The second Prix de Rome in Architecture was awarded in 1845 to a Frenchman who would eventually pivot from drafting structures to documenting the remote landscapes of Africa and the Middle East. Pierre Trémaux balanced a career as a professional architect with the rigorous, early pursuit of ethnographic photography and speculative scientific research.
Architectural Education and Early Practice
Born in Charrecey in 1818 to Jean-Marie Trémaux and Claudine Renaudin, Trémaux began his formal training at the Beaux-Arts de Paris in 1840. By 1845, he secured professional recognition through the Prix de Rome. His technical background led to employment at the Schneider establishments in Le Creusot, where he focused on urban development and large-scale industrial infrastructure, including interest in the construction of the Suez Canal.

Trémaux launched two major expeditions between 1847 and 1854. His first journey took him through Algeria, Tunisia, Upper Egypt, Sudan, and Ethiopia, where he captured early photographic images of these territories. A second trip followed in 1853 and 1854, expanding his documentation to include Libya, Asia Minor, Syria, and Greece. These voyages resulted in the production of diverse visual media, such as salted paper prints, engravings, and lithographs, which were later published under the support of the French government.
Scientific Theory and Publications
In 1865, Trémaux published Origine et transformations de l'homme et des autres êtres, a work that gained attention at the 1867 Universal Exhibition in Paris. The text proposed an evolutionary theory attributing human racial differences to geological and soil-based factors, alongside the concept of orthogenesis. His broader bibliography includes several volumes documenting his travels, most notably the Voyages series released between 1852 and 1862, which combined his photography with detailed geographical and architectural analysis.
