Reverend Frank Gibbs Allen (1836-1887) was an American prolific author. He was a great defender of faith, both as speaker and writer whether in his religious journals or in his debates. He published The Old Path Guide, which appeared first in the form of a magazine. Before his death he wrote Original Doctrinal Sermons, known as The Old Path Pulpit. Concerning Mr. Allen, the late President Robert Graham, publisher of his autobiography, said: "He was a sincere man; he was a conscientious man; he was a brave, true man; he was a pure-minded, godly man.
