His full power as a labor reservoir was not seen until the transformation of the [Great] War. In a few short months, 500,000 black laborers came north to fill the void made by the stoppage of immigration and the rush of white working men into the munitions industry. This was simply a foretaste of what will continue to happen. The Negro still is the mightiest single group of labor force in the United States. As this labor grows more intelligent, self-conscious and efficient, it will turn to higher and higher grades of work and it will reinforce the workingman’s point of view.25
It must not be assumed, however, that the labor of the Negro has been simply the muscle-straining unintelligent work of the lowest grade. On the contrary he has appeared both as personal servant, skilled laborer and inventor. That the Negroes of colonial times were not all ignorant savages is shown by the advertisements concerning them. Continually, runaway slaves are described as speaking very good English; sometimes as speaking not only English but Dutch and French. Some could read and write and play musical instruments. Others were blacksmiths, limeburners, bricklayers and cobblers. Others were noted as having considerable sums of money.26 In the early days in the South, the whole conduct of the house was in the hands of the Negro house servant; as butler, cook, nurse, valet and maid, the Negro conducted family life.
Thus by social contact and mingling of blood, the Negro house servant became closely identified with the civilization of the South and contributed to it in many ways. For a long time before emancipation the house servant had been pushing steadily upward; in many cases he had learned to read and write despite the law. Sometimes he had entered the skilled trades and was enabled by hiring his time to earn money of his own, and in rare cases to buy his own freedom. Sometimes he was freed and sent north and given money and land; but even when he was in the South and in the family and an ambitious menial, he influenced the language and the imagination of his masters; the children were nursed at the breast of black women, and in daily intercourse the master was thrown in the company of Negroes more often than in the company of white people.
From this servile work there went a natural development. The private cook became the public cook in boarding houses, and restaurant keeper. The butler became the caterer; the “Black Mammy” became the nurse, and the work of all these in their various lines was of great influence. The cooks and caterers led and developed the art of good-eating throughout the South and particularly in cities like New Orleans and Charleston; and in northern cities like Philadelphia and New York their methods of cooking chicken and terrapin, their invention of ice cream and their general good taste set a standard which has seldom been surpassed in the world. Moreover, it gave economic independence to numbers of Negroes. It enabled them to educate their children and it furnished to the abolition movement a class of educated colored people with some money who were able to help. After emancipation these descendants of the house servant became the leading class of American Negroes. Notwithstanding the social stigma connected with menial service and still lingering there, partially because slaves and Freedmen were so closely connected with it, it is without doubt one of the most important of the Negro’s gifts to America.
During the existence of slavery all credit for inventions was denied the Negro slave, as a slave could not take out a patent. Nevertheless Negroes did most of the mechanical work in the South before the Civil War and more than one suggestion came from them for improving machinery. We are told that in Virginia: “The county records of the seventeenth century reveal the presence of many Negro mechanics in the colony during that period, this being especially the case with carpenters and coopers” [Philip Alexander Bruce].27
As example of slave mechanics, it is stated that among the slaves of the first Robert Beverly was a carpenter valued at £30, and that Ralph Wormeley, of Middlesex county, owned a cooper and a carpenter each valued at £35. Colonel William Byrd mentions the use of Negroes in iron mining in 1732. In New Jersey slaves were employed as miners, ironworkers, sawmill hands, house and ship carpenters, wheelwrights, coopers, tanners, shoemakers, millers and bakers, among other employments, before the Revolutionary War. As early as 1708, there were enough slave mechanics in Pennsylvania to make the Freedmen feel their competition severely. In Massachusetts and other states we hear of an occasional artisan.28
During the early part of the nineteenth century the Negro artisans increased. The Spanish Governor Salcedo, early in the nineteenth century, in trying to keep the province of Louisiana loyal to Spain, made the militia officers swear allegiance, and among them were two companies of colored men from New Orleans “who composed all the mechanics which the city possessed.”29
Later, black refugees from San Domingo saved Louisiana from economic ruin. Formerly, Louisiana had had prosperous sugar-makers; but these industries had been dead for nearly twenty-five years when the attempt to market sugar was revived. Two Spaniards erected near New Orleans a distillery and a battery of sugar kettles and began to manufacture rum and syrup. They had little success until Etienne de Boré, a colored San Dominican, appeared. “Face to face with ruin because of the failure of the indigo crop, he staked his all on the granulation of sugar. He enlisted the services of these successful San Dominicans and went to work. In all American history there can be fewer scenes more dramatic than the one described by careful historians of Louisiana, the day when the final test was made and the electrical word was passed around, ‘It granulates!’”
De Boré sold $12,000 worth of sugar that year. Agriculture in the Delta began to flourish and seven years later New Orleans was selling 2,000,000 gallons of rum, 250,000 gallons of molasses and 5,000,000 pounds of sugar. It was the beginning of the commercial reign of one of the great commercial cities of America and it started with the black refugees from San Domingo.30
In the District of Columbia many “were superior mechanics.” Olmsted, in his journeys through the slave states just before the Civil War, found slave artisans in all the states. In Virginia they worked in tobacco factories, ran steamboats, made barrels, etc. On a South Carolina plantation he was told by the master that the Negro mechanic “exercised as much skill and ingenuity as the ordinary mechanics that he was used to employ in New England.” In Charleston and some other places they were employed in cotton factories. In Alabama he saw a black carpenter—careful and accurate calculator and excellent workman; he was bought for $2,000. In Louisiana he was told that master mechanics often bought up slave mechanics and acted as contractors. In Kentucky the slaves worked in factories for hempbagging, and in iron work on the Cumberland river, and also in tobacco factories. In the newspapers, advertisements for runaway mechanics were often seen, as, for instance a blacksmith in Texas, “very smart”; a mason in Virginia, etc. In Mobile, [Alabama] an advertisement read “good blacksmiths and horseshoers for sale on reasonable terms.”31
Such men naturally showed inventive genius, here and there. There is a strong claim that the real credit for the invention of the cotton gin is due to a Negro on the plantation where Eli Whitney worked. Negroes early invented devices for handling sails, corn harvesters, and an evaporating pan for refining sugar. In the United States Patent Office there is a record of 1,500 inventions made by Negroes and this is only a part of those that should be credited to Negroes as the race of the inventor is not usually recorded.
In 1846 Norbert Rillieux, a colored man of Louisiana, invented and patented a vacuum pan which revolutionized the method of refining sugar. He was a machinist and engineer of fine reputation, and devised a system of sewerage for New Orleans which the city refused to accept because of his color.
Sydney W. Winslow, president of the United Shoe Machinery Company, laid the foundation of his great organization by the purchase of an invention by a native of Dutch Guiana named Jan E. Matzeliger. Matzeliger was the son of a Negro woman and her husband, a Dutch engineer. He came to America as a young man and worked as a cobbler in Philadelphia and Lynn. He died in 1889 before he had realized the value of his invention.
Matzeliger invented a machine for lasting shoes. It held the shoe on the last, gripped and pulled the leather down around the sole and heel, guided and drove the nails into place and released a completed shoe from the machine. This patent was bought
