СКАЧАТЬ eighteen, but the legislature swore him in four years earlier because the absence of an official emperor was fueling political instability.

      Alberto Santos-Dumont was born during Pedro II’s reign, on July 20, 1873, in a remote outpost of Minas Gerais, the home state of Tiradentes. Alberto’s parents, Henrique Dumont and Francisca de Paula Santos, were first-generation Brazilians who lived in a district of the state named Joâo Aires. The town they resided in was Cabangu, but to call it a town exaggerated its size. At first Cabangu consisted of only their house. Henrique was an engineer, and he had won a contract to build a stretch of the Dom Pedro II railroad through this remote part of Minas Gerais. The railroad was one of the vast public-works projects that the emperor had planned, and so it was an honor for Henrique to receive the commission. The drawback was the necessity of living in isolation.

      By the time Alberto was six, the railway work was over, and his father, tapping into his wife’s inheritance, had moved the family south to fertile lands outside São Paulo and entered the coffee business. It was not an easy move. The land had to be cleared, five million coffee trees planted, elaborate facilities built to store, dry, and process the beans, and living quarters erected for the workers and foremen. The plantation was so large that Henrique built sixty miles of railway to span it and purchased seven locomotives. The work paid off. Henrique, nicknamed the coffee king by the press, soon had one of the country’s largest farms. With his newfound wealth, he could afford to import European tutors for his children and to send Alberto, when he was older, to private schools in São Paulo and Ouro Prêto.

      “Inhabitants of Europe comically picture these plantations to themselves as primitive stations of the boundless pampas, as innocent of the cart and wheelbarrow as of the electric light and telephone,” Santos-Dumont wrote when he was an adult. “There are such stations far in the interior. I have been through them … but they are not the coffee plantations of São Paulo. I can hardly imagine a more stimulating environment for a boy dreaming over mechanical inventions.” At the age of seven he drove the broad-wheeled “locomobiles,” the steam traction engines that carried the red coffee berries from the fields to his father’s railway. Five years later he sweet-talked a foreman into letting him fire up a huge Baldwin locomotive and haul a trainload of berries to the processing plant.

      Of Henrique’s eight children, it was Alberto, the sixth child and youngest of three sons, who took the most interest in the mechanics of coffee production. He knew every step in the long process. “I think it is not generally understood how scientifically a Brazilian coffee plantation may be operated,” he recalled, with the berries untouched by human hands from the moment they entered the train cars to the time their by-product was loaded onto transatlantic ships. In a memoir written in 1904, called My Air-Ships, Santos-Dumont lovingly described how his family processed the coffee. The first step was to transfer the berries to giant tanks

      where the water is continually renewed and agitated. Mud that has clung to the berries from the rains, and little stones, which have been mixed with them in the loading of the cars, go to the bottom, while the berries and the little sticks and bits of leaves float on the surface and are carried from the tank by means of a trough, whose bottom is pierced with innumerable little holes. Through these holes falls some of the water with the berries, while the little sticks and pieces of leaves float on.

      The fallen coffee berries are now clean. They are still the color and size of cherries. The red exterior is a hard pod, or polpa. Inside of each pod are two beans, each of which is covered with a skin of its own. The water which has fallen with the berries carries them on to the machine called the despolpador, which breaks the outside pod and frees the beans. Long tubes, called “driers,” now receive the beans, still wet and with their skins on them. In these driers the beans are continually agitated in hot air.

      Coffee is very delicate. It must be handled carefully. Therefore the dried beans are lifted by the cups of an endless-chain elevator to a height whence they slide down an inclined trough to … the coffee machine house.

      The beans were then carried by a second elevator to the processing plant. The first machine they encountered was a ventilator, a series of vibrating sieves that let the coffee beans slip through but trapped any remaining sticks, leaves, and pebbles, impurities that would break the next machine.

      Another endless-chain elevator carries the beans to a height whence they fall through an inclined trough into the descascador, or “skinner.” It is a highly delicate machine; if the spaces between are a trifle too big, the coffee passes without being skinned, while if they are too small, they break the beans.

      Another elevator carries the skinned beans with their skins to another ventilator, in which the skins are blown away.

      Still another elevator takes the now clean beans up and throws them into the “separator,” a great copper tube two yards in diameter and about seven yards long, resting at a slight incline. Through the separator tube the coffee slides. As it is pierced at first with little holes, the smaller beans fall through them. Further along it is pierced with larger holes, and through these the medium-sized beans fall; and further still along are yet larger holes for the large, round beans called “mocha.” Each grade falls into the hopper, beneath which are stationed weighing scales and men with coffee sacks. As the sacks fill up to the required weight, they are replaced by empty ones; and the tied and labeled sacks are shipped to Europe.

      As a boy, Santos-Dumont spent whole days watching the machines and teaching himself to fix them. They were always breaking down.

      In particular, the moving sieves were continually getting out of order. While they were not heavy, they moved back and forth horizontally at great speed and took an enormous amount of motive power. The belts were always being changed, and I remember the fruitless efforts of all of us to remedy the mechanical defects of the device.

      Now, is it not curious that these troublesome shifting sieves were the only machines at the coffee works that were not rotary? They were not rotary, and they were bad. I think this put me as a boy, against all agitating devices in mechanics, and in favor of the more easily handled and more serviceable rotary movement….

      This was a prejudice that would serve him well when he built flying machines as an adult.

      Alberto was also the handyman around the house. His mother’s sewing machine often jammed, and she expected him to stop whatever he was doing and repair it. When arms or legs fell off his sisters’ dolls, he was the one who reattached them. When the wheels on his brothers’ bicycles started to wobble, he was the one who realigned them.

      Alberto was a loner and a dreamer, preferring the company of plantation machinery to a meal with his family. The atmosphere in Alberto’s house was often tense. His mother was deeply religious and superstitious, and his father, a man of reason and science, openly mocked her beliefs at family dinners. Although Henrique was pleased by his youngest son’s fascination with technology, he did not understand why Alberto had no interest in hunting, roughhousing, and the other manly activities that his brothers liked. Alberto never joined the men on all-day horseback expeditions and picnics to the far reaches of the land.

      At night he stayed up late reading. His father, who had received his engineering training in Paris at the Ecole Centrale des Arts et Métiers, had stacks of books lying around the house, in French, English, and Portuguese. Alberto paged through most of them, even the technical manuals. His favorites were science fiction. He loved Jules Verne’s vision of a sky populated with flying machines and had read all his novels by the age of ten. He learned from his father’s engineering texts that the hot-air balloon had been invented in 1783, by Joseph and Etienne Montgolfier, papermakers in Annonay, СКАЧАТЬ
