By age 12, he was sing­ing al­to in the choir at the Oak Street Meth­od­ist Church in Nor­ris­town. At 13, he was con­vert­ed by the per­so­nal in­vi­ta­tion of his bro­ther.

Mer­e­dith him­self com­posed over 1,000 songs. Dur­ing World War I, he served in France with the Young Men Chris­tian’s As­so­ci­a­tion.
