Jean-Baptiste Lassus
French architect (1807–1857)

Jean-Baptiste-Antoine Lassus (19 March 1807 – 15 July 1857) was a French architect who became an expert in restoration or recreation of medieval architecture. He was a strong believer in the early Gothic architecture style, which he thought as a true French and Christian tradition, and was opposed to the classical Graeco-Roman styles promoted by the academic establishment.

Why this record matters
“Jean-Baptiste Lassus” is worth following because a concise public description often conceals a longer documentary argument. Here, Jean-Baptiste, Lassus and French provides the most credible route into that argument.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Jul 30, 2026. The linked authority identifier is Q3163757. VIAF identifies the subject as 68931540. The Library of Congress control number is n81131840. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1807, 1857, 1823 and 1828.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
