(b ?Seville, 1812; d ?Seville, 1882). Photographer active in Spain. He is particularly known for his calotypes, mainly views of Seville. The city boasted a large number of photographers using the calotype process, of whom he was one of the most notable. By 1851, a decade after he announced his ‘heliographic’ views (as he called these early calotypes), he was making daguerreotypes and wet-collodion glass-plate negatives, as well as calotype positives. Almost as soon as stereoscopic glass plates were devised, Leygonier announced that he had an assortment of these. Even with all his innovative modern methods, he continued to practise the calotype process at least until 1859. Examples of his calotypes include two views of the Patio de las Doncellas in the Alcázar of Seville (Austin, U. TX, Ransom Humanities Res. Cent.). Also active as a teacher of photography, his forte was his rapid assimilation and commercial diffusion of the newest photographic media.
