Starting in the Detroit shop of O. F. Berdan, Henderson N. White dreamed a dream of truer, finer band instruments. His repair work and daily contact with musicians taught him the weaknesses of the instruments then used. And his musician’s instinct could not be content with their imperfections.
Setting himself to the task of making that dream come true, Mr. White soon gained more that a local reputation. Learning always from band masters who visited that little shop in Detroit; studying in every spare moment; and experimenting always; it wasn’t long before other cities heard about him.
