He was born in Pittsburgh, March 2, 1838. His parents were poor, his father being a carpenter and he himself built the little log cabin in which the family lived. When David was a baby only a few months old, he lost the sight of one eye by inflammation resulting from a severe cold. When about three years old, he noiselessly followed his sister into the cellar one day, intending in a spirit of mischief to blow out the candle she was carrying. Just as he leaned over to do it, she, unconscious that he was there, raised up, thrusting the candle in her hand right into his eye. The little boy's cry of pain was the first warning of his presence. The eye was injured, but probably he would not entirely have lost its sight had he not been attacked shortly after this with scarlet fever. When he recovered from this illness he was entirely blind. But the affliction did not change his sweet, loving disposition. He entered as best he could into the games and sports of childhood and grew rugged and strong. One day, while playing in the road, he was nearly run over by a carriage driven by a lady. Learning the little fellow was blind, she became interested in him and told his father of the school for the blind in Philadelphia. His parents decided to send him to it, and at five years of age he was sent over the mountains, making the journey in five days by canal. He was a bright, diligent pupil and a great reader, showing even at an early age his passion for music. When eight years old, he learned the flute. Soon he could play the violin and piano, and in his twelfth year he began playing the organ. All these instruments he took up and mastered himself without special instruction. In mathematics, James G. Blaine was his instructor for two years. After leaving school his struggles to succeed as an organist were hard and hitter. Despite his unusual ability, it was difficult to secure a position. He met with far more refusals than encouragement. But he was persistent and cheerful. Finally success came. Two days before Easter the organist of an Episcopal church was suddenly incapacitated and no one could be found to play the music. Professor Wood offered himself. The rector's wife read the music to him. He learned it in an hour, and rehearsal and the services passed off without a break. He was immediately engaged, his salary being one hundred dollars a year, his next position paid him fifty dollars a year. In 1864, he went to St. Stephen's Episcopal Church, Philadelphia, as choirmaster and organist, which position he still holds, playing at The Temple in the evenings only. He is to-day one of the most widely known organists of the country, being acknowledged everywhere a master of the instrument. He is a member of the faculty of the Philadelphia Musical Academy, principal of the music department in the Pennsylvania School for the Blind. It is said he has trained more good organists than any other teacher in Philadelphia.
