Celebrating engineering is quite tantamount to celebrating architecture, given that before modernity drew a line between the two disciplines, they were really one same thing. So it is that Arquitectura Viva, using anniversaries, pays tribute to three great engineers: Jorge Juan, Agustín de Betancourt, and Gustave Eiffel. The first was a mariner and scientist in Spain of the Enlightenment, and in observance of the 250 years that have passed since he died, an exhibition at the Naval Museum in Madrid looks back on his career, from his explorations with Charles Marie de La Condamine to measure the Meridian to the founding of the Spanish Royal Observatory, passing through the mission of industrial espionage in London shipyards and the successful modernization of the Spanish Armada. No less adventurous and fruitful was the life of Agustín de Betancourt, who devised early steam engines and was a Major General of the Russian Empire, the architect of great public works, and the founder in 1802 of Madrid’s School of Civil Engineering, the current director of which has organized a lecture series to commemorate the bicentennial of his demise. And in line with the death centenary of Gustave Eiffel, France will abound in exhibitions revolving around him, arguably the most famous engineer of what was the quintessential century of engineering, who here in Spain built pioneering structures like the Hacho Bridge.[+]
