Grégoire. Aimé, Paul. 36 ans, né à Bruxelles (Belgique). Accordeur de piano. Anarchiste. 2/3/94. 1894

Alphonse Bertillon's 1894 photograph, "Grégoire. Aimé, Paul. 36 ans, né à Bruxelles (Belgique). Accordeur de piano. Anarchiste. 2/3/94.", is a classic example of his innovative photographic system for criminal identification. Bertillon's anthropometric method, also known as Bertillonage, involved taking a series of eleven measurements of the body and capturing eleven photographs of the individual from different angles. The stark, frontal portrait of the subject, an anarchist piano tuner from Brussels, highlights Bertillon's focus on precise detail, which was crucial for his pioneering approach to criminal identification.
