Louis Hector Leroux (1829–1900) was a French painter born in Verdun and active until his death in Angers. He worked within the academic style, with critics often affiliating him with the Néo-Grecs movement. His artistic practice was rooted in the prevailing classical traditions of 19th-century French art, emphasizing historical and mythological subjects.
Leroux specialized in meticulously researched paintings of ancient Rome, particularly focusing on depictions of women. He developed a significant body of work centered on Vestal virgins, a series comprising some thirty paintings executed throughout his career. His compositions reflect a precise approach to historical detail and classical iconography.
Leroux's artistic legacy includes his daughter, Laura Leroux-Revault, who also pursued a career as a painter. His work contributed to the academic discourse on classical antiquity in French art during the latter half of the 19th century.
