Topic XXVII
The Negro as an Inventor
HENRY E. BAKER.
Henry E. Baker is one of the most useful men in Washington. His life stands out in strong contrast to that of so many of our educated colored men who have come to Washington, obtained positions in the government service, and shriveled up so far as public usefulness is concerned. He is an active member of the Berean Baptist Church, being its treasurer, an office he has held for several years. For ten years he has been secretary, the executive officer of the Industrial Building and Savings Company, and a director of the Capital Savings Bank. His most notable characteristic is his public spirit, having been connected with almost every well-directed movement in this city for the last fifteen years, looking to the betterment of the condition of his race, especially in the matter of opening up business opportunities for them. The estimation in which he is held by those who know him best is attested by the fact that he is almost invariably called to the position of treasurer in every organization of which he is a member. Born just before the War in Columbus, Miss., he attended the public school of his home and also the Columbus Union Academy. He passed the entrance examination at Annapolis, and was admitted into the Naval Academy as cadet midshipman in 1875, where he remained nearly two years. In 1877, he was appointed “copyist” in the United States Patent Office, where he is at present employed, and where he was promoted, through the several intervening grades, to the position of Second Assistant Examiner at $1,600 per annum. He attended the Ben-Hyde Benton School of Technology in this city from 1877 to 1879; entered the law department of Howard University in 1879, graduating in 1881, at the head of his class, and from the post-graduate course in 1883.
He was married in May, 1893, at Lexington, Ky., to Miss Violetta K. Clark, of Detroit, Mich., who graces a cozy home at 2348 Sixth Street, N. W.
It is quite within the mark to say that no class of men of modern times has made so distinct a contribution to what is popularly called “modern civilization” as have the inventors of the world, and it is equally within bounds to say that the American inventor has led all the rest in the practical utility as well as in the scientific perfection of his inventive skill. Within the century just past the inventors of America have done more than was done in all the preceding centuries to multiply the comforts and minimize the burdens of domestic life. What Washington and Grant, Sherman and Sheridan did for the glory of America was done, and more, by Whitney, Morse, Thompson, Howe, Ericsson, Colt, Bell, Corliss, Edison, McCormick, and a host of other Americans, native and naturalized, to promote the progress of American inventive skill, and thus firmly to establish this country in the front rank of the enlightened nations of the world.
The true measure of a nation’s worth in the great family of nations is proportionate to that nation’s contribution to the welfare and happiness of the whole; and similarly, an individual is measured by the contribution he makes to the well being of the community in which he lives. If inventions therefore have played the important part here assigned to them in the gradual development of our complex national life, it becomes important to know what contribution the American Negro has made to the inventive skill of this country.
Unfortunately for the seeker after this particular information the public records of the United States government offer practically no assistance, since the public records distinguish only as to nations and not as to races. The Englishman and the American may instantly find out how each stands in the list of patentees, but the Irishman and the Negro are kept in the dark—especially the latter.
The official records of the United States Patent Office, with a single exception, give no hint whatever that of the thousands of mechanical inventions for which patents are granted annually by the government, any patent has ever been granted to a Negro. The single exception was the name of Henry Blair of Maryland, to whom the public records refer as “a colored man,” stating that he was granted a patent for a corn harvester in 1834 and another patent for a similar invention in 1836.
It is altogether safe to assume that this Henry Blair was a “free person of color,” as the language of those days would have phrased it; for the government seemed committed to the theory that “a slave could not take out a patent for his invention.” And this dictum gave rise to some rather embarrassing situations on more occasions than one. For instance, in 1857, a Negro slave, living with his master in the state of Mississippi, perfected a valuable invention which his master sought to have protected by a patent. Now, in law, a patent is a contract between the government and the inventor or his assignees. The slave, although the inventor, could not under the law be a party to a contract, and therefore could not secure the patent himself. His master applied for the patent, but was refused on the ground that inasmuch as he was not the inventor and could not be the assignee of a slave, he could not properly make the required oath. The master was not satisfied with this interpretation of the law by the Commissioner of Patents, and at once appealed from the latter’s decision to the Secretary of the Interior, who, in 1858, referred the case to the Attorney-General of the United States. This latter official, who was Hon. Jeremiah S. Black, of Pennsylvania, confirmed the decision of the Commissioner of Patent, and neither master nor slave was ever able to get a patent for the slave’s invention. This case reported on page 171 of volume 9, of “Opinions of Attorneys-General, United States.”
Another instance of a similar character occurred a few years later, in 1862, when a slave belonging to Jefferson Davis, President of the Confederacy, invented a propeller for vessels. He constructed an excellent model of his invention, displaying remarkable mechanical skill in wood and metal working. He was not able to get his invention patented, but the merits of his invention were commented upon approvingly by a number of influential Southern newspapers, and his propeller was finally put in use by the Confederate navy. With the barrier of slavery cast aside, a new opportunity was opened to the Negro inventor, and the purpose of this article is to show what use he has made of that opportunity.
It must still be borne in mind that the records of the United States Patent Office do not show whether a patentee is a Negro or a Caucasian, and that to ascertain what the Negro has accomplished in the field of invention other sources of information had to be utilized; and finally, that the very omission from the public records of all data calculated to identify a given invention with the Negro race completely destroys the possibility of arriving at any definite conclusion as to the exact number and character of negro inventions.
Judging from what has been duly authenticated as Negro inventions patented by the United States, it is entirely reasonable to assume that many hundreds of valuable inventions have been patented by Negro inventors for which the race will never receive due credit. This is the more unfortunate since the race now, perhaps, more than ever before, needs the help of every fact in its favor to offset as far as possible the many discreditable things that the daily papers are all too eager to publish against it.
It appears that no systematic effort was ever made by the government to collect information as to the number of inventions by Negroes until January, 1900, when the then Commissioner of Patents, Hon. Charles H. Duell, undertook the task. Previous to that time the United States Patent Office had received numerous requests from all parts of the country for information on that point, and the uniform reply was that the official records of the Patent Office did not show whether an inventor was colored or white, and that the office had no way of obtaining such information.
Notwithstanding this fact, however, an employee of the Patent Office had undertaken to collect a list of such patents, and this list was used in selecting a small exhibit of Negro inventions. First, for the Cotton Centennial at New Orleans, in 1884; again for the World’s Fair at Chicago, in 1893; and, lastly, for the Southern Exposition at Atlanta in 1895. But it was reserved for the United States Commission to the Paris Exposition of 1900 to make the first definite effort to obtain this information, and at its request the following letter by the Commissioner of Patents was addressed to hundreds of patent lawyers throughout the country, to large manufacturing establishments, to the various newspapers edited by colored men, and to prominent men of the race:
DEPARTMENT OF THE INTERIOR,
United States Patent Office.
Washington, D. C., Jan. 26, 1900.
Dear Sir:
This Office is endeavoring to obtain information concerning patents issued to colored inventors, in accordance with a request from the United States Commission to the Paris Exposition of 1900, to be used in preparing the “Negro Exhibit.”
To aid in this work, you are requested to send to this Office, in the enclosed envelope, which will not require a postage stamp, the names of any colored inventors you can furnish, together with the date of grant, title of invention, and patent number, so that a list without errors can be prepared.
You will confer a special favor by aiding in the preparation of this list by filling in the blank form below, and sending in any replies as promptly as possible. Should you be unable to furnish any data, will you kindly inform us of that fact?
Very respectfully,
C. H. Duell,
Commissioner of Patents.
=============================================================================== | NAME. | NUMBER. | DATE. | INVENTION. | +——+——+——+——+ | | | | | | | | | | | | | | | | | | | | +——+——+——+——+
The replies to this letter showed that the correspondents personally knew of and could identify by name, date and number more than four hundred patents granted by the United States to colored inventors. The letters also showed that nearly as many more colored inventors had completed their inventions, and had applied to patent lawyers throughout the country for assistance in obtaining patents for their inventions, but finally abandoned the effort through lack of means to prosecute their applications. The list of the patented inventions as furnished mainly by the letters above named is printed below, and shows that, beginning first with agricultural implements and culinary utensils, which circumscribed the character of his earlier employment, the Negro inventor gradually widened the field of his inventive effort until he had well nigh covered the whole range of patentable subjects.
A study of the list will disclose the fact that the Negro inventor has very often, like his white brother, caught the spirit of invention, and not being contented with a single success, has frequently been led to exert his energies along many different lines of inventions.
Elijah McCoy, of Detroit, Mich., heads the list with twenty-eight patents, relating particularly to lubricating appliances for engines both stationary and locomotive, but covering also a large variety of other subjects. The next is Granville T. Woods, of Cincinnati, whose inventions are confined almost exclusively to electricity, and cover a very wide range of devices for the utilitarian application of this wonderful force. Mr. W. B. Purvis, of Philadelphia, comes next with sixteen patents relating especially to paper bag machinery, but including a few other subjects as well. Mr. F. J. Ferrell, of New York, has ten patents on valves adapted for a variety of uses. Then comes ex-Congressman Geo. W. Murray of South Carolina, with eight patents on agricultural implements. Mr. Henry Creamer has seven patents on steam traps, and more than a dozen among the number have patented as many as five different inventions.
Time and space will not admit of any extended notice of many individual patentees, but mention should be made of a few of them.
Granville T. Woods is called the “Black Edison” because of his persistent and successful investigations into the mystery of electricity. Among his inventions may be found valuable improvements in telegraphy, important telephone instruments, a system for telegraphing from moving trains, an electric railway, a phonograph, and an automatic cut-off for an electric circuit. One of his telephone inventions was sold to the American Bell Telephone Company, who is said to have paid Mr. Woods handsomely for his patent. Mr. Ferrell’s inventions of valves laid the foundation for a large and highly successful manufacturing and commercial enterprise which he now conducts in the city of New York.
Mr. Elijah McCoy succeeded in placing his lubricators on many of the steam car and steamboat engines in the northwest and also on some of the ocean steamers, and from these he receives a valuable annual royalty.
Mr. Matzeliger, of Massachusetts, is credited with being the pioneer in the art of attaching soles to shoes by machinery; and Mr. Joseph Lee, of Boston, is said to have placed his kneading machine in many of the first-class bakeries and hotels in Boston and New York, from which he receives a substantial royalty.
So far as is known to the writer Miss Miriam E. Benjamin, of Massachusetts, is the only colored woman who has received a patent for an invention, and the principle of her invention, that of a gong signal, has just been adopted in the United States House of Representatives in signalling for the pages to attend upon members who want them for errands. Formerly the pages were signalled by members clapping their hands, and the noise incident to this method was frequently a great disturbance of the House proceedings. The new system just adopted involves merely the pressing of a button on the member’s chair, and this rings a small gong while displaying a signal on the back of the chair.
Another invention by a young colored man which has attracted considerable attention is the rapid-fire gun by Mr. Eugene Burkins, of Chicago. This gun has been examined by officers of the War and Navy Departments, and has been pronounced a valuable contribution to the scientific equipments for military and naval warfare.
The following description of Mr. Burkins’ gun appeared in Howard’s American Magazine some months ago:
“A brief description of the gun is not exactly out of place, although the Scientific American and other technical journals have long since given it to the world. It is an improvement upon all that has yet been done in the way of ordnance, and the principles involved in its construction can be applied to any size of gun, from a one-inch barker to a thirty-six-inch thunderer. The model as it now stands weighs 475 pounds, measures four inches at breech, and is constructed of the finest of gun brass at a cost of $3,500. There is a magazine at the breech in which a large number of heavy shells can be held in reserve, and in the action of the gun these slip down to their places and are fired at the rate of fourteen a minute, an improvement on the Maxim gun of four shots. The gun is elevated upon a revolving turret with electrical connections, enabling the gunner to direct the action of the machine with a touch of his finger. Firing, reloading and ejection of shells are all effected by electricity, and a child could conduct the work of manning the gun as easily as anyone.”
These inventions show how completely in error are those who constantly assert that the Negro has made no lasting contribution to the civilization of the age, and they prove conclusively that under favorable environment he is capable of performing his whole duty in the work of mankind whether it be tilling the earth with his hoe or advancing the world by his thought.
