The Bureau came into existence about two years ago, as a result of the work of the Special Grand jury which investigated the white slave traffic in New York City during the first half of the year 1910. One of the recommendations made by the jury in the presentment handed up at the termination of its labors was that a public commission be appointed to study the social evil. The foreman of the jury subsequently gave careful consideration to the character of the work which might properly be done by such a commission and the limitations under which it would operate. In this connection, separate personal conferences were held with over a hundred leading men and women in the city, among whom were lawyers, physicians, business men, bank presidents, presidents of commercial organizations, clergymen, settlement workers, social workers, labor leaders and reformers. These conferences led to the conclusion that a public commission would labor under a number of disadvantages, such as the fact that it would be short-lived; that its work would be done publicly; that at best it could hardly do more than present recommendations. It was also believed that the main reason why more results of a permanent character had not been obtained by the various organizations which had dealt with the subject of the social evil during the past ten or fifteen years was that most of these organizations were temporary. While active, they materially improved the situation, but as their efforts relaxed, there came the inevitable return to much the same conditions as before. The forces of evil are never greatly alarmed at the organization of investigating or reform bodies, for they know that these are generally composed of busy people, who cannot turn aside from their own affairs for any great length of time to carry on reforms, and that sooner or later their efforts will cease and the patient denizens of the underworld and their exploiters can then reappear and continue as before. So the conviction grew that in order to make a real and lasting improvement in conditions, a permanent organization should be created, the existence of which would not be dependent upon a temporary wave of reform nor upon the life of any man or group of men, but which would go on, generation after generation, continuously making warfare against the forces of evil. It also appeared that a private organization would have, among other advantages, a certain freedom from publicity and from political bias, which a publicly appointed commission could not easily avoid. Therefore, as the initial step, the Bureau of Social Hygiene was formed in the winter of 1911. Its present members are Miss Katharine Bement Davis, Superintendent of the New York State Reformatory for Women at Bedford Hills, New York; Paul M. Warburg, of the firm of Kuhn, Loeb & Company; Starr J. Murphy, of the New York Bar; and John D. Rockefeller, Jr. As the work develops, new members may be added.
