No man has gone before us in these depths, no one knows where we go nor what we see, nothing so strangely beautiful was ever presented to us, and spontaneously we ask each other the same question: are we not dreaming?

— É.-A. Martel, "Les causses du Languedoc", Conférences de l'exposition universelle internationale de 1889
Édouard-Alfred Martel was born in Pontoise, Seine-et-Oise on 1 July 1859.
Born into a family of lawyers, he studied at the Lycée Condorcet in Paris.
Early on, he became passionate about geography and the natural sciences and in 1877 he won first prize in an open competition for geography.
He was a great reader of the works of Jules Verne.
In 1866, while holidaying with his parents, he visited the Caves of Gargas in the Pyrenees.
Other trips allowed him to travel to Germany, Austria and Italy.
In 1879, he visited Postojna Cave in Slovenia, an extensive cave system.

In 1886, after completing his military service, he earned a law degree and became a licensed attorney with the Commercial Court of the Seine.
Martel devotes his leisure and holiday time to travels across France.
From 1883, he conducts work on the karstic plateaus of the Causses, shaped by the gorges of the Tarn, Jonte, Dourbie and Lot.

In June 1888, he began his caving career in the Bramabiau gorge in Gard.
He and several companions entered a rock cavity where a stream known as Bonheur sinks and reappears farther along the Bramabiau Gorge.
That same June with the same team he explored the Dargilan Cave along the Jonte Gorge over a mile away.
In 1889 he visited Padirac Cave, near Gramat.
He climbed down the entrance chasm and reached an underground river at a depth of 100m.
Martel and his cousin Gaupillat set off to explore with a canoe, discovering two kilometres of new passage.
Martel later bought the Padirac Cave, and turned it into a show cave.

In July 1890 he married Aline de Launay, sister of Louis de Launay, a professor of geology and future member of the Academy of Sciences.
Collaboration with Louis de Launay provide a scientific basis for some of Martel publications, including articles in the journal La Nature, which Martel and Launay were later editors.
In 1894, he published The Abyss, a book in which he describes the wonders of the underworld he discovered and visited during the six seasons of exploration he undertook from 1888 to 1893.
During this period, he visited and indexed more than 230 caves.

In 1895, he ventured further afield and organised an expedition to Ireland and England.
He discovered the underground lake of Marble Arch in Northern Ireland.
In Yorkshire he made the first complete descent, after a partial descent by Englishman John Birkbeck in 1842, into the pothole of Gaping Gill.
He reached the Main Chamber, 170 feet lower than Birkbeck had ventured.
That same year, he founded the Speleological Society and starts a periodic newsletter, Spelunca.

In 1896, he was invited by the Archduke Luis Salvator, a cousin of Emperor Franz Joseph of Austria, to visit their country.
With his foreman and journeyman Louis Armand, he explored several caves on the island of Mallorca.
In the Cave of Drach near Porto Cristo he discovered the largest underground lake known at the time.

Martel's explorations intensified around this time.
His priority is to explore the caves of Causses.
He also explored the caves and caverns of the limestone regions of Savoie, Jura, Provence and the Pyrenees.
He traveled throughout Europe, Belgium, Dalmatia, Bosnia and Herzegovina, Montenegro, where he investigated the course of the Trebišnjica, considered the one of the longest underground rivers in the world.
In 1899 he finally left professional life to devote himself to his scientific research.
He served as editor of La Nature from 1905 to 1909 and was a member of the Société de géographie, of which he was elected president.
In 1912, he spent three days exploring in Mammoth Cave, Kentucky where he undertook scientific work including barometric determinations of the elevations of the cave's different levels.
Martel was active in cave exploration from 1888–
