[1] He was born as a member of the Lahovary family, an old noble Boyar family to Nicolae Lahovary (1816–1883), who served as Senator and his wife, Eufrosina Iacovache (1825–1884) from Râmnicu Vâlcea (maybe related to the House of Lackovic).

After being tutored by private teachers, he moved to Paris to teach.

Lahovary was then appointed the Minister of Justice and served in this capacity for two terms: from April 20 through December 14, 1870, and October 25, 1873, until March 30, 1876.

The Alexandru Lahovari National College in Râmnicu Vâlcea is named after the diplomat.

[2] A square [ro] in central Bucharest is named after him; a statue of Lahovary [ro] (built by sculptor Antonin Mercié in 1901) is in the middle of the square.
