Dr. Wilder is a man of spotless character, and enjoys a striking appearance, a magnetic personality, and a brilliant and versatile mind. His early training was received in the public schools of his native city. He spent a season in the classical department of Howard University, and from there he went to Howard Medical College, from which he graduated in the year 1888. Availing himself of the unrivalled opportunities afforded by the Freedman's Hospital, he rapidly acquired both theoretical and practical knowledge, so that when he stepped into the world he possessed a preparation seldom equaled by the young practitioner. He has also the degree of Phar. D. from Howard. He located in Washington, the capital of the nation, where today he enjoys a large and lucrative practice. His modest, sympathetic nature makes him an ideal man for the sick room. His ability has won professional recognition not only for himself but for others. He was for many years physician to the National Home for Destitute Colored Women and Children, and is today the examining surgeon for a number of benevolent and charitable organizations. He has been prominently connected with many of the business ventures of the colored people in the District of Columbia for the past ten years, and is ranked as a broad-minded, solid, public-spirited citizen--a grand object lesson for what is best and most progressive in the community. He has invested his earnings judiciously, so that today he has a competency seldom attained by a man of his years. The success gained, the making the most of himself, renders him the best advocate of truth, and a potent factor in the growth and development of the race. This plain, honest, earnest young man is a type of the generation since citizenship came--a splendid example of worth since the selfhood of the race has been partially recognized, and the members have been permitted to add their quota to the sum of human advancement and achievement. The hour calls for fact, not fancy--for flesh-and-blood examples of what has been done by the young manhood of the country. The interest here and now is due to the fact that he has had somewhat to say on a subject of vital moment, and has said it vigorously and eloquently. Here he is the champion of truth, performing a service in a dignified, scholarly manner, and so winning the praise and gratitude of all lovers of truth. His article must call a halt to those inconsiderate ones who persistently repeat what through haste and insufficient data has been given to the world as fact--as logical inference from scientific investigation.
