Great Engineers & Scientists

In 1676, Sir Isaac Newton wrote "If I have seen further it is by standing on ye shoulders of Giants." In this blog, we take Newton's words to heart, and recognize the many great engineers and scientists upon whose shoulders we stand.

So who do you think of when you hear "Great Engineer"? Let us know! Submit a few paragraphs about that person and we'll add him or her to the pantheon. Please provide a citation for the material that you submit so that we can verify it. Please note - it has to be original material. We cannot publish copywritten material or bulk text taken from books or other sites (including Wikipedia).

Louis Blériot, Aircraft Designer

Posted July 26, 2007 2:37 PM

Louis Blériot was a French engineer and aircraft designer who flew the first motorized aircraft across the English Channel and headed a successful aircraft company, the Société Pour Aviation et ses Derives (SPAD).

Early Career

Louis Charles-Joseph Blériot was born in Cambria, France on July 1, 1872. He studied engineering at the École Centrale Paris and graduated with a degree in Arts and Trades. Though best remembered for his flying machines, Blériot began his career by designing automobile headlights. He amassed a small fortune during his youth, but decided to devote his life's work to aviation after attending a local exhibition in 1901. Captivated by Clement Ader's bat-wing flying machine, Blériot first built a motorized ornithopter, a bird-like craft that was designed to fly by flapping its wings. Blériot's idea was as old as Icarus, the character from Greek mythology who flew too close to the sun, but the result – failure – was very much the same.

The Blériot-Voisin Company

In 1903, Louis Blériot joined forces with Gabriel Voisin, another young aircraft designer, to form Europe's first commercial aircraft manufacturing business. Although the Blériot-Voisin company was short-lived, the duo developed first a floatplane glider and then a motorized biplane. The inventors clashed frequently, however, and Gabriel Voisin bought out Louis Blériot's share of the business in 1906. While Voisin reformed the company with help from his brother Charles, Blériot started work on his own designs. He also taught himself to fly and served as his own test pilot. Blériot's first plane crash in 1907 was the first of many brushes with injury and death. Of the first 10 aircraft that he built, only one could sustain flight for more than 10 minutes.

Trial and Error

Unlike the Wright Brothers, Louis Blériot worked mainly by trial and error, rejecting a more systematic approach in favor of experimenting with various designs. After ending his partnership with Gabriel Voisin, Blériot built gliders, box-kite biplanes, and finally monoplanes. Although some historians credit Trajan Vui, a Romanian inventor, as the inventor of the first monoplane, others describe Louis Blériot as "the father of the modern airplane". In 1907 – the year after Vui flew a monoplane 40 feet – Blériot made a short hop in a canard-style aircraft (right) at Bagatelle, France. The French engineer later extended his monoplane's wingspan to 16.5 ft., but a crash on April 19, 1907 left the aircraft damaged beyond repair.

The Legendary Blériot XI

By 1908, Louis Blériot had spent most of the money he had amassed while working as an automotive engineer. He had also squandered most of his wife's inheritance. According to legend, Alicia Blériot saved her husband's aviation career by rescuing a boy who was about to fall off the balcony of a Paris apartment building. As luck would have it, the boy's father was a wealthy man who demonstrated his appreciation by offering to fund Louis Blériot's latest experiment, a monoplane called the Blériot XI. While this story may sound suspect, the engineer's interest in using the Blériot XI to win a thousand-pound prize was very real. The contest, a 22-mile flight over ocean waters, would also secure Blériot a place in aviation history.

On July 25, 1909, Louis Blériot made the first flight across the English Channel in a heavier-than-air machine, traveling from Les Barraques, France to Dover, England in 36.5 minutes. The wooden aircraft that Blériot landed near Dover Castle upset Britain's sense of aerial invincibility and netted the French inventor a large sum of money from the London Daily Mail, the newspaper which had sponsored the cross-channel contest. News of the French flier's success also stoked demand for the Blériot XI. At the request of his wife Alicia, Louis Blériot agreed to abandon competitive flying and focus on restoring the family's fortunes. By the end of 1909, the inventor had founded a factory which built "Channel crossing type" airplanes at a cost of £400. Blériot also licensed his winning design to several foreign firms.

When World War I began in 1914, Louis Blériot turned his Société Pour Aviation et ses Derives (SPAD) into one of France's leading manufactures of combat aircraft. During this "war to end all wars", SPAD built more than 5,600 aircraft for France and exported hundreds more to Great Britain and other Allied countries.

Louis Blériot died on August 2, 1936.

...then he died 30 years before the Battle of Hastings!!!!! I guess that was a misprint!!!

Or was he like King Arthur's Merlin and lived backwards!!!

My maternal Grandmother was on the Cliffs of Dover on that memorable day to welcome and see him as a young Teenager......she never forgot it!!

There is also a small statue on the seafront at Dover commemorating the Blériot landing!!

He was a visionary, for sure, but not quite a Merlin! I've corrected the date of his death to 1936.
