“Who was Carlos Ibáñez e Ibáñez de Ibero?” That’s probably the question on your mind as you stand before this memorial. Let’s unravel the story of this remarkable Spanish general and geodesist. The Memorial General Ibáñez de Ibero stands as a tribute to a man who significantly shaped the world of metrology and geodesy.
Carlos Ibáñez e Ibáñez de Ibero was born in Barcelona in 1825. His full name reflected Spanish tradition. It combined his father’s and mother’s surnames. He was also known as the Marquis of Mulhacén.
Ibáñez de Ibero’s career was diverse. He was a divisional general in the Spanish Army. More significantly, he excelled in geodesy. Geodesy is the science of accurately measuring and understanding Earth’s geometric shape, orientation in space and gravitational field.
Spain adopted the metric system in 1849. The Spanish Royal Academy of Sciences urged the government to create a large-scale map. In 1852, Ibáñez was appointed to lead this huge task.
Ibáñez recognized the need for specialized equipment. He collaborated with Captain Frutos Saavedra Meneses. Together, they designed new apparatus for measuring bases. He understood that older end standards were not accurate enough. He therefore chose a system using a single standard with microscopic measurements.
Ibáñez went to Paris. He worked with Jean Brunner to produce a calibrated measuring instrument. This instrument became known as the Spanish Standard. Its length was precisely measured against a French standard. The Spanish Standard was even replicated for use in Egypt.
Temperature was a major concern. Ibáñez meticulously assessed temperature’s effect on the standards. This was critical for accurate measurements.
In 1858, Ibáñez measured Spain’s central geodetic base with exceptional precision. He and his colleagues wrote a detailed report. This report was translated into French. The experiment validated the method of General Johann Jacob Bayer. Bayer was the founder of the International Association of Geodesy.
From 1865 to 1868, Ibáñez surveyed the Balearic Islands. He devised a new instrument for faster measurements. In 1869, he took it to Southampton. There, Alexander Ross Clarke compared world length standards. The improved “Ibáñez apparatus” was later used in Switzerland.
In 1870, Ibáñez founded the Spanish National Geographic Institute. He directed it until 1889. At the time, it was the world’s largest geographic institute. It encompassed geodesy, cartography, statistics, and weights and measures.
Ibáñez played a key role in extending the Paris meridian. This involved connecting geodetic networks across Spain and Algeria. This remarkable project measured a meridian arc from Shetland to the Sahara.
Ibáñez also championed the metric system internationally. He represented Spain at the 1875 Metre Convention. He was the first president of the International Committee for Weights and Measures. His efforts led to the distribution of platinum-iridium metre prototypes. These defined the metre until 1960.
For his contributions, Ibáñez received the Légion d’Honneur and the Poncelet Prize. The Spanish government recognized his achievements by granting him the title of Marquis of Mulhacén.
The Memorial General Ibáñez de Ibero reminds us of a visionary leader. He advanced geodesy and standardized measurement. His work laid the foundation for modern metrology. His legacy extends across science and international collaboration.
