Alberto Santos-Dumont was born on 20 July 1873 in Palmira, Brazil. He was the sixth child of Henrique Dumont, a wealthy coffee farmer and engineer of French descent, and Francisca de Paula Santos.
Fascinated by mechanics and engines from an early age, Alberto developed an interest in aviation during a family trip to Europe in 1891. Although he briefly attended several educational institutions, he never completed a formal course of study, preferring to educate himself.
In 1897, Santos-Dumont settled in France, where he began learning about lighter-than-air aircraft. After his first balloon ascent in 1898, he designed and built his own balloons and a series of dirigibles, designated N-1 to N-10. He subsequently turned his attention to heavier-than-air flight, experimenting with both aeroplanes and a helicopter concept.
In 1906, Santos-Dumont introduced the Oiseau de Proie (Bird of Prey), an experimental aircraft initially assisted by a hydrogen balloon during take-off. Following further modifications, the improved Oiseau de Proie II made several short flights in October, earning Santos-Dumont his first aviation prize.
On 12 November 1906, at Bagatelle near Paris, Santos-Dumont achieved his most famous success. Flying his improved aircraft, he covered 220 metres at an average speed of 37.4 km/h, winning the French Aeroclub Award. The flight was officially observed and recognised by the Fédération Aéronautique Internationale (FAI), marking an important milestone in the development of aviation.
Santos-Dumont continued designing aircraft, including the Demoiselle series, whose N-20 version is regarded as an early practical ultralight aeroplane. However, the development of multiple sclerosis and the outbreak of the First World War deeply affected him. Opposed to the military use of aircraft, he campaigned unsuccessfully against their use in warfare.
Suffering from deteriorating health and profound depression, Alberto Santos-Dumont died by suicide on 23 July 1932, aged 59.
Today, he remains one of the most important pioneers of aviation. Brazil honours his legacy through the naming of Rio de Janeiro’s Santos Dumont Airport, while his birthplace, formerly Palmira, was renamed Santos-Dumont in 1932.
