004, a concurring lightcurve with a period of 5.18366 hours and an amplitude of 0.23 was obtained by French astronomers Cyril Cavadore and Pierre Antonini (U=3).
